Where does Earth end and outer space begin?

When climbers climb Mount Everest, they routinely carry oxygen tanks, devices that allow them to breathe freely at high altitudes. This is necessary because the closer you get to the edge of Earth’s atmosphere, the less oxygen there is available compared to the abundant amounts at sea level.

This is just one example of how variable the Earth’s atmosphere is, showing the elemental composition of its layers, from the troposphere near sea level to the exosphere in its outermost regions. Four key characteristics define where each layer ends and begins National Weather Service: temperature change, chemical composition, density and the movement of the gases contained therein.
