The temperature of the sun stays constant. At night, you are facing away from the sun, and the Earth is beyween you and the sun.
On a clear night, there are no clouds to trap heat near the Earth's surface, allowing it to radiate rapidly into space. This rapid cooling effect causes temperatures to drop more sharply compared to a night with cloud cover where the clouds act as a blanket, trapping heat and insulating the Earth.
Because the earth didn't have an atmosphere back then That answer is also right but their is another slip to it, the slip to it is that, their is a seasonal change in the atmosphere and if they didn't have a satellite the seasons wouldn't change, so that is also why we have satellites for electricity and the seasons...!
The Earth's rotation causes night and day to occur around the world. If it were not for the rotation, it would be night in one place forever and day in another place forever.
At night, the Sun's electromagnetic radiation does not reach the dark side of Earth. Therefore the atmosphere on Earth's night side emits more energy into space than it absorbs, so the air temperature increases. this is because of fronts
Green house effect assist the earth to retain its temperatuere in equilibrium. In absence of green house effect , earth's temperature will be rapidly increase due to intensity of sunlight further in night or in lake of sunlight the temperature of earth surface will be rapidly go down. But much concentration of green house gases absorb more heat that results much temperature during day and also more temperature in night...
Green house effect on average keep temperature of 35-40*c in day &20-25*c in night during summer season.
The temperature of the air falls at night because the earth loses heat by
The greenhouse effect (greenhouse gases in the atmosphere) keep the earth warm enough for life. They prevent some heat escaping out to space, particularly at night.
During the day, clouds can absorb heat energy from the sun. This causes a warming effect on the Earth. At night, cloud cover will keep the heat within the Earth's atmosphere, which also has a warming effect. This is because hot air rises, it is trapped by the clouds and therefore the temperature remains moderately warm. This is why in deserts (where there isn't much cloud cover) it is baking hot in the day, but freezing at night.
The sun warms the surface of the earth during the day. At night, especially a clear night, that heat rises from the earth into the atmosphere, lowering the temperature.
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 (the diurnal temperature variation).
oceans have a cooling and stabilizing effect so that the temperature of the earth can be kept under control. If Oceans are gone, the earth will experience a great difference between day and night. So hot during day, and so freezing during night.
The temperature of the sun stays constant. At night, you are facing away from the sun, and the Earth is beyween you and the sun.
Lower solar input & higher infrared radiation at night could decrease Earth's temperature.
That causes day and night. It also causes the Coriolis forces.
