the earth"s atmosphere..........

this is the labels of the atmosphere???

this is the earth labeled to tell you about the way you labeled the atmosphere. It shows you the way that the  atmosphere  is labeled the names of the earth you start with your names of the atmosphere and then the degrees.

this is the shooting star going into the earth and it is revolving and it it showing how the star is shooting to the earth.

this shows the way that the troposphere and the atmosphere to the earth and the latitude degrees...

this is the rotation that shows you ho we very thing rotates and it shows the tempter it shows the gravity waves the nonoshphere.

The Layered Atmosphere

Stand outside and look up. What do you see? You might see blue sky or wooly clouds. At night you might see stars, a satellite or a crescent moon. What you are not seeing, however, is the complexity of our atmosphere. The atmosphere is a protective layer of gasses that shelters all life on Earth, keeping temperatures within a relatively small range and blocking out harmful rays of sunlight.

The atmosphere has five different layers that are determined by the changes in temperature that happen with increasing altitude.

Living at the surface of the Earth, we are usually only aware of the events happening in the lowest layer, the troposphere, where all weather occurs. The base of this layer is warmer than its top because the air is heated by the surface of the Earth, which absorbs the Sun’s energy.

Above the troposphere lies the stratosphere where jet airplanes fly. Temperatures increase with altitude because of increasing amounts of ozone. The ozone layer within the stratosphere absorbs harmful ultraviolet rays of sunlight.

As the mesosphere extends upward above the stratosphere, temperatures decrease. The coldest parts of our atmosphere are located in this layer and can reach –90°C.

In the forth layer from Earth’s surface, the thermosphere, the air is thin, meaning that there are far fewer air molecules. The thermosphere is very sensitive to solar activity and can heat up to 1,500°C or higher when the Sun is active making an aurora that lights up the night sky. Astronauts orbiting Earth in the space station or space shuttle spend their time in this layer.

The upper layer of our atmosphere, where atoms and molecules escape into space, is called the exosphere.
