What is the Stratosphere?
ScienceAtmosphere
Quick Answer
The stratosphere is the second major layer of Earth’s atmosphere, lying above the troposphere and below the mesosphere.
The Full Story
The stratosphere extends from roughly 10 to 50 kilometers above Earth, though its height varies with latitude and season. Unlike the turbulent troposphere below, it is relatively stable and layered, which is why jet aircraft often fly near its lower levels. Temperature increases with altitude in this layer because ozone absorbs ultraviolet radiation from the Sun. The presence of the ozone layer makes the stratosphere especially important for protecting life on Earth.
