List the atmospheric layers, temperature, altitude and density of those layers, and a unique object found in those layers.
Fiesta28 [93]

Five layers of the atmosphere are troposphere, stratosphere, mesosphere, thermosphere and exosphere.

<u>Explanation:</u>

Troposphere is the lowermost layer of the atmosphere which is found in the 0-12 km range. The temperature of the troposphere ranges from 15°C to 51°C.  Aircrafts driven by propellers can access the troposphere only.

Stratosphere is the layer of atmosphere that is second from earth. It is found in the 12-50 km range. Its temperature ranges from -51°C to-15°C. Jet-powered aircraft can access the stratosphere.

Mesosphere is the third atmospheric layer. It is found in the 50-85 km range. Its temperature ranges from -15°C to-120°C. rockets and rocket-powered spacecraft can access the mesosphere.

Thermosphere is the fourth atmospheric layer. It is found in the 500-100 km range. Its temperature ranges to about 2000°C. the International Space Station orbits in the thermosphere.

Exosphere is the topmost atmospheric layer. It extends to 10000 km above earth. Its  temperature is greater than 2000°C. most of the satellites that orbit the earth are found in the exosphere.

The density of atmospheric layers decreases while moving up along the layers. Thus troposphere has the maximum density.
