Descripe the troposphere and stratosphere and mesosphere. be sure to include what altitude one culd find this layer and what is found in the layer

Troposphere, stratosphere and mesosphere are the layers of Earth's atmosphere. Their features are as it follows in the explanation bellow.

Explanation:

Troposphere is the lowest layer of atmsphere, and this is the area where all weather phenomenon and life happen. Troposphere goes up to 18 kilometers in height. This is also the densiest layer of atmoshere where almost all water, clouds and air processes exist. Troposhpere is the only one sphere where life is possible.

Stratosphere is the layer between 18-20 km up to 50-55 km in height, above the Earth's surface. This layer is well known for great concentration of ozone (somewhere between 20 and 25 km), and that area is called - ozone layer. Ozone is very important because it absorbs most of the Sun's ultraviolet radiation.

Mesosphere is the layer just above the stratosphere and it spreads between 50-55 km up to 80-90 km. Mesopshere is characterized by significant temperature drop (lower parts has around 0 degrees and uppermost parts are very cold, at -90 degrees Celsius). Upper segments of mesopshere is known as ionosphere. That is the layer with charged iones, and it is well known for formation of polar light (aurora)
