Greenhouse gases, like carbon dioxide, water vapor and methane capture the sun's radiation as it comes up from the surface of the earth. The molecules in the gases warm, and then radiate that heat out in all directions, including back down to the earth's surface. This is known as the greenhouse effect.
The ozone layer in the stratosphere acts as a blanket, bouncing the heat back at the the giver. (it absorbs a bit of the heat, too.)

The greenhouse effect.
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.

The Greenhouse Effect.
Greenhouse effect. The same effect that keeps Earth warmer than if there would be no atmosphere: without an atmosphere, the average temperature on Earth would be below zero Celsius.
The sun warms the earth. The heat (energy) from the earth then heats the air.
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.
The Greenhouse Effect.
The trapping of heat by the Earth's atmosphere is called the greenhouse effect. During the greenhouse effect, radiation becomes entrapped which results in the heating of the Earth.
The atmosphere of the earth holds the air we breath and protects us from the harmful effects of the sun. The atmosphere also holds heat so we don't freeze to death
This type of heat transfer is called radiation.
The Greenhouse Effect.
The atmosphere of Earth is a layer of gases surrounding the planet Earth that is retained by Earth's gravity. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night.
It is called the greenhouse effect
The process by which earth's atmosphere traps heat is called the greenhouse effect :)
