The tropopause is the atmospheric boundary that demarcates the lowest two layers of the atmosphere of Earth – the troposphere and stratosphere – which occurs approximately 17 kilometres above the equa
The tropopause extends to high altitudes in the tropical latitudes and extends to low altitudes in the polar latitudes.
The atmosphere of Earth consists of a layer of mixed gas that is retained by gravity, surrounding the Earth's surface. It contains variable quantities of suspended aerosols and particulates that creat

…The tropopause is the atmospheric boundary that demarcates the lowest two layers of the atmosphere of Earth – the troposphere and stratosphere – which occurs approximately 17 kilometres (11 mi) above the equatorial regions, and approximately 9 kilometres (5.6…
Earth's atmosphere from space, showing a blue layer at the stratosphere, above the clouds of the troposphere. The Moon is visible as a crescent in the background.
Afterglow of the troposphere (orange), the stratosphere (blue) and the mesosphere (dark) at which atmospheric entry begins, leaving smoke trails, such as in this case of a spacecraft reentry
In 1960, Joseph Kittinger set a record by parachuting from a gondola at 31.3 km (19.4 mi)
Earth from orbit, showing sunlight filtered into a reddish hue by the troposphere, while casting shadows from different cloud types. The stratosphere forms a thin band of blue scattered sunlight along the horizon.
