Answer:
(Layers of the (ordinal number
atmosphere). sequence)
Troposphere 1st layer
Stratosphere 2nd layer
Mesosphere 3rd layer
Thermosphere 4rth layer
Exosphere 5th layer
Characteristics/ description
Troposphere
It is characterized by decreasing temperature with increasing altitude. ... Weather occurs in the Earth's troposphere.
The layer of atmosphere closest to the surface is very important to life on the planet, and it is called the troposphere.
Stratosphere-
Ash and gas from a large volcanic eruption may burst into the stratosphere, the layer above the troposphere. Once in the stratosphere, it remains suspended there for many years because there is so little mixing between the two layers. Pilots like to fly in the lower portions of the stratosphere because there is little air turbulence.
Mesosphere-
The main characteristics of the mesosphere are its strong winds that go from east to west, the different atmospheric tides, the waves of atmospheric gravity that are inside, generally known as gravity waves, and finally its planetary waves.
Thermosphere-
It is located above the mesosphere and is the fourth layer of the earth. Its temperature changes with solar activity. In its interior sublayer i.e. ionosphere the radio waves are reflected. The boundary between the thermosphere and the exosphere is called Thermopause.
Exosphere-
The exosphere has gases like hydrogen and helium, but they are very spread out. There is a lot of empty space in between. There is no air to breathe, and it's very cold.
Altitude
Thermosphere
0-10km
stratosphere
10-30km
mesosphere
30-50km
thermosphere
50-400km
Exosphere
<400km
