Answer:
Dams affect the migration pattern of many different fish, creating a couple of issues.
Answer:
Out of the given statements, the statement that best describes the impact of a dam on the environment is that it causes changes in the river ecosystem.
Explanation:
Dams are usually built on rivers that flow through valleys formed by two elevated landforms on two sides. Thus, when a dam is built, it interferes with the natural setting and stops the natural flow of the water. This makes the water levels behind the dam grow considerably. Many a times, the landforms in the surrounding regions get submerged in the water due to the increased levels of water. The natural movement of aquatic animals like fishes and crabs is also hindered by the dam.What country is bordered on the north by poland and germany
This would be the Czech Republic or Czechia
The country bordered on the north by Poland and Germany is the Czech Republic, known as Czechia. Poland's historical borders have fluctuated greatly, but the modern boundary was established after World War II. Germany's borders have also changed over time, affecting neighboring countries like Czechia.
The country that is bordered on the north by Poland and Germany is the Czech Republic, also known as Czechia. Throughout history, the borders of Poland have changed significantly. Initially, the Poland-Lithuania government extended from the Baltic Sea to near the Crimean Peninsula in the Black Sea during the mid-1500s. However, due to invasions and territorial changes, Poland vanished from the map between 1795 and 1918. Post World War II, modern Polish boundaries were set, establishing its border with Germany, Czechia, Slovakia, Ukraine, Belarus, Lithuania, and a part of Russia known as the Kaliningrad Oblast.
Germany, prior to unification in 1871 and subsequent territorial losses, held lands that are now part of Poland. After the Sudetenland incident and the shift in German borders, Czechoslovakia bordered both Germany and Poland, which can be seen as per historical maps. As borders evolved over time, Poland now shares its western border with Germany and its southern border with Czechia.
During what type of tide is the high tide the highest and the low tide the lowest?
The tides are periodic movements of the great masses of water on our planet as part of the gravitational attraction exerted by the moon and the sun on Earth.
In this sense, there are two very special cases:
The Spring and Neap tides.
Spring tides
Occur when there is a full moon or new moon, which makes the tides higher. During these lunar phases, the Moon, the Earth and the Sun are aligned and the gravitational attraction power is greater.
Neap tides
Occur when the moon, the earth and the sun form a right angle ([tex]90\º[/tex]), being the gravity attraction on the masses of water the minimum. This happens in the crescent and wanning phases.

At the East African Rift, the African Plate is separating into two smaller plates that are moving in opposite directions. Based on this, which type of boundary exists at the East African Rift?
Answer:
Divergent plate boundary
Explanation:
The African continent, the second largest in the world, is splitting in two parts. The African plate on which the African continent lies is actually after heavy geologic activity which causes it to split in two parts that are moving in opposite directions. This is a prime example of a divergent plate boundary. As the African plate gradually separates into the Nubian and Somali plates, they will open up a gap between them that will constantly grow. That gap will fill in with the ocean waters, splitting the two land masses with a natural barrier, as well as giving rise to a new sea, or maybe even an ocean over the course of millions of years.

