The Moon’s surface not only has mountains, it also has rocks. Scientists found out that these moon rocks are similar to the igneous rocks on the Earth. They too are formed when molten lava solidifies after cooling down. But, their chemical make-up is different from that of the rocks found on Earth.
Moon rocks do not contain any traces of water. Much of the Moon’s surface is covered by tiny pieces of rocks, and dust. This is known as lunar soil.
It takes billions of years to form lunar soil. It is formed when large and small pieces of rocks rain on the surface of the Moon. Unlike the Earth, there is less iron on lunar soil.
