What would happen if more of the sun's heat became trapped in earth's atmosphere,and less heat was released into space

Explanation:

A covalent bond is where electrons are shared equally between molecules. if you see the bottom of the page each oxygen is missing 2 electrons so they share two of one of their own with eachother and give oxygen a full octet. it doesnt have to be full to be a covallent bond but it just has to share them evenly rather than keep it to themselves
