Answer:
Thermosphere – Oxygen-Warmer –Space Shuttle & Station Orbitals
Mesosphere –
Stratosphere –Jet Aircraft &Weather balloons fly
Troposphere – Water vapour & Dust Particles – Warmer upward
Explanation:
Thermosphere: The thermosphere is a layer of Earth’s atmosphere below the exosphere and above the mesosphere.It extends about 90 km to between 500 and 1000 Km The temperature is 200◦C. very hot in the day than night.
Mesosphere:It lies above the stratosphere and extend from 50 Km to 85 Km Jets and balloons do go high.
Stratosphere: It is second layer of the earth’s atmosphere starts above the Troposphere and ends 50 km above the ground.Ozone is abundant here which absorbs the UV radiation from the sun.
Troposphere:It is layer closes to the earth’s surface.It extends 7 -20km above the ground contains half of the atmosphere.All of the water Vapour and dust are in this layer.
