Structure of the atmosphere
The atmosphere reaches up to 10,000 km high, although more than half of its mass is concentrated in the first 6 km and 75% in the first 11 km. It is not homogeneous because the gases are arranged in it according to their density, the densest being closer to the earth's surface.
Structure according to its chemical composition
- Homosphere (0 km to 60 km): It is made up of air, a mixture of gases whose main components are nitrogen, oxygen, argon, water and CO2.
Activity: Components of Air.
