Question

Quizplus · Accepted Answer

Terrestrial planets do not have much atomic or molecular hydrogen in their atmospheres because of the process of thermal escape. The high temperatures in the early solar system caused the lighter gases to escape from the planets' atmospheres, and since hydrogen is the lightest and most abundant element, it was lost to space through thermal escape.
