Maggie - What is the moon made of?

  1. if you had to make your best guess, you might say the moon was made from rock. And you would be right!

    The moon has a very thick outer layer, or crust, made of hard rock. On the surface lies lunar soil, known as regolith. Have you ever seen pictures of astronauts Buzz Aldrin and Neil Armstrong leaving footprints in regolith as they walked on the moon? This layer of dust is the result of countless asteroids, comets and meteorites that have hit the moon over the years. Like cosmic jackhammers, they have blasted hard moon rock to bits.

    Also included in the landscape of the moon are plenty of dead volcanoes. At one time, volcanic eruptions were a common occurrence, spewing molten lava. That lava is now hardened into a type of rock you may be familiar with: basalt. Basalt deposits are so massive on the moon that they appear as dark areas. In fact, the ''face'' of the man on the moon is made of enormous areas of basalt.
