2. What process produces “heat” in our Sun? In other words, where does the Sun’s energy come from? ______________________________.

3. In order for a gas to become a liquid, does it need to need to absorb heat or lose it?

4. All weather occurs in one layer of the atmosphere. What layer is it? ______________________________.

5. By what method of transferring heat, does the heat from the Sun reach us on Earth? ______________________________.

6. It takes 1 calorie to raise 1 gram of water by 1 o C How warm would 200 g of water at 25 o C be after receiving 800 cal of heat? Would 200 g of iron at 25 o C heat up by the same amount if it received the same number of calories?

7. The Sun’s heat reaches the Earth through radiation. However, the air is mainly heated through contact with the warmed surface of the Earth. Thus, air is mainly heated through which of the 3 methods of transferring heat? ________________________.

8. Which type of heat transfer is responsible for “driving” the Earth’s plates to move?

9. Latitude affects the amount of heat received at the Earth’s surface. In general, we can say that as latitude increases [moves toward the poles], the amount of sunlight that heats the surface… (does what?) ___________________________.

10. Our atmosphere is a collection of different gasses surrounding the Earth. Why is it that these gasses exert a pressure on us? ________________________________

11. It is 30 o F and a low pressure is in the area. The current dew point is 32 o F … what is the weather like?

15. When air is heated, it undergoes certain changes. In the following categories, describe the changes that take place when air is heated. Speed of molecules: ___________________________________________ Volume: ___________________________________________ Density: ___________________________________________

16. Using what you know of temperature and pressure, Describe what the atmospheric pressure will be like at the equator and at the poles. ________________________________

17. If the temperature outside reaches the “Dew Point” the relative humidity will be… ________________________________

18. Describe what wind is caused by ________________________________

19. In terms of pressure, what direction does wind blow? ________________________________
