(i) What is the atmosphere? Answer:
The blanket of air surrounding the earth
is called the atmosphere. The atmosphere primarily comprises nitrogen and oxygen in bulk and other gases like carbon dioxide, helium, ozone, etc in lesser quantities. All living beings on earth depend on the atmosphere for their survival.
Why is troposphere important for us Class 7?
Answer: Troposphere is the densest layer of atmosphere that is composed of water vapour, dust particles and many other impurities. Due to this thickness, troposphere
absorbs most of the heat radiated by the Earth’s surface, thereby, maintaining the temperature of the surface
.

Why is it called atmosphere?
An atmosphere (
from Ancient Greek ἀτμός (atmós) ‘vapour, steam’, and σφαῖρα (sphaîra) ‘sphere
‘) is a layer of gas or layers of gases that envelope a planet, and is held in place by the gravity of the planetary body. A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low.
What is atmosphere called?
The atmosphere is comprised of layers based on temperature. These layers are the
troposphere, stratosphere, mesosphere and thermosphere
