What Is the Mesosphere, How Cold and High Is the Mesosphere, and What Does the Word Mesosphere Mean In Greek?

The Mesosphere is located above the stratosphere and directly below the thermosphere.

By the time you reach the mesosphere there is only one-thousandth the amount of breathable air as when you are at sea level.

The mesosphere is located about 50 to 85 kilometers, or 30 to 50 miles in the atmosphere above the Earth’s surface.

The temperatures in the upper mesosphere can be as low as -100 °C, or 173 K (-148 °F).

The word mesosphere comes from the Greek words “mesos”, which means middle, and “sphaira”, meaning ball.

The mesopause, or the is the top of the mesosphere, is the coldest place on Earth.
