Why unrives area are black |
|
Answer» There are two things to think about here. Let's take the EASY one first and ask "why is the daytime SKY blue here on Earth?" That is a question we can answer. The daytime sky is blue because light from the nearby SUN hits molecules in the Earth's atmosphereand scatters off in all directions. The blue color of the sky is a result of this scattering process. At night, when that part of Earth is facing away from the Sun, space looks black because there is no nearby bright SOURCE of light, like the Sun, to be scattered. If you were on the Moon, which has no atmosphere, the sky would be black both night and day. You can see this in photographs taken during the APOLLO Moon landings. |
