A. Greenhouse gases are needed to keep the Earth’s atmosphere warm.
B. Greenhouse gases absorb the majority of incoming shortwave radiation from the Sun.
C. The majority of longer-wavelength radiation emitted by the earth is absorbed by greenhouse gases.
D. Nitrous oxide and industrial halocarbons are greenhouse gases.
参考答案: B
本题详细解析:
Explanation: Greenhouse gases only absorb a small percentage of incoming shortwave radiation from the Sun. Greenhouse gases warm the earth (Choice A) because they let most incoming radiation through, which heats the surface of the earth and then absorbs the re-emitted longer wavelength radiation (Choice C). Nitrous oxide, which is anthropogenic in origin, as well as industrially generated halocarbons, are also greenhouse gases (Choice D) and enhance the greenhouse effect.
