Explanation / Answer
Hi Answer:
Q.Explain how the temperature difference between the poles and the equator drives the motion of the oceans and atmosphere.
Answer: The temperature at Poles is lower than the temperature of the equator. So that the hot water from equator moves towards the poles and cold water of poles moves towards the equator due to this movement there is setting up of a circular current ocean water and air current. This cycle is continued as when the cold water along with cold air reaches the equator it becomes warm and it again starts its journey towards poles and in this way, the cycle continues.
Q. What are the differences between ice caps and glaciers?
Answer: Ice caps are the stationary chunks or heap of ice whereas the glaciers are the movable ice bodies.
Q.How do ocean currents affect local climate?
Answer: As when air comes in contact with the surface water of ocean then the warm water of ocean make it warmer. As we know that the water has higher specific heat as compared to air so it warm slowly as compared to the air and this generates the pressure gradient between air in contact with land and that with water. This creates the wind flow. Due to this reason the ocean current effect the local climate.
Q.Why do we call groundwater in most areas a “nonrenewable resource”?
Answer: because groundwater available deep in the earth and once it is pumped out fully from the source it took a long time for groundwater aquifers to recharge. This time may be decades to centuries that’s why the groundwater is called nonrenewable source.
Q. What is the Gulf Stream?
Answer: It is a powerful ocean current in the Atlantic Ocean. It is the part of North Atlantic Subtropical Gyre, which is the large system of circular currents and strong powerful winds. Gulf stream starts from the Gulf of Mexico and goes up to the Atlantic at the tip of Florida.
Q. What countries are directly affected by the path of the Gulf Stream?
Answer: Mexico, Florida, eastern coastline of the United States and Newfoundland.
Q. Find out what kind of rock is below the soil in your town. How did you find out this information?
Answer: By analyzing the soil of the particular area we can determine the type of rocks present below the soil because soil contains the particles of rocks which are present below commonly known as the bedrocks.
Q. How many different trophic levels were represented in your last meal?
Answer: The trophic levels means the position in a food chain. In a food producer are always the first trophic level and decomposers are the last level. So the number of trophic levels depend upon the type of food you select. There is no limit of trophic level in a food chain. Suppose you took a combination of vegetables and beef in the meal, then there is two trophic level in food, the first level is vegetables (producer) the second is beef (consumer).
Q. What is the ozone layer? Where is it located? Why is it important to life on Earth?
Answer: Ozone layer is the allotropic form of Oxygen having formula O3. It is found in the region above 20-30 miles from the surface of the earth. In this region, most of the ultraviolet radiations coming from the sun are absorbed. The ozone is important for life on earth because it protects the earth and its creatures from harmful UV radiations which causes cancer.
Q. What steps would have to be taken to reduce the severity of the greenhouse effect?
Answer: Greenhouse effect can be reduced by reducing the emission of greenhouse gases. We can lower down the production of carbon dioxide by carpooling, walking, cycling. The electric cars also reduce the greenhouse effect. The carbon dioxide can also be reduced by planting more and more trees.
Q. Where do electric cars obtain their energy?
Answer: The electric cars obtain their energy from batteries which are charged by the electricity.
Q. Is it true they do not generate pollution because they have batteries?
Answer: Yes it's true that electric cars didn’t generate much pollution as compared to normal cars but for the charging the batteries we need electricity and which is produced by some nonrenewable sources like coal etc. which causes pollution. Hence we can not say that the electric cars are totally pollution free
