Question

Atmosphere is classified into different zones, which of the following is not among this classification?
A. Ionosphere
B. Ozonosphere
C. Lithosphere
D. None of these

Answer 1

Hint: The atmosphere is the sheet of gases which surrounds the Earth which is held near the Earth's s surface by gravitational attraction.

Complete Answer:
Looking at the given options :
Option a: The ionosphere is a very powerful part of the atmosphere. It grows depending on the energy it consumes from the Sun. It is called the ionosphere because of the presence of ions in this layer. As the ionosphere is composed up of charged atoms, it's uniquely reactive to the altering magnetic and electric conditions in space. This option is incorrect.
Option b:Ozonosphere is a layer in the stratosphere that includes a concentration of ozone adequate to block most ultraviolet radiation from the sun. About 90% of ozone layer is found in the stratosphere. The stratospheric area with the highest ozone concentration is generally known as the “ozone layer” . The ozone hole is seen maximum near Antarctica. This option is incorrect.
Option c: The lithosphere is the outer part of the Earth which comprises of three main layers: crust, mantle and core. The upper part of the lithosphere is made up of mantle and the crust, the exterior layers of Earth's structure. Lithosphere is vital for life to exist. This option is correct.
Option d: This option is incorrect and irrelevant.
Hence, the correct answer is option, ‘C. Lithosphere’.

Note:
- Svante Arrhenius is known as the father of atmosphere.
- Troposphere is the most crucial layer of the atmosphere. It is very crucial for the validity of life on earth as it results in the cloud formation, raining and retaining the heat balance of the earth.
