The area from the surface the ground towards the sky all over
the earth. These different type of gasses are present is called
atmosphere. This atmosphere consists of different types of layer
which are explained below. Layers of Atmosphere The atmosphere
the earth is divided into the following three layers. As shown
in the given diagram, the troposphere is the layer which starts
from the surface of the ground and reaches up to 10 miles above
the surface towards the conditions of the earth. This layer is
situated above the troposphere at and it is up to 30 miles from
the ground. This layer is composed of different gasses which are
heavier near the earth and lighter towards the sky. As shown in
the given diagram the layers of ionosphere is present above the
stratosphere and it is from 30 to 250 miles up from the ground.
This layer is composed of positive and negative ions. The
ionization of this layer is due to the heat energy of the sun.
This layer is located above the stratosphere. Its range is from
30 miles t
