stratosphere
noun
Did you know?
The stratosphere (strato- simply means "layer" or "level") lies above the earth's weather and mostly changes very little. It contains the ozone layer, which shields us from the sun's ultraviolet radiation except where it's been harmed by manmade chemicals. The levels of the atmosphere are marked particularly by their temperatures; stratospheric temperatures rise only to around 32°—very moderate considering that temperatures in the troposphere below may descend to about -70° and those in the ionosphere above may rise to 1000°.
