 Ranges from 0 km to 12 km  Lowest layer of the atmosphere  Where we live  Where almost all of the Earth’s weather occurs  “Tropo” means turning.

Tropo- means “turning” or “changing”. 3 Facts: the thinnest layer closest to Earth where we live Temperatures get colder as you increase altitude.

Layers of the Atmosphere

Troposphere the thinnest layer closest to Earth where we live Tropo- means “turning” or “changing”. 3 Facts: the thinnest layer closest to Earth where we live Temperatures get colder as you increase altitude.

Stratosphere second layer contains the ozone layer traps heat Strato- means “layer”. 3 Facts: second layer contains the ozone layer traps heat Temperatures get warmer as you increase altitude.

Ozone Layer part of the stratosphere can be damaged by pollution Ozone is a type of oxygen gas that is helpful in blocking out radiation from the sun but harmful to humans. 3 Facts: part of the stratosphere can be damaged by pollution absorbs ultraviolet radiation Temperatures get warmer as you increase altitude.

Mesosphere third layer meteors burn up here has coldest temperatures Meso- means “middle”. 3 Facts: third layer meteors burn up here has coldest temperatures Temperatures get colder as you increase altitude.

Thermosphere fourth layer warmest temperatures Thermo- means “heat”. 3 Facts: fourth layer warmest temperatures gradually fades into space Temperatures get warmer as you increase altitude.

Ionosphere part of thermosphere Iono- means “charged particle”. 3 Facts: part of thermosphere Aurora Borealis found here (Northern Lights) radio signals bounce off of particles Temperatures get warmer as you increase altitude.

Exosphere part of thermosphere satellites orbit Earth Exo- means “outer”. 3 Facts: part of thermosphere satellites orbit Earth gradually fades into space Temperatures get warmer as you increase altitude.
