Answer 2

Answers of blanks:

• The Earth is the only planet that supports life.
• Nitrogen is the most abundant gas, constituting about 78% of the entire atmosphere.
• Ozonosphere(Ozone layer),protects the Earth from ultraviolet radiations of the Sun.
• The stratosphere extends upto 50 km above the Earth's surface.
• All the weather phenomena takes place in the troposphere layer of atmosphere.

Explanation:

The earth is in the only planet in the solar system which lies in the Goldilocks zone and have all suitable conditions for the survival of organisms. The Atmosphere is the thin layer of air around the Earth which protects our planet from harmful ultraviolet rays. Nitrogen is the most abundant gas found in the earth's atmosphere. Troposphere is the first and densest layer where all weather phenomena takes place. The Stratsophere is the next layer which extends upto 50 km. It contains ozone which absorbs the ultraviolet rays of Sun$.$

☃️ Let's know more facts on World geography(Atmosphere).

• Troposphere is the first layer of the atmosphere which lay nearest to the surface of Earth.
• It is the densest of all and all weather phenomenon occurs here. It is the responsible for the redness of sky during sunset and sunrise.
• Stratosphere is the next which is suitable for airplane flying. It contains the ozone layer, known as Ozonosphere.
• Next, Is mesosphere, where temperature decreases with height.
• The Thermosphere contains ions that reflect back ratio signals to earth. It protects the earth from harmful radiation.
• The last layer, Exosphere is the thinnest layer which is the gateway to the space. They also have concentration of ionized particles.
