"WebThe atmosphere thus acts as a radiative blanket over Earth’s surface, hindering the loss of heat to space. The blanketing effect is greatest in the presence of low clouds and weakest for clear cold skies that contain little water vapour. Without this effect, the mean surface temperature of 15 °C (59 °F) would be some 30 °C colder. " - How does earth have an atmosphere

WebThe Greenhouse Effect. Energy from the Sun that makes its way to Earth can have trouble finding its way back out to space. The greenhouse effect causes some of this energy to be waylaid in the atmosphere, absorbed and released by greenhouse gases. Without the greenhouse effect, Earth’s temperature would be below freezing. WebEarth is not the only world with an atmosphere.
