Answer 2

The troposphere is the lowest layer of Earth's atmosphere, where most weather occurs. It extends from the Earth's surface up to an average height of about 7 miles (11 kilometers) at the poles and 12 miles (19 kilometers) at the equator. This is where we live and where most of the atmosphere's mass is concentrated.