What has been the main cause of climate change over the past 100 years? How do we know humans are causing the climate to change, rather than natural causes?
Answer:
The main cause of climate change over the past 100 years has been global warming that has occurred due to increased levels of greenhouse gases.
Explanation:
Nowadays, the human's dependence on fossil fuels has increased to its highest. The climate change that we are getting to witness lately is a result of a continued increase in the levels of greenhouse gases that are released from the burning of fossil fuels. The greenhouse gases trap the heat received from Solar insolation and that released from various human activities and contribute to the rising of temperature. The increase in the global mean temperature has caused the climate to change substantially over the past 100 years.The main cause of climate change over the past 100 years is human activities, particularly the combustion of fossil fuels. Scientists have studied past climate changes and compared them to current changes, finding that natural causes alone cannot explain the observed warming. Computer models further support that human activities are the primary drivers of recent climate change.
Explanation:The main cause of climate change over the past 100 years is human activities, particularly the combustion of fossil fuels. Burning fossil fuels releases greenhouse gases, such as carbon dioxide, into the atmosphere. These gases trap heat and contribute to the greenhouse effect, leading to an increase in global temperatures and changes in climate patterns.
We know that humans are causing climate change rather than natural causes through scientific research and evidence. Scientists have studied past climate changes and compared them to current changes. They have found that natural causes alone cannot explain the observed warming, especially since the mid-20th century. Additionally, computer models have been developed to simulate the climate and predict future changes. These models include both natural and human factors, and they show that human activities are the primary drivers of recent climate change.
Which of the following scenarios best describes the activity present along the Mid-Atlantic Ridge? Magma is created by partial melting of crustal material as it sinks. Magma wells up at the center of the ridge, which pushes the old seafloor apart as new seafloor is created. A plume of hot mantle material is pushing up against the crust, adding material to the crust to thicken it. Segments of seafloor slide past each other without creating or destroying crustal material. Old seafloor is consumed as it is forced beneath another segment of seafloor.
Answer:
Magma wells up at the center of the ridge, which pushes the old seafloor apart as new seafloor is created
Explanation:
The Mid-Atlantic Ridge is formed at the divergent boundaries of the North American and Eurasian plates, and the South American and African plates. This basically means that these plates are moving away from one another, living thinner, fragile crust behind them. The magma from the mantle manages to penetrate through it relatively easy, and as it reaches the ocean floor it quickly cools off and creates new crust. The magma continuously rises, and it piles up more and more new crust, while in meantime pushing the old crust sideways and moving it further away from center of the ridge from the the ocean spreading occurs.

What economic activity is located in the taiga of russia
Final answer:
The taiga of Russia is home to significant economic activities such as mining, timber harvesting, and oil exploration. These exploit the rich natural resources found in the region but also contribute to considerable environmental issues such as habitat loss and pollution.
Explanation:
The taiga of Russia, also known as the boreal forest or coniferous forest, plays a considerable role in the country's economy. The primary economic activities in the taiga include mining, timber harvesting, and oil exploration. These activities exploit the region's abundant natural resources such as oil, natural gas, timber, diamonds, gold, and other precious metals. The Kuzbas region, in particular, is renowned for coal, iron ore, and bauxite mining; timber processing; and steel and aluminum production. Agriculture also contributes to the economy in areas like the eastern Lake Baikal region, albeit on a smaller scale compared to mining and logging.
Environmental concerns are substantial, as the taiga is a fragile biome that is affected by pollution and habitat loss due to these economic activities. Air and water pollution from smelting processes and massive oil spills are some examples of environmental damage that has resulted from the exploitation of the taiga's resources. This biome, dominated by Type D climates, is one of the largest terrestrial biomes, covering expansive areas of Northern Hemisphere countries.

The rising average global temperature is having the greatest effect on the __________.
Answer:
Arctic
Explanation:
The global temperature is on the rise, though not as much as it is often portrayed in the media. It is a slow process, but even though the changes in the temperature are seemingly small, they manage to cause changes, at some places almost unnoticeable, at some places more dramatic. The area that is most affected so far is the Arctic. The reason for this is that the Arctic is mostly covered with ice, but ice over an ocean not over land. As the temperature rises, the edges of the ice are melting, thus entering the ocean waters, and the cycle of the ocean currents. As the water circulates, it peaks up warmth in the lower latitudes, moves toward the Arctic and manages to penetrate further north and contributes to further melting of the ice. The process continues constantly, so the little by little the Arctic is changing its appearance, which unfortunately causes lot of problems for the flora and fauna adapted to it.

