GENERAL KNOWLEDGE

Detailed explanation-1: -Without the atmosphere, the solar radiation would heat the Earth during the day and escape during the night. Thus, if there were no atmosphere around the Earth, the Earth’s temperature would increase during the day and decrease during the night.

Detailed explanation-2: -Because the light from the Sun is refracted as it passes through the Earth’s atmosphere, the Sun is still visible after it is geometrically below the horizon and it is visible before it rises. So, if there were no atmosphere, no refraction would take place and hence, day time would decrease.

Detailed explanation-3: -The more carbon dioxide, the more the atmosphere warms due to the greenhouse effect. A warmer atmosphere holds more water vapor, which is itself a greenhouse gas. This is how water vapor triples the warming from increasing carbon dioxide and other greenhouse gases.”

Detailed explanation-4: -Temperature increases as you gain altitude in the stratosphere and the thermosphere. Temperature decreases as you gain altitude in the troposphere and mesosphere.
