The troposphere is the lowest layer of Earth's atmosphere. Most of the mass (about 75-80%) of the atmosphere is in the troposphere. Most types of clouds are found in the troposphere, and almost all weather occurs within this layer.
STRATOSPHERE
The stratosphere is where you'll find the very important ozone layer. The ozone layer helps protect us from ultraviolet radiation (UV) from the sun.
-The stratosphere layer is 35 km thick.
-Cold air is found at the bottom of the stratosphere.
-Light air is found at the top of the stratosphere.
-Heavy air is found at the bottom of the stratosphere.
-Warm air is found at the top of the stratosphere.
MESOSPHERE
The mesosphere lies between the thermosphere and the stratosphere. “Meso” means middle, and this is the highest layer of the atmosphere in which the gases are all mixed up rather than being layered by their mass.
The mesosphere is the third and coldest layer of Earth's atmosphere, reaching about 130 degrees below zero. The mesosphere is also where most meteors, or space rocks and metal, burn up before they can crash to the ground. It's like a superhero's force field that protects the Earth!
THERMOSPHERE
The thermosphere is the layer in the Earth's atmosphere directly above the mesosphere and below the exosphere. Within this layer of the atmosphere, ultraviolet radiation causes photoionization/photodissociation of molecules, creating ions; the thermosphere thus constitutes the larger part of the ionosphere. Taking its name from the Greek θερμός (pronounced thermos) meaning heat, the thermosphere begins at about 80 km (50 mi) above sea level.
EXOSPHERE
The exosphere is the uppermost region of Earth's atmosphere as it gradually fades into the vacuum of space. The air in the exosphere is extremely thin - in many ways it is almost the same as the airless void of outer space.
