Question 3 What are the features associated with Karst topography? Explain the problems associated.
Answer:
Caves, caverns, sinkholes, funnel-shaped holes, underground rivers and lakes
Explanation:
The karst topography is found at places that are dominated by rocks made out of calcium carbonate, better known as limestone. These rocks react with the water very easily and get dissolved from it very easily. Because of the large scale dissolving, this type of topography has numerous specific features. Some of the most common features in the karst topography are the caves, sinkholes, caverns, funnel-shaped holes, underground rivers, underground lakes etc. All of them are very attractive and understandably cause a lot of interest, thus they are often tourist destinations, but more importantly of big scientific interest. The biggest problem with this topography is that it is generally not stable, and it is very common that the rocks can crumble, which makes them relatively dangerous if visited at certain periods of the year, especially when there is more precipitation.
Answer:
Caves and Sinkholes
Explanation:
Would you rather live downwind of a nuclear power plant or downwind of a coal-burning power plant? Explain the reason for your choice.
Answer:
downwind of a nuclear power plant
Explanation:
Living in close proximity to a nuclear power plant or coal-burning plant is not something that would be preferable by most people, especially when it comes to living on the downwind side of them, but if I had to choose it will be living downwind of a nuclear power plant. The nuclear power plant is not a polluter of the air, so living downwind of it will not be a problem for the human health. The coal-burning plant, on the other hand, is one of the heaviest polluters of the air, as it releases enormous amounts of carbon dioxide. This will have very negative effects to the human health, so it is a situation to be avoided if possible. The nuclear plant does comes with a risk, as most things, but the chances are very small that a catastrophe will occur, and even if it does, it doesn't really matter on which side of it the people are living if they are in the same area as the plant.
Answer:
Atomic power is the utilization of atomic responses that discharge atomic vitality to create heat, which most every now and again is then utilized in steam turbines to deliver power in an atomic power plant. As an atomic innovation, atomic power can be gotten from atomic parting, atomic rot and atomic combination responses. An atomic power plant is a warm power station in which the warmth source is an atomic reactor. As it is run of the mill of warm power stations, heat is utilized to create steam that drives a steam turbine associated with a generator that produces power.
Explanation:
Nuclear power:
Atomic power is a spotless and proficient method for bubbling water to make steam, which goes turbines to deliver power. With the exception of the reactor itself, atomic power stations work like most coal or gas-terminated power stations.
Nuclear power plant:
An atomic power plant is a warm power station in which the warmth source is an atomic reactor. As it is commonplace of warm power stations, heat is utilized to create steam that drives a steam turbine associated with a generator that produces power.

Clouds and rpeccicpitation are more likely on the __________ side of a mountain, due to ___________.
a. windward, overrunning
b. leeward, overrunning
c. windward, orographic lifting
d. leeward, orographic lifting
e. windward, surface divergence
Answer:
c. windward, orogrpahic lifting
Explanation:
The windward side of the mountains is always the side of that receives much more precipitation than the leeward side. The reason for this is that the moist air masses come on this side, and as they do, they are forced to go upward because of the higher terrain. As the air masses move up, they cool down very quickly, with the humidity reaching even 100%, and that almost always results in precipitation. This kind of upward movement of the air masses because of higher terrain in front of them is called orographic lifting. As the moisture will mostly be spent on the windward side, the leeward will mostly get dry winds moving downward, making it much drier.

Answer
A . biased samples.
Answer:
Researchers conducting "'web-based research" have trouble controlling who actually answers their "on-line questionnaires", which places limits on their research due to the possibility of research participant bias.
Explanation:
Most web-based researches are subject to bias because the 'participant' in the research, i.e. the one who answers the questions is unknown to the researcher and may not be as serious with his answers. The credibility of such research is often questionable. The researcher may not always fetch answers from the expected age group, or may get answers from anyone who doesn't fit in the criteria specified by the researcher. This makes the answers biased towards the preferences of the person who isn't even eligible to participate in the research.A town is built on the banks of a small lake on the edge of a desert. After some time, the townspeople discover that water from the lake has become too polluted to use. Describe one way that the lake may have been contaminated by the actions of the townspeople, and explain how the townspeople can remediate this problem.
The lake may have been contaminated by municipal water pollution caused by sewage, agricultural, and industrial waste. Remediation can involve upgrading water treatment facilities, promoting proper waste management, reducing harmful chemical use, and implementing restoration projects.
One way that the lake in the town may have been contaminated is through municipal water pollution. This can occur through untreated or partially treated human waste (sewage) entering the lake, potentially creating a hazardous environment for aquatic life and making the water unsafe for town use. Possible sources of contamination include sewage discharge, agricultural runoff containing pesticides and nitrogen, and industrial waste.
To remediate this problem, the townspeople should initiate a water treatment plan. This could involve upgrading sewage treatment facilities to ensure all wastewater is adequately treated before being released into the lake. Implementing proper waste disposal and management systems, as well as reducing the use of harmful chemicals that could run off into the lake, are crucial steps. Engaging in regular monitoring of the lake's water quality, promoting awareness about pollution prevention, and potentially introducing filtration systems or cleanup projects can also help restore the lake to a healthy state.
How are synclines and basins similar? How are they different?
Answer:
Similarity: Both the syncline and the basin present as a depression in the geographical relief. Difference: A syncline is a fold with the concavity facing upward, displaying layers that hang down toward the center of the structure. On the other hand, the basins have the elongated circular or circular folding patternExplanation:
A syncline is a type of folding formed on the terrestrial coast in which the strata appear inclined towards a central axis, due to the deformation of the sediments. On the other hand, a basin is a depression of the terrestrial surface formed by rebates of the lithosphere, in which the sediments are deposited or deposited, where they are buried and converted into thick piles of sedimentary rocks.
The poles appear to be slightly flattened in a Robinson Projection.
Question 1 options:
True
False
Answer:
True
Explanation:
The Robinson Projection Map is one of the numerous projections made. This map though because very popular among many international organizations and companies throughout the world in the second half of the 20th century. The Robinson Projection Map manages to represent all of the world, which of course is an advantage. Unlike some of the earlier map projections, this one had smaller distortions as the latitudes were becoming higher. It came a little weird though that the poles were flattened, as that is not how they are in reality, while the western and eastern part of the map were curled, giving it an unnatural appearance.

