Question

what is the greenhouse effect?

Answer 1

The greenhouse effect is a natural process, whereby the earths atmosphere traps some of the heat from the sun (mostly by methane and carbon dioxide gasses), warming the earth. Without it the earth would be unable to support life.

Answer 2

Answer:

During the day the sun shines through the atmosphere, then the surface of the earth warms up due to the sunlight. In the evening, the surface of the earth is able to cool and releases the heat back into the air. This is called the greenhouse effect because carbon dioxide (and other gasses in the atmosphere) do what the roof of a green house does.
