Earth Atmosphere Diagram

thermosphere— temperature increases with height. The temperatures can rise to 1,500 degrees Celsius, but it would not feel warm because of the low air pressure in this layer.

The atmosphere of Earth is the layer of gases , commonly known as air , that surrounds the planet Earth and is retained by Earth's gravity . The atmosphere of Earth protects life on Earth by absorbing ultraviolet solar radiation , warming the surface through heat retention ( greenhouse effect ), and reducing temperature extremes between day and night (the diurnal temperature variation ).