Explanation:
A research satellite of mass 200 kg circles the earth in an 3R orbit of average radiuswhere R is the radius of earth. Assuming the gravitational pull on a mass of 1 kg on the earth's surface to be 10 N, the pull on the satellite will be (a) 880 N (c) 885 N (b) 889 N (d) 892 N
The given options do not match with the given data. However, working with an orbit of radius 3R/2 the answer is 889N.
Explanation:
According to Newton's law of Gravitation, the force [tex]F[/tex] exerted between two bodies of masses [tex]M[/tex] and [tex]m[/tex] and separated by a distance [tex]R[/tex] is equal to the product of their masses and inversely proportional to the square of the distance:
[tex]F=G\frac{Mm}{R^2}[/tex]
Where [tex]G[/tex]is the gravitational constant, [tex]M[/tex] is the mass of the Earth in this case
.
If we are told the gravitational pull on a mass of [tex]m_{1}=1 kg[/tex]on the earth's surface to be 10 N, this means the force at the surface is:
[tex]F=10N=G\frac{Mm}{R^2}[/tex] (1)
Assuming the mass of the Earth and its radius constant that we will name [tex]g[/tex], we can say:
[tex]G\frac{M}{R^2}=g[/tex] (2)
Then:
[tex]10N=g.m_{1}=g.(1kg)[/tex] (3)
Finding [tex]g[/tex]:
[tex]g=\frac{10N}{1kg}=10m/s^2[/tex] (4)
Now, the gravitational pull at a certain height [tex]h[/tex] over the surface is:
[tex]F_{h}=G\frac{Mm_{2}}{{(R+h)}^2}[/tex] (5)
Where [tex]m_{2}[/tex] is the mass of the satellite.
If we are told the radius of the orbit of the research satellite is [tex]3R/2[/tex], this means [tex]R+h=3R/2[/tex]:
[tex]F_{h}=G\frac{Mm_{2}}{{(3R/2)}^2}=G\frac{M}{R^2}.\frac{4m_{2}}{9}[/tex] (7)
Substituting (4) in (7):
[tex]F_{h}=g\frac{4m_{2}}{9}[/tex] (8)
Knowing the mass of the research satellite is 200kg:
[tex]F_{h}=10m/s^2\frac{(4)(200kg)}{9}[/tex] (9)
Finally:
[tex]F_{h}=888.888N\approx 889N[/tex] This is the gravitational pull on the satellite with an orbit of radius 3R/2

True or False. A constellation is a set of stars grouped into a figure.
The correct answer is True.
Explanation
A constellation is a group of stars that when united by imaginary loops form a figure, these stars are connected imaginatively by loops to form these figures and are original from ancient cultures, mainly from the Middle East and Mediterranean Europe. The formation of constellations is due to the invariability of movement of the stars, on the other hand, the stars that form a constellation can be very far from each other and are only related by being part of a constellation. The celestial sphere is usually divided into two, the constellations that are to the north are known as northern constellations and those that are to the south southern constellations, these two are divided by means of the celestial equator. So, it is true, A constellation us a set of grouped into a figure.
True or False. Intracluster gas is cool.
Answer:
The answer to the question: Intracluster gas is cool, would be: false.
Explanation:
Known as the intracluster medium, or ICM, the intracluster gas is a plasma that can be seen in and around a cluster of stars, or galaxy cluster. Composed primarily of hydrogen and helium that can be see as an aura of a galaxy, one of the characteristics of this medium is that it is superheated, can reach really high temperatures, and therefore, this would make the above statement false.

