NAME 1. The diagram below represents energy being absorbed and reradiated by the Earth. Is the greenhouse effect good or bad? 5. Equal areas of which surface would most likely absorb the most insolation? 1) smooth, black surface 2) smooth, white surface 3) rough, black surface 4) rough, white surface 6. Which diagram best shows how air inside a greenhouse warms as a result of energy from the Sun? 1) 2) Which type of energy is represented by the radiation at B? 1) ultraviolet rays 2) infrared energy 3) insolation 4) visible light 2. A gradual increase in atmospheric carbon dioxide would warm Earth s atmosphere because carbon dioxide is a 1) good reflector of ultraviolet radiation 2) poor reflector of ultraviolet radiation 3) good absorber of infrared radiation 4) poor absorber of infrared radiation 3. Ice samples from continental glaciers provide evidence that today's atmosphere contains more carbon dioxide than ancient atmospheres did. This increase concerns scientists because increased carbon dioxide may 1) cause plants to grow very rapidly 2) contribute to a rapid cooling of the oceans 3) contribute to a gradual warming of the atmosphere 4) cause a loss in the amount of radiant energy from the Sun 4. Increasing the amount of carbon dioxide in Earth s atmosphere increases atmospheric temperature because the carbon dioxide absorbs 1) incoming solar gamma ray radiation 2) incoming solar visible light radiation 3) outgoing terrestrial infrared radiation 4) outgoing terrestrial ultraviolet radiation 3) 4) 7. A person in Florida worked outdoors in sunlight for several hours on a day in July. Which type of clothing should the person have worn to absorb the least electromagnetic radiation? 1) dark colored with a smooth surface 2) light colored with a rough surface 3) dark colored with a rough surface 4) light colored with a smooth surface 8. An increase in which gas would cause the most greenhouse warming of Earth s atmosphere? 1) hydrogen 2) nitrogen 3) oxygen 4) carbon dioxide Version 2 Page 1 Barnard
9. Base your answer to the following question on the graph below which shows variations in Earth's monthly temperatures from normal Earth temperatures between January 1990 and January 1995. The addition of water vapor, carbon dioxide, and methane gas to the atmosphere changes Earth's climate. This change occurs primarily because these gases cause 1) warmer temperatures by absorbing infrared radiation 2) cooler temperatures by absorbing infrared radiation 3) cooler temperatures by absorbing ultraviolet radiation 4) warmer temperatures by absorbing ultraviolet radiation 10. Deforestation increases the greenhouse effect on Earth because deforestation causes the atmosphere to contain 1) less oxygen, which absorbs short-wave radiation 2) less carbon dioxide, which absorbs short-wave radiation 3) more carbon dioxide, which absorbs infrared radiation 4) more oxygen, which absorbs infrared radiation 11. Which of these characteristics identify an Earth surface that is likely to be the best absorber of insolation? 1) dark colored and smooth 2) dark colored and rough 3) light colored and rough 4) light colored and smooth 13. Why are some scientists concerned about an increase in the amount of carbon dioxide in the atmosphere? 1) An increase would change the decay rate of C 14. 2) An increase would cause more ultraviolet energy to strike the Earth's outer atmosphere. 3) An increase would cause an overall heating up of the Earth's atmosphere. 4) An increase would cause energy to flow from energy sinks to energy sources. 12. Which component of Earth s atmosphere is classified as a greenhouse gas? 1) helium 2) carbon dioxide 3) hydrogen 4) oxygen Version 2 Page 2 Barnard
14. The diagram below shows a greenhouse. What is the primary function of the clear glass of the greenhouse? 1) The glass allows short wavelengths of radiation to enter, but reduces the amount of longwavelength radiation that escapes. 2) The glass allows all wavelengths of radiation to enter and all wavelengths of radiation to escape. 3) The glass reduces the amount of insolation entering the greenhouse. 4) The glass allows long wavelengths of radiation to enter, but reduces the amount of shortwavelength radiation that escapes. 15. Base your answer to the following question on the diagram and table below. The diagram shows a cross section of a solar-energy collecting system constructed as a portion of a wall of a house. It consists of an energy-absorbing surface, a clear glass covering, and air ducts through the wall into the house. The table gives the house temperatures during a spring day. No other heat source is available for the house. What is the purpose of the clear glass covering of this solar collector? 1) The glass allows short-wave radiation to enter and traps long-wave reradiation. 2) The glass radiates ultraviolet energy. 3) The glass allows long-wave radiation to enter and traps short-wave reradiation. 4) The glass radiates infrared energy.

16. A square meter of surface of which of these natural areas would most likely absorb the most insolation during a clear day? 1) a beach with white sand 2) a fast-moving river 3) a dark-green forest 4) a snow-covered field 17. Which graph best shows the relationship between the concentration of carbon dioxide in Earth's atmosphere and the amount of infrared radiation absorbed by the atmosphere. 1) 2) 21. Why are carbon dioxide and water vapor called the greenhouse gases? 1) They are good reflectors of infrared radiation. 2) They are found in varying amounts in Earth's atmosphere. 3) They are found in fixed amounts in Earth's bedrock. 4) They are good absorbers of infrared radiation. 22. Earth s atmosphere is warmed when 1) x-ray radiation emitted by Earth is absorbed by nitrogen and carbon dioxide in the atmosphere 2) ultraviolet radiation emitted by Earth is absorbed by nitrogen and carbon dioxide in the atmosphere 3) gamma radiation emitted by Earth is absorbed by carbon dioxide and water vapor in the atmosphere 4) infrared radiation emitted by Earth is absorbed by carbon dioxide and water vapor in the atmosphere 3) 4) 18. An increase in the amount of which atmospheric gas is thought to cause global climate warming? 1) oxygen 2) hydrogen 3) nitrogen 4) carbon dioxide 19. Which two gases have been added to Earth s atmosphere in large amounts and are believed to have increased global warming by absorbing infrared radiation? 1) methane and carbon dioxide 2) hydrogen and helium 3) chlorine and nitrogen 4) neon and argon 20. Changing the color of the roof of a house from light to dark would probably increase the amount of solar energy that is 1) insulated 2) absorbed 3) created 4) reflected Version 2 Page 4 Barnard
23. Base your answer to the following question on the diagram below, which represents four stations, A, B, C, and D, in a laboratory investigation in which equal volumes of sand at the same starting temperature were heated by identical light sources. The light sources were the same distance from each station, but at different angles to the surfaces. Two thermometers were used at each station, one just above the surface and the other just below the surface. The lights were turned on for 30 minutes and then removed for the next 30 minutes. Temperatures were recorded each minute for the 60 minutes. Which type of sand surface would most likely absorb the most radiation? 1) dark-colored rough surface 2) light-colored rough surface 3) dark-colored smooth surface 4) light-colored smooth surface Version 2 Page 5 Barnard