how did monsoon in South Asia has historically influenced globalization
Answer:
The monsoon of South Asia is among several geographically distributed global monsoons. It affects the Indian subcontinent, where it is one of the oldest and most anticipated weather phenomena and an economically important pattern every year from June through September, but it is only partly understood and notoriously difficult to predict. Several theories have been proposed to explain the origin, process, strength, variability, distribution, and general vagaries of the monsoon, but understanding and predictability are still evolving.
The unique geographical features of the Indian subcontinent, along with associated atmospheric, oceanic, and geophysical factors, influence the behavior of the monsoon. Because of its effect on agriculture, on flora and fauna, and on the climates of nations such as Bangladesh, Bhutan, India, Nepal, Pakistan, and Sri Lanka — among other economic, social, and environmental effects — the monsoon is one of the most anticipated, tracked,[3] and studied weather phenomena in the region. It has a significant effect on the overall well-being of residents and has even been dubbed the "real finance minister of India
Explanation:
Does the presence of aerosols cause global temperatures to increase or decrease
Answer:
decrease
Explanation:
The aerosols have a reverse effect from that of the greenhouse gases. The effect of them is decreasing of the temperature on a global scale, so we can say that it causes an equally big danger, if not bigger one, than that of the greenhouse gases. The aerosols have the property to scatter the light, change the Earth's reflectivity, and are creating clouds. The scattering of the light and change of the reflectivity of the Earth cause much more weakened and dispersed light, thus causing lesser heating of the Earth and its atmosphere. The formation of clouds too has its effect, as the clouds formed by the aerosols are almost impenetrable for the light, weakening it a lot, so the places below these clouds experience sudden drastic drops in the temperature.

What are the main gases that cause acid rain?
Acid rain is the result of changing the pH of gases and water present in the atmosphere, producing precipitation (rain or snow), whose pH is lower than natural rainfall (generally pH = 5).
This phenomenon occurs due to the effect of two gases: sulfur dioxide [tex]SO_{2}[/tex] and nitrogen oxides [tex]NO_{x}[/tex].
Sulfur dioxide is naturally emanated in volcanic eruptions, but it is also produced in large quantities by the metallurgical industry. While nitrogen oxides are emitted in conjunction with [tex]SO_{2}[/tex] by factories, power plants and vehicles that work with petroleum products or burning coal.
Then, these toxic gases interact with the water vapor present in the atmosphere, forming sulfuric acid and nitric acid, then these chemicals fall to the ground with the precipitation thus forming acid rain.
What have caused the most recent mass extinction of species? A. Asteroids B. Ice ages C. Humans D. Volcanoes
Asteroids have caused the most recent mass extinction of species. Thus, option A is appropriate.
Asteroids, sometimes known as minor planets, are stony byproducts of the early solar system's formation, which took place about 4.6 billion years ago. There are 1,299,015 known asteroids at this time. The main asteroid belt, which is located between the planets Jupiter and Mars and orbits our Sun, contains the majority of this old space debris.
The Cretaceous-Paleogene catastrophe event is the most recent extinction event and the sole one that can be shown to have been brought on by a large asteroid impact. All nonavian dinosaur species, making up about 76 percent of all species on the earth, perished.

The most recent mass extinction of species, known as the Holocene or Anthropocene extinction, is primarily caused by human activities, which differs from past extinctions caused by natural catastrophic events like asteroid impacts and volcanic activity.
Explanation:
The most recent mass extinction, sometimes referred to as the Holocene or Anthropocene extinction, is attributed to human activities. Thus, the correct answer to what has caused the most recent mass extinction of species is C. Humans. This sixth mass extinction is characterized by the significant loss of species that is ongoing and is closely linked to humanity's impact on the environment, including habitat destruction, pollution, overhunting, and climate change. Notable examples of human-induced extinctions include the passenger pigeon and the dodo bird. This modern mass extinction is distinct from past mass extinctions, such as the one that occurred 65 million years ago caused by an asteroid impact that led to the demise of the dinosaurs, or the Late Permian mass extinction possibly caused by volcanic activity.
Why are volcanoes not found at transform boundaries?
The transform fault boundaries are not having the same characteristics as the convergent or divergent plate boundaries. The movement at the convergent and divergent plate boundaries is caused by pressure from below, thus vertical one, and also when they collide one of them moves diagonally downwards, or rather subducts. That leaves gaps at the plate boundaries and big cracks through which the magma can penetrate. At the transform boundaries it is a different situation. The plates engaged in this type of boundary are neither moving away from each other, nor they are colliding, but instead they slide past each other. By sliding past each other, the plates actually close in any gap that might have enables for magma to come out on the surface, so we don't see volcanoes along this type of boundaries. What is typical about the transform plate boundaries is the formation of faults that form because of the stress, and are parallel to the boundary.
Volcanoes are not found at transform boundaries because these boundaries involve two tectonic plates sliding past each other horizontally, not vertically. Without vertical plate movement, subduction, and thus magma formation, does not occur, so volcanoes typically can't exist at these boundaries.
Explanation:Volcanoes are generally not found at transform boundaries because of the way these types of boundaries function. All tectonic boundaries, including transform boundaries, play a role in the movement and formation of the Earth's crust. However, transform boundaries are characterized by two tectonic plates sliding past each other horizontally.
At a divergent boundary or a convergent boundary, one can typically find volcanoes because these boundaries involve the vertical movement of tectonic plates. In a convergent boundary, for example, one plate is pushed beneath another in a process called subduction, leading to magma formation and thus causing volcanic activity. On the contrary, transform boundaries do not have this vertical movement, hence there is no subduction, and without subduction, there is no magma formation, and consequently, there are no volcanoes.

