When continental plates collide, no subduction occurs as the plates are of similar buoyancy. However, the great amount of friction produced at the collision of plates causes the plates to fold and buckle, forming fold mountains.
It is friction between the moving plates as well as the build-up of sediments near the edges of the plates that causes mountains to be formed.
The moon only seems bright in the night sky because it is so close to the earth and because the trees, houses, and fields around you are so dark at night. In fact, the moon is one of the least reflective objects in the solar system.
