Earth atmosphere has five layers the five layers are troposphere, stratosphere, mesosphere, and the exosphere, and the thermosphere.
The troposphere is the lowest portion of Earth's Atmosphere.Troposphere is a layer of a atmosphere that which we are living and it gives more oxygen to humans to breathe .
Earth's stratosphere is minus 60 degrees F.Volcanic eruptions periodically eject material into the stratosphere
The mesosphere burns up meteors and keeps them from destroying the Earth's surface.We see shooting stars from the mesosphere.
The exosphere goes on into space so nobody know where it ends.It goes to 310 to 620 miles above the surface of the Earth.
The thermosphere roughly begins at a distance of 53 to 56 miles from the surface of the planet, and extends all the way up to 311 to 621 miles.
