Yes it does.
Greenhouse gases in the atmosphere absorb and retain infrared radiation (heat) from the surface of the earth.
Greenhouse gases.
The surface of the earth holds heat, and the greenhouse gases in the atmosphere hold heat all through the night. If the earth had no atmosphere, then at night all the heat would escape out to space and the earth would be freezing.
During a clear night, as heat absorbed by the earth during the day seeps out, the atmosphere allows the heat to pass through. During a cloudy night, however, the clouds catch and retain the heat in the atmosphere.Clouds trap heat being reflected from the earthThe heat radiation lost from the earth gets reflected by the clouds back to the earth, warming it. Whereas on a clear night it just escapes into space.
It does not, the night side of the planet loses (radiates) heat away into space. However, cloud cover and the presence of greenhouse gases in the atmosphere reflect some of this lost heat back to the planet surface, they act a s a blanket.
No atmosphere to retain heat

Greenhouse gases.
Clouds act as a kind of blanket for our atmosphere, trapping in heat. A clear night does not retain as much heat, so tend to be colder.

Nothing. Earth's atmosphere does not affect the sun. It does, however, cause Earth's atmosphere to retain more of the heat from the sun.
Compared to the external environment, a greenhouse will retain heat.
No, Mercury has no atmosphere. Without an Atmosphere planets cannot trap heat. This is the reason why Mercury's temperature changes drastically from day and night.
Yes, the absorption of UV rays by the ozone layer creates heat which forms the stratosphere, which gets warmer the higher you go.

The Moon has no protective atmosphere, as Earth does. On Earth, the atmosphere absorbs part of the heat, and moves it around.
