WebMost of the Earth's atmosphere (80 to 90%) is found in the troposphere, the atmospheric layer where we live. This layer, where the Earth's weather occurs, is within about 10 km (6 miles) of the Earth's surface. The stratosphere goes up to about 50 km (31 miles). Gravity is the reason the atmosphere is denser closer to the Earth's surface.
