Answer 1

Three points of significance of the Earth’s atmosphere are:

1. The atmosphere protects the Earth from harmful ultraviolet and infrared rays of the sun, which helps in safeguarding living organisms from harmful radiation.
2. It contains life-sustaining gases like oxygen and nitrogen, which are essential for respiration and other biological processes essential for life on Earth.
3. The atmosphere helps in retaining necessary warmth on Earth by absorbing heat and keeping the Earth warm at night, thus maintaining a stable climate and enabling the circulation of water vapor, which is crucial for rainfall and other weather phenomena.
