Question

question 13
joe is explaining the causes of climate change to his son and provides this sequence of events.

1. solar radiation from the sun is directed at earth.
2. some radiation is reflected back from earths surface.
3. some of this radiation is absorbed by greenhouse gases.

4.

1. the atmosphere gets warmer.

which of these statements describes step 4?
the radiation is often absorbed into the atmosphere.
cloud cover and atmospheric moisture dilute the radiation.
methane and carbon dioxide attract the radiation.
no radiation escapes into space.

Explanation:

In the greenhouse - effect process, after greenhouse gases absorb radiation, the radiation is often absorbed into the atmosphere, which then leads to the atmosphere getting warmer. Cloud - cover and atmospheric moisture diluting the radiation does not directly follow the absorption by greenhouse gases in the climate - change cause sequence. Methane and carbon dioxide are greenhouse gases and their function is to absorb not just attract radiation. Also, some radiation does escape into space, just not all of it.

Answer:

The radiation is often absorbed into the atmosphere.
