Question 26

The process that keeps Earth warm when gases in the atmosphere trap heat from the sun is…

Answer 26

The Greenhouse Effect

Question 27

Water vapor is actually the largest contributor to the Earth's greenhouse effect. On average, it probably accounts for about 60% of the warming effect. Why are we more concerned about controlling other greenhouse gases and not water vapor?

Answer 27

Water vapor does not control Earth’s temperature, its levels are controlled by the temperature Increases in other gases increase the water vapor in the atmosphere Water vapor is only in the atmosphere for a few days before precipitating out

Question 28

Greenhouse gases like carbon dioxide trap heat and increase the temperature. Warmer air is able to hold more moisture. As the climate warms, air temperatures rise, and more evaporation from water sources and land occurs. This increases the amount of water vapor in the atmosphere which in turn increases the temperature even more. This is an example of a
