Biosphere.

There are many layers to the atmosphere. The layer that extends 50-85 kilometers is called the mesosphere. The top part of the mesosphere is the coldest part of the atmosphere.
This region of the atmosphere is called the homosphere. It is the lowest portion of the Earth's atmosphere and extends about 65 miles.
It extends about 75 miles. Earth's Atmosphere The Earth is surrounded by a blanket of air, which we call the atmosphere. It reaches over 560 kilometers (348 miles) from the surface of the Earth, so we are only able to see what occurs fairly close to the ground. Early attempts at studying the nature of the atmosphere used clues from the weather, the beautiful multi-colored sunsets and sunrises, and the twinkling of stars. With the use of sensitive instruments from space, we are able to get a better view of the functioning of our atmosphere.
It extends to 600-700 km above earth's surface
Nitrogen is about 79% of the Earth's atmosphere.

Thermosphere - extends from 80 km above the Earth Mesosphere - extends from 50 - 80 km above the Earth Stratosphere - extends from 15 - 50 above the Earth Troposphere - closest to the Earth
The thermosphere is the outer layer of the earth's atmosphere. It extends from 80 kilometers above the earth's surface to outer space.
There are many layers to the atmosphere. The layer that extends 50-85 kilometers is called the mesosphere. The top part of the mesosphere is the coldest part of the atmosphere.
The Moon of the Earth is outside the atmosphere of the Earth. The Earth's atmosphere extends a few dozen miles from the surface of the planet (you can't get enough air to breath already 10 kilometers up). The Moon is some 382000 kilometers from the Earth.
It is a mixture of gases, known as the earth's atmosphere.
The stratosphere I think
