homosphere
Quick Summary
The homosphere is the lower part of Earth's atmosphere, extending up to about 100 km (60 miles). In this region, turbulent mixing is the primary force, ensuring that the composition of gases remains relatively constant regardless of altitude. This contrasts with the heterosphere above it, where gases separate based on molecular mass. The homosphere encompasses layers like the troposphere, stratosphere, and mesosphere, where weather phenomena and atmospheric processes occur. The composition of the homosphere is dominated by nitrogen and oxygen, with trace amounts of other gases.1234567