In what present-day country is the chernobyl nuclear power plant?
Answer:
Ukraine
Explanation:
The Chernobyl nuclear plant created the biggest disaster a nuclear plant has made since they have been used. This nuclear plant was int he territory of the former Soviet Union, while nowadays it is located in the territory of Ukraine. This nuclear plant was located in the northern part of what is now Ukraine, right next to the border with present day Belarus. On April 26, 1986, the reactor design flaws and the breaching of protocol during a simulated power outage safety test led to a disaster, with the nuclear plant starting to spread radiation around it. The few towns and villages nearby were immediately evacuated, but lot of people were exposed to such high radiation levels that they died very quickly or soon after. Because of the movement of the air masses and the open and relatively flat space all around the plant, the radiation was spread around big portion of Europe, having very bad effects on the human health, as well as the animals and plants that were affected by it. The area to this day still has very high levels of radiation and it is totally abandoned by humans, though the plants and animals have returned and repopulated, thriving in the absence of humans.
Final answer:
The Chernobyl Nuclear Power Plant is located in Ukraine and was the site of a major nuclear disaster in April 1986, leading to significant radioactive material release and long-term environmental impact.
Explanation:
The Chernobyl Nuclear Power Plant is located in the present-day country of Ukraine. This site became infamous due to a catastrophic nuclear accident that occurred in April 1986, which at the time was part of the Soviet Union. The accident took place during an unauthorized experiment leading to an uncontrollable increase in the reactor's chain reaction. Without a containment building, a significant amount of radioactive material was released into the environment. As a result of the Chernobyl disaster, many plant workers and firefighters suffered from acute radiation sickness, with estimated long-term death tolls from subsequent radiation-induced diseases. Decades later, the ruined reactor was encased in a steel and concrete sarcophagus, but the area still experiences significant radiation issues, rendering the vicinity a largely uninhabitable wasteland.
How long does it take Mercury to complete one revolution around the sun?
Answer:
About 88 earth days.
Explanation:
It is much closer to the sun than the earth, and therefore has less distance to travel to orbit the sun.
Mercury is the smallest planet of the eight planets and is made up of rock and metal. One year on Mercury is only 88 Earth days. That's how long it takes for Mercury to orbit the sun. Mercury rotates very slowly, so its days are very long. A day on Mercury is 59 Earth days.
What is the human impact on the water cycle?
Final answer:
The human impact on the water cycle includes overuse and pollution, leading to scarcity and ecological disruption. Altered precipitation patterns due to climate change require infrastructure changes that further affect ecosystems.
Explanation:
The human impact on the water cycle has significant repercussions on global freshwater resources. Overuse and pollution pose serious threats to the limited supply of fresh water upon which over a billion people rely. Water pollution, including contaminants from sewage, chemicals, and industrial wastes, leads to the destruction of aquatic ecosystems and creates dead zones where life cannot be sustained.
Moreover, with climate change, we face altered patterns of precipitation, necessitating the continuous reconstruction of water infrastructure such as dams, canals, and pipelines, which further disrupt aquatic ecosystems and contribute to biodiversity loss. Striking a balance between water consumption and preservation is critical, especially in arid regions where water scarcity is increasingly prevalent.
