The Moon (and the Earth, and all the other planets) are spherical, ball-shaped. There is only one Sun. So light streams outward from the Sun, and hits the Moon, and the Earth, and all the other planets, asteroids, moons, comets, rocks.... and everything else.
The point is that in this solar system there is only one Sun, one star - and the light comes from one direction. Only half of the Moon can be illuminated. (Actually, at the new moon, the ENTIRE Moon is lit up - half by the Sun, and the other half by reflected "earthshine" from the full Earth!)
Yes, but it is not always the same half. One complete day/night cycle on the moon
is 29.531 days on earth.
Any spot on the moon has the sun up in its sky and light for 14.7 Earth days,
followed by the sun down and not in the sky and darkness for the next 14.7
Earth days. The notable exception to this is, of course, craters at the lunar poles, the bottoms of which remain in perpetual shadow.
When you say "fully lit", remember that you're only looking at 1/2 of the moon's surface.
It's not possible for you to see more than 1/2 of the surface of a ball at any one time.
Try this . . .
Take a flashlight and a tennis ball into a dark room. Close the door
1). Notice that you cannot see the ball.
2). Turn on the flashlight and shine it at the ball.
3). Notice that the front half of the ball is lit up and the back half of the ball is in shadow.
4). Look at the side of the ball. Notice that what you see is 1/2 lit up and 1/2 in shadow.
5). Now think of the moon as a tennis ball, think of the sun as a flashlight, and think about
everything that you have just seen in the dark room.
Yes, half of the moon is always facing the sun. We only see different phases because of the angle at which we view it throughout every month.

EXCEPT DURING A LUNAR ECLIPSE!
Yes, how much of the moon we see lit up depends on the position of the moon compared to the sun.
When there is a new moon, although it appears that the moon is not lit up at all, the side of the moon facing away from earth is lit up.
At any moment, 50% of the moon is lit by the sun. But because the moon moves in a nearly-circular path around the earth, the amount of the lit-half that is visible from earth changes throughout the month.
When the moon is "in front" of earth, in the direction of the sun, we are looking up at the dark side of the moon, and we see none of it.
When the moon is "behind" the earth, in the opposite direction from the sun, we look up at the entire illuminated side of the moon, and we see a full disk.
With the moon in other positions, the portion of the lit-half that we can see is more or less, and the shape we see is somewhere in between nothing and a full disk.
Yes (except during a lunar eclipse.

The molten substances that appear at the surface of the earth is magma or lava
they continuously attack of wave under the cliff canes are formed.they sometime cuts the notch at the base of the surface.and when the notch grow the cliff fall and there appear a platform eroded at the base.wave some time change the surface of earth by the deposition of sand,mud and pebbles along the coast by shore drift.the soft rocks along the coastline is eroded by the continuous wave and bay are formed.but the hard rocks are not eroded and form capes.
Cosmic rays are continuously present in space - regardless of what day (or year) it is. Luckily, we are protected from cosmic rays on the surface of the Earth by the Earth's atmosphere and magnetic field. A small amount of comic rays can still reach the Earth's surface - particularly at higher altitudes.
Because it's surface is made up of mostly Iron Oxide (rust).

I think you are talking about global illumination, which is a rendering property under both mental ray and vray rendering engine. Global illumination is a term used to describe how light reflects off of diffuse surfaces, such as a wall, and illuminates other objects. For example, if you were to shine a light at a red wall in a dark room, the entire room will appear red as light is bouncing off of the wall. In both mental ray and vray, photons are used to simulate rays of light bouncing off of objects. You can google how to videos for rendering with global illumination for more info.

Not on a proper black surface (if one existed).
Appear, surface, arise.
Surface is a synonym for to appear. It begins with the letter S.
