by the radiation of heat back into space from the earth.
by the unequal heating of the earth’s surface.
by the heating of the clouds and atmosphere by incoming solar radiation.
The greenhouse effect is important in keeping the temperatures in our atmosphere relatively stable.
True
False
The greenhouse effect becomes a problem
when there is an increase in solar radiation.
when there is an increase in the amount of greenhouse gases in the atmosphere
when green plants produce too much oxygen, increasing the amount of oxygen in the atmosphere
It is believed that increasing amounts of greenhouse gases in the atmosphere will result in
