In order for convection to transfer heat, particles need to

Answers

Answer: circulate and move within a liquid or gas

Explanation:

hope it helped xx

In order for convection to transfer heat, particles need to circulate and move within a liquid or gas.

What is the use of the convection?

Convection currents arise by the difference in particle density in the fluid. Generally, warmer particles are less dense and tend to rise, while colder particles are denser and tend to do the opposite motion.

For convection to occur, a propagating medium, usually fluid (liquid or gaseous), must exist, because convection cannot move through empty spaces. This process of heat propagation happens due to the emergence of convection currents in the fluids.

This happens, for example, when heating water in the stove. The deeper molecules near the fire heat up faster, becoming less dense than the molecules closer to the surface.

All bodies emit energy by radiation at all times. At temperatures close to the environment, this phenomenon can usually not be perceived by human eyes, but can be seen when the body is at very high temperatures, such as a glowing ember.

Therefore, In order for convection to transfer heat, particles need to circulate and move within a liquid or gas.

A volcanic eruption takes place in a location. Ash and gas are sent out into the air. Lava flows down the volcano into human habitation. Which Earth systems interact during this process? a.) geosphere, atmosphere, and biosphere B.) hydrosphere, geosphere, and biosphere C.) atmosphere, geosphere, and cryosphere D.) biosphere, cryosphere, and hydrosphere

Answers

The major Earth systems which interact during volcanic eruptions are Hydrosphere, geosphere, and biosphere. Volcanoes are the events in geosphere. Thus, the correct option is B.

What is Volcanic eruption?

A volcanic eruption is when lava and gas are released from a volcano explosively. The most dangerous type of eruption is called a 'glowing avalanche' which is released when a freshly erupted magma flows down the sides of a volcano.

A volcanic eruption can cause glaciers and icecaps to melt. The hot lava is released from the geosphere. The sulfuric acid erupted from the volcanoes combines with rain in the hydrosphere which makes the acid rain. When this acid rain reaches the surface of the Earth, it pulls minerals from the soil, which deprives valuable nutrients from the soil and increases the acidity of the water and affects the animals that live in it. This affects the hydrosphere and biosphere.

Therefore, the correct option is B.

what can a ecosystem survive without with

Answers

Final answer:

Ecosystems require components like sunlight, producers, consumers, and decomposers to function effectively. These components deliver crucial ecosystem services necessary for the survival of all living things, including humans.

Explanation:

For an ecosystem to live longer and thrive, certain elements are essential. These include sunlight or chemical compounds to provide energy, the presence of producers like plants and photosynthetic organisms to harness that energy, and consumers like animals that feed on these producers.

Decomposers such as bacteria and fungi are crucial as they recycle nutrients back into the ecosystem, ensuring that soils remain fertile and productive. Without these key components, and the multitude of services they provide, human life would struggle to exist as ecosystems purify our air and water, stabilize the climate, and support all aspects of biodiversity.

Ecosystem services are the goods and the support systems that sustain human life. This includes production of oxygen, decomposition of waste, regulation of climate, and the creation of soils necessary for agriculture. It is clear that without healthy ecosystems, survival of living things, including humans, would be compromised, as ecosystems are the cornerstone that upholds the intricate web of life on Earth.

Distinguish between an organisms habitat and its niche using the prairie dog as an example

Answers

Final answer:

An organism's habitat is its physical environment, like the grasslands for prairie dogs, while an organism's niche is its specific role within the ecosystem. Prairie dogs' niche includes burrowing and serving as prey, which is critical for many other species' survival, making them a keystone species. Without prairie dogs, the ecosystem might face collapse.

Explanation:

An organism's habitat is its physical environment. For prairie dogs, this would be the grasslands or prairies where they live. In contrast, an organism's niche refers to its specific role within the ecosystem. Prairie dogs, as a species, have a niche that includes their extensive burrowing activities and their role as a primary food source for predators.

Prairie dogs are a keystone species because their burrows provide critical shelter for many small animals and their existence as prey supports numerous predators. By creating and maintaining burrow systems, they also help to aerate the soil, which benefits plant growth, and their foraging behavior can influence the distribution of plant species.

Without prairie dogs, their ecosystem could potentially collapse due to the loss of these critical functions. For example, the burrows they dig offer protection and habitats for other species, which contributes to the overall biodiversity of the ecosystem. If prairie dogs were to disappear, the ripple effects would be profound, impacting both predators and other small animals reliant on the burrows for shelter.

The surface area/volume ratio is an important factor for one-celled organisms. As a cell's volume grows, its surface area/volume ratio __________, making it ______________ to acquire enough nutrients via diffusion.

Answers

The two words that go in the blanks I would guess they are looking for are "decreases" and "difficult".

Correct answer: Decreases, Difficult

As the cell continues to grow, its internal volume increases and its membrane expands. At a certain time, there is a situation when the volume of a cell increases more as compared to the surface area. As a result of that the surface area volume of cell decreases. As the surface area to volume ration decrease, the cell becomes larger.

Hence, as the cell continues to grow beyond a limit, all the material are not able to cross the membrane rapidly so that it maintains the increased cellular volume. It results to disturb the normal function of a cell.

Hello. This question is incomplete. The complete question is:

"Which of the following best describes the long-term impact of using a nonrenewable energy source?

A: Geothermal energy can disrupt the water table and harm water supplies. B: Nuclear power damages the atmosphere by producing air pollution. C: Burning biomass to produce energy releases greenhouse gases. D: Coal mining can pollute water supplies and kill fish and aquatic plants."

Answer:

D: Coal mining can pollute water supplies and kill fish and aquatic plants.

Explanation:

The use of non-renewable energy has proven to be a strong pollutant of ecosystems and biomes. Coal mining is an example of how the use of non-renewable energy degrades nature.

The environmental impacts of mining are diverse and varying in scale: from specific local problems to major biological, geomorphological, water and atmospheric changes. Therefore, knowing these problems and minimizing their effects is of great necessity to ensure the preservation of natural environments.

Coal mining can pollute the water supply and kill fish and aquatic plants. Not to mention the degradation of soil and vegetation that this activity promotes.
