Explanation
The correct answer is option 2 i.e. Gravitational force of Earth.
| Earth's Atmosphere | Earth's gravity is strong enough to hold onto its atmosphere. |
| It absorbs harmful ultraviolet radiation from the sun, helps keep Earth’s surface warm via the greenhouse effect, and reduces temperature extremes between day and night. | |
| Our atmosphere protects the Earth from the harsh rays of the sun and reduces temperature extremes, acting like a duvet wrapped around the planet. |
