The Earth Layers

These are the the layers of the atmosphere.

EXOSPHERE IS THE FIRST ATMOSPHERE

The outermost region of a planet's atmosphere. Is the outer region of the upper atmosphere extending from a base of 500–750 km altitude. The zone has a very low concentration of gases (mostly molecules of oxygen, hydrogen, and helium, although some are ionized). Gases can escape from it into space, as molecular collisions are much reduced because of the low gas density.

IN THIS PICTURE YOU SEE THE THERMOSPHERE

the region of the atmosphere above the mesosphere and below the height at which the atmosphere ceases to have the properties of a continuous medium. The thermosphere is characterized throughout by an increase in temperature with height.

THIS IS THE MESOSPHERIC

The region of the earth's atmosphere above the stratosphere and below the thermosphere, between about 30 and 50 miles (50 and 80 km) in altitude.

THIS IS THE STRATOSPHERE

The layer of the earth's atmosphere above the troposphere, extending to about 32 miles (50 km) above the earth's surface (the lower boundary of the mesosphere).the very highest levels of a profession or other sphere, or of prices or other quantities.

This is the Troposphere

Troposphere

The lowest region of the atmosphere, extending from the earth's surface to a height of about 3.7–6.2 miles (6–10 km), which is the lower boundary of the stratosphere.
