the ozone layer insulate earth :

TRUE

The atmosphere is composed of five major layers. These layers are, in order from the surface of the earth, troposphere, stratosphere, mesosphere, ionosphere, and exosphere.

troposphere - lowest layer that provides majority of our weather. contains four-fifths of air on the earth and extends to a maximum height of 11 miles at the equator and lesser height at the poles. 

stratosphere - extends to the height of 30 miles from the equator and it's the location of the ozone layer.

mesosphere - extends to the height of 52 miles from the equator and is where meteors generally burn up

ionosphere - extends to the height of 430 miles from the equator and is already considered as part of the outer space. It is where satellites orbit around the world.

exosphere - extends to the height range of 620 miles to 6,214 miles from the Earth's surface and merges with interplanetary space
