The geosphere is the layer that protects the earth from solar rays

It is false. The atmosphere is the layer that protects the earth from solar rays and not the geosphere.

There are four major subsystems that made up the earth. The subsystems are also referred to as “spheres of the earth”. The four subsystems are:

In all of the four major subsystems, the atmosphere is a layer that surrounds the earth and protects us from the solar system. It is mixture of gases that gets thinner till it reaches the space.

The atmosphere is made of nitrogen (78%), oxygen (21%) and other gases (1%). All the energy from the sun gets to the atmosphere and all the x-rays are also absorbed high in the atmosphere.  

There are five layers of the earth atmosphere and each of the layers is different from each other because of their various characteristics. The five layers include:

The mesosphere, stratosphere and thermosphere are the layers that block most of the energy UV radiations. They absolved harmful rays from the sun.

The first layer is the troposphere and it is above the earth surface. It also contains half of the earth atmosphere.

Exosphere is the upper limit of the earth atmosphere. It is basically the region where molecules and atoms escape into the space.
