The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth creates pressure, absorbs most meteoroids and ultraviolet solar radiation, warms the surface through heat retention (greenhouse effect), allowing life and liquid water to exist on the Earth's surface, and reduces t… WebbThe original atmosphere of the Earth, Venus and Mars consisted of Hydrogen and Helium. Those light elements, however, were heated to escape velocity by solar radiation and thus this atmosphere escaped.