1. What are the major causes of desertifcation?
2. What are the basic mechanisms of desertification?
3. What are the adverse effect of desertification for humans?
Please write your answer in details.
1. The two major causes of desertification are the climate variations and the human activities. The desertification is a process that is a growing concern in the world, as the deserts have been spreading out more and more. One of the reasons are the climate variations. The changes in the precipitation patterns have resulted in reduced precipitation levels at certain places, resulting in the dying out of the vegetation and gradually being replaced with barren land dominated by sand or rocks. The other major cause is the human activity. The humans have been destroying lot of the vegetation because of their own needs, as well as using the waters in the arid and semi-arid regions extensively, resulting in barren landscape with destroyed soil, quickly becoming desert or semi-desert.
2. The basic mechanism of desertification is the change in climate, which is triggering the reactivation of the dormant sand dunes. The climate is constantly changing, and that is not something new, and while it may have positive effects at certain places, it has negative ones in others. When the precipitation levels drop significantly at certain places, the vegetation is starting to die out, and to be replaced by a desert one. The soil is also getting downgraded significantly. This enables the winds to be much bigger factor in shaping the landscape. They start to pick up small particles from the barren land and disperse them, and as they do they create sand dunes gradually, creating a desert.
3. The adverse effects for the humans from the desertification are numerous. With the desertification, the areas become much less suitable for living, in certain occasions almost impossible. The soil is destroyed, thus the agriculture and farming of animals can not be performed, meaning that food can not be produced. The water reserves go significantly down, so there's not enough water for drinking or for the other needs of the humans. The winds are become a big problem, they are much stronger and often cause sand storms, which can even be deadly if someone is caught in the open. The climate is very harsh, the temperatures are very high and it is very dry, or if it is a cold desert, it will have both very high and very low temperatures, depending on the period of the year.

Gemstones are commonly found in pegmatites, which are igneous rocks that are ________. a. exceptionally mafic b. exceptionally coarse grained c. exceptionally fine grained d. extrusive, forming from lava
Answer:
Gemstones are commonly found in pegmatites, which are igneous rocks that are extusive or forming from lavaFinal answer:
Pegmatites are igneous rocks that are exceptionally coarse grained due to the slow cooling of magma deep within the Earth, which allows large crystals to grow.
Explanation:
Gemstones are commonly found in pegmatites, which are igneous rocks that are exceptionally coarse grained. Pegmatites are intrusive igneous rocks that form from magma cooling slowly deep beneath the Earth's surface, allowing large crystals to grow. Unlike extrusive igneous rocks, which cool quickly at the surface and are fine grained like basalt, the slow cooling of intrusive rocks like pegmatites results in the distinct large crystal size. Granite is another example of a coarse-grained intrusive igneous rock, which typically consists of minerals such as quartz and feldspar.
True or False. If you double the temperature of a blackbody, it will emit double the energy.
Answer:
true
Explanation:
All objects with a temperature above absolute zero (0 K, -273.15 oC) emit energy in the form of electromagnetic radiation.
A blackbody is a theoretical or model body which absorbs all radiation falling on it, reflecting or transmitting none. It is a hypothetical object which is a “perfect” absorber and a “perfect” emitter of radiation over all wavelengths.
The spectral distribution of the thermal energy radiated by a blackbody (i.e. the pattern of the intensity of the radiation over a range of wavelengths or frequencies) depends only on its temperature.
13. Is there a fundamental difference between milky quartz, smoky quartz, and rose quartz?
Answer:
Explanation:
Yes, the fundamental difference between these shades of quartz is in their mineralogy.
Pure quartz is made up of silica(SiO₂) in a framework silicate pattern. During the formation of these minerals, some other elements like certain metals can take up spaces in their lattices and crystal space. These other elements would serve as impurities in them and cause the different types of quartz we have. This is why some quartz appear rosy, some smoky, some milky e.t.c.
Milky quartz, smoky quartz, and rose quartz are variations of the mineral quartz with different colors caused by impurities. They have the same chemical composition and crystal structure.
Explanation:Milky quartz, smoky quartz, and rose quartz are all variations of the mineral quartz. The main difference between these types of quartz is their color. Milky quartz is white or translucent, smoky quartz is brown or black, and rose quartz is pink or rose-colored.
The color variations in quartz are caused by impurities within the crystal lattice. For example, smoky quartz gets its brown color from natural irradiation of aluminum impurities. Rose quartz gets its pink color from trace amounts of titanium, iron, or manganese impurities.
Although the color may differ, these variations of quartz still have the same chemical composition and crystal structure, which is SiO2 or silicon dioxide. They also have similar physical properties, such as hardness and transparency.

True or False. Opacity is a measure of how much light is blocked when it passes through a substance.
Answer:
True
Explanation:
The word "Opacity" is tied to the property of the materials in blocking much of the light.
Opacity depends on the degree of light passing through a material. When the light is largely blocked, it is said that the material is opaque. If the flow of light passing is quite large, the material is considered translucent. And if the light goes through the material in its entirety, this is a transparent material.
