Question

QUESTION 6 A basic history of global climate change is preserved in the stratigraphic record because o a the amount of sediment deposited is a function of climate o b depositional setting and the assemblages of organisms depend on the climate O c. the amount of fossils preserved in the rock record is dependent on climate ? d. characteristics of igneous rocks depend on climate because of variations in coong rates. QUESTION 7 In the illustration below, which part of Earth is receiving the most sunlight? Sun's rays 90 s Tropic of Cancer O C. Tropic of Capricom o d equator QUESTION 8 Water has a high heat capacity, which means that o a it can easily become very hot o b. small amounts of heat can increase water temperature dramatically o c. it can absorb a lot of heat without much change in temperature. o d itis a good indicator of temperature change QUESTION 9 Climate varies with latitude because of the o a distance from the sun. o b. angle of incidence. c. thickness of the atmosphere. o d abundance of greenhouse gases.

Explanation / Answer

Question 6: The history of global climate of earth is preserved in stratigraphic record of the subsurface because the igneous rocks which are formed due to cooling of magma have different size of grains depending upon the temperature such that if magma is cooling rapidly the grain size would be very small and if magma is cooling slowly then large crystals will develop in the igneous rocks. Hence d is correct answer.

Question 7: The rays that are coming from the sun have same intensity but if we see the figure we’ll find out that in the regions nearer to pole will sunlight is spread on large area and hence the intensity of sunlight would be less near the polar regions and sunlight is coming almost perpendicularly on the areas near Tropic of Capricorn and hence c is correct answer.

Question 8: Water has high heat capacity and heat capacity is the amount of heat required to increase the temperature of any body a unit. Therefore water’s high heat capacity give water an amazing property to absorb high quantity of heat without any substantial increase in its temperature. Hence option c is correct.

Question 9: As mentioned in question 7 The angle of incidence of sunlight is the factor which varies the amount of heat that is going to received by anyplace and since the angle of incidence of sunlight becomes more and more parallel as we go towards poles and it becomes almost perpendicular at equator and hence option b is correct.

As per Chegg’s policy we are adviced to attempt only the first four parts of a questioner. Please post the remaining questions as a different questioner. Thanks
