Atmosphere
|
|
By whet three main gases is heat energy absorbed by the atmosphere?
|
Water vapor, carbon dioxide, ozone.
|
|
What is the term for the trapping of heat inside the atmosphere?
|
Greenhouse effect
|
|
During the lunar night. a moon rock loses the heat it gained previously from the sun. What happened to this energy? Explain why the law of energy conservation has not been violated.
|
Its energy is not destroyed but transformed back into radiant energy (infrared waves) and released into space.
|
|
Let's say that, in a certain day, the temperatures in two places were the earth's surface are identical. One is a tropical rain forest, the other is a desert. Which place do u expect to develop colder temperature at night? Why?
|
Because water vapor contributes to the greenhouse effect, the temperature in the rain forest would decrease little at night. The temperature in the desert, however, would be decrease much more: the clear, dry air over the desert would allow more heat to escape from the atmosphere.
|
|
Why do u suppose that, as a general rule, nighttime temperatures are lower on clear nights then on cloudy ones?
|
Clouds contribute to the greenhouse effect - when it is cloudy, less heat is able to escape from the atmosphere.
