Yeh, well...This is one of the possible ends to the universe. It will turn cold and dark and everything will cease. But consider this--By the time our Sun goes out humans will be far different from what we are now as we are from the first cells to appear on Earth. So who knows?
Black holes don't emit any radiation (except for an insignificant amount of Hawking radiation). However, if matter falls onto a black hole, it will emit x-rays before it reaches the event horizon (the point of no return), as a result of an enormous acceleration.
The solar radiation that reaches the earths surface from the sun is called INSOLATION
Most of the solar radiation is absorbed when it reaches the surface of the earth. Some of the solar radiation is also absorbed in the atmosphere.
Radiation.
Radiation.
As water is cooled its density increases until it reaches about 4 C and then it decreases.
electro-magnetic radiation(sunlight)
It is done by radiation.
Solar radiation.
Electromagnetic radiation.
When the density reaches a high enough point
Cloud cover influences the amount of solar radiation that reaches Earth's surface because solar radiation cannot reach earth if there is tons of clouds blocking the way
