11. The Earth’s surface mainly gives off (radiates) which form of energy? a. Infrared light b. Visible light c. Ultraviolet light d. The Earth’s surface does not give off energy It is radiating HEAT or Infrared (IR) radiation that was previously absorbed from the sun.

12. About 70% of the Sun’s energy directed toward Earth is absorbed by the Earth’s surface, clouds, and atmosphere. What happens to the rest of the energy? a. The energy is lost as it overcomes the Sun’s gravity. b. The energy is reflected by clouds, water, and land back into space. c. The energy is diminished as it travels through space. d. The energy is reflected by the Moon back into space

13. What happens to the rest of the energy? a. The energy is lost as it overcomes the Sun’s gravity. b. The energy is reflected by clouds, water, and land back into space. c. The energy is diminished as it travels through space. d. The energy is reflected by the Moon back into space No way … the moon is too small.

14. What happens to the rest of the energy? a. The energy is lost as it overcomes the Sun’s gravity. b. The energy is reflected by clouds, water, and land back into space. c. The energy is diminished as it travels through space. d. The energy is reflected by the Moon back into space Need a reason for it to diminish.

15. What happens to the rest of the energy? a. The energy is lost as it overcomes the Sun’s gravity. b. The energy is reflected by clouds, water, and land back into space. c. The energy is diminished as it travels through space. d. The energy is reflected by the Moon back into space Of the Sun’s incoming energy, about 30% is reflected back to space.

16. Weather is caused by the Sun’s energy warming the Earth’s surface unevenly. Which of the following is NOT a contributing factor to this uneven warming? a. Different surfaces warm at different rates. b. Different surfaces retain energy differently. c. The Sun is farther away during the winter. d. The Sun’s rays strike the surface at different angles depending on latitude.

17. Weather is caused by the Sun’s energy warming the Earth’s surface unevenly. Which of the following is NOT a contributing factor to this uneven warming? a. Different surfaces warm at different rates. b. Different surfaces retain energy differently. c. The Sun is farther away during the winter. d. The Sun’s rays strike the surface at different angles depending on latitude. That is a common misconception … the sun is NOT farther away, the TILT of the earth is the reason for the seasons. NOT TRUE

18. More of the Sun’s energy is received at the Earth’s tropical regions than in the arctic regions because the tropical regions a. are covered by a greater area of land. b. have more vegetation that absorbs the Sun’s energy. c. have a thinner atmosphere than the polar regions. d. receive sun rays closest to vertical.

19. More of the Sun’s energy is received at the Earth’s tropical regions than in the arctic regions because the tropical regions a. are covered by a greater area of land. b. have more vegetation that absorbs the Sun’s energy. c. have a thinner atmosphere than the polar regions. d. receive sun rays closest to vertical. Tropical regions (by the equator) receive more direct sunlight NO NOT NECESSARILY NO WAY

20. Tropical regions (by the equator) receive more direct sunlight

21. The following figure shows the angle of the sun’s rays hitting two different locations on the Earth’s surface. Which of the statements about the figure is most correct? A B

22. a. Area A = near the pole and Area B = near the equator. Warming of the Earth is more with Area B than Area A because Sun’s energy is spread over a wider area. b. Area A = near the pole and Area B = near the equator. Warming of the Earth is more with Area A than Area B because the atmosphere is thinner at the equator. c. Area A = near the equator and Area B = near the pole. Warming of the Earth is more with Area A than Area B because the atmosphere is thinner at the equator. d. Area A = near the equator and Area B = near the pole. Warming of the Earth is more with Area A than Area B because the Sun’s energy is concentrated within a smaller area. A B Area A has to be near equator due to direct sunlight.

23. a. Area A = near the pole and Area B = near the equator. Warming of the Earth is more with Area B than Area A because Sun’s energy is spread over a wider area. b. Area A = near the pole and Area B = near the equator. Warming of the Earth is more with Area A than Area B because the atmosphere is thinner at the equator. c. Area A = near the equator and Area B = near the pole. Warming of the Earth is more with Area A than Area B because the atmosphere is thinner at the equator. d. Area A = near the equator and Area B = near the pole. Warming of the Earth is more with Area A than Area B because the Sun’s energy is concentrated within a smaller area. A B Atmosphere is not thinner anywhere

24. a. Area A = near the pole and Area B = near the equator. Warming of the Earth is more with Area B than Area A because Sun’s energy is spread over a wider area. b. Area A = near the pole and Area B = near the equator. Warming of the Earth is more with Area A than Area B because the atmosphere is thinner at the equator. c. Area A = near the equator and Area B = near the pole. Warming of the Earth is more with Area A than Area B because the atmosphere is thinner at the equator. d. Area A = near the equator and Area B = near the pole. Warming of the Earth is more with Area A than Area B because the Sun’s energy is concentrated within a smaller area. A B This is the best choice.
