a - (iii) The moon is a large rock which does not have light and air of its own. The moon surface is dry and barren and has lot of mountains and ditches. The ditches are created due to large rocks which fall on the moon's surface. These ditches are called craters. b - (v) Moon is the natural satellite of the earth. When the moon is between the earth and the sun, we cannot see its lighted portion at all. This is the new moon. When the moon is on the opposite side we can see the full lighted surface.
