The atmosphere moderates temperature changes, keeping the surface warm at night and cool in the day.
Without an atmosphere on Earth the temperature would probably go from about +100 degrees to -100 degrees every 24 hours. The atmosphere keeps it nicely within a range of ten degrees usually.
Carbon dioxide allows radiant heat through to the Earth's surface but blocks heat being radiated away from the surface which is at a relatively low temperature. So it produces a 'greenhouse' effect which raises the surface temperature, but only by a little at present.
On Venus, which has a 95% carbon dioxide atmosphere, the greenhouse effect has made the surface temperature 400-500 degrees C.
Greenhouse gases affect the temperature of the atmosphere. They capture the sun's heat and warm the planet.
Planet with an atmosphere, Venus. Planet without an atmosphere, Mercury (on the day side).
Mercury has not atmosphere, resulting in extreme temperature variations.
it warms up the planet
Research has shown that the planet Venus has its atmosphere temperature increased by the greenhouse effect
if we didn't have an atmosphere during the day our planet would be very hot and during the night our planet would be very cold
There are primarily two factors that affect the temperature of a planet.
Mercury
The composition of a planet's atmosphere is another important factor in determining its temperature. Greenhouse gases in the atmosphere, such as carbon dioxide and methane, trap heat from the planet's surface and contribute to the overall temperature.
There are a number of factors which affect the surface temperature of planets. First, there is sunlight which is a source of warmth. Then, there are various types of atmosphere, which retain warmth to varying degrees. Then, there is the radiation of heat into space, by means of infrared radiation, which happens on the side of the planet that faces away from the sun, and cools the planet.
Continental drift affect temperature and precipitation patterns around the planet by changing ocean currents
Jupiter(: <----WRONG! It is Mercury.
