layer shields the entire Earth from much of the harmful ultraviolet radiation that comes from the sun. .5 What is the relationship among the Earth’s atmosphere, the sun, and the rotation of the Earth? Answer: Two things energize the atmosphere: the Sun's heat and Earth's rotation. Because Earth is a sphere, the Sun does not warm every place on Earth equally. In places where the Sun is directly overhead, the incoming rays are perpendicular to the surface, and a maximum amount of heat is received per unit area. Because Earth is rotating, the flow of air toward the poles and the return flow toward the equator are constantly deflected sideways, creating the circulating air masses you see on weather maps. .6 What is the Coriolis effect? Answer: Earth's rotation produces the Coriolis effect, which causes winds to veer to the right in the northern hemisphere and to the left in the southern hemisphere. The effect strongly influences both the global pattern of wind systems and the pattern of ocean currents, including the deep-ocean thermohaline “conveyor belt” circulation. .7 How would you define climate? Answer: Climate is an average of weather patterns over a long period. The processes we think of as weather —wind, rain, snow, sunshine, storms, and even floods and droughts—are just temporary local variations when viewed against the more stable, longer-term background of global climate. The different climate zones are strongly related to the global pattern of atmospheric circulation. .8 How does the atmosphere regulate climate? Answer: The global patterns of airflow ultimately control the variety and distribution of Earth's climatic zones. The world's deserts are mostly concentrated along the 30°N and 30°S

The tropical jungles of Africa and South America lie near the equator, where we expect low barometric pressure and lots of warm, moist air. .9 What are the six global climate zones? What are the main climate effects on people and the environment? Answer: There are six basic types of climate: tropical, dry, temperate-humid, cold-humid, polar, and highland. The effects of climate on people and the environment could range from serve heats waves to blizzards and more hurricanes. It could also cause more droughts or flooding in areas. People with allergies may suffer more and insects like mosquitoes carrying diseases may be higher in count if it is more humid and wet.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
