Cloudy nights are wanner compared nights, because clouds mainly – (1) Absorb heat from the atmosphere send it towards earth (2) Prevent cold waves from the sky descending on earth (3) Reflect back the heat given by earth (4) Produce heat and radiate it toward earth

Description : Cloudy nights are wanner compared nights, because clouds mainly – (1) Absorb heat from the atmosphere send it towards earth (2) Prevent cold waves from the sky descending on earth (3) Reflect back the heat given by earth (4) Produce heat and radiate it toward earth

Last Answer : (3) Reflect back the heat given by earth Explanation: It is because the night side of Earth will radiate infra-red radiation (heat) back into space.

Clouds float in the atmosphere because of their – (1) low pressure (2) low density (3) low viscosity (4) low temperature

Description : Clouds float in the atmosphere because of their – (1) low pressure (2) low density (3) low viscosity (4) low temperature

Last Answer : (2) low density Explanation: The key to why clouds float is that the density of the same volume of cloud material is less than the density of the same amount of dry air. Just as oil floats on water ... it is less dense, clouds float on air because the moist air in clouds is less dense than dry air.

The clouds float in the atmosphere because of their low: (1) temperature (2) velocity (3) pressure (4) density

Description : The clouds float in the atmosphere because of their low: (1) temperature (2) velocity (3) pressure (4) density
