AI overview

The troposphere is the lowest layer of Earth's atmosphere, where weather occurs and clouds form at various altitudes. It matters because it's the part of the atmosphere closest to us where most of the processes that affect weather and climate take place.

The troposphere is the lowest layer of the atmosphere of Earth. Pronounced , the name comes . It contains 80% of the total mass of the planetary atmosphere and 99% of the total mass of water vapor and aerosols, and is where most weather phenomena occur. From the planetary surface of the Earth, the average height of the troposphere is in the tropics; in the middle latitudes; and in the high latitudes of the polar regions in winter; thus the average height of the troposphere is .
