The moon is much smaller and lighter than the Earth. Because of this, its force of gravity is much weaker, one sixth of the Earth's. So, our moon is unable to hold an atmosphere.
Why does the shape of the moon change?
The moon goes around the Earth. Sometimes we can see all or most of the part catching the sunlight , but sometimes we can see little or even none.
What are shadows on the moon?
The darkest shadows on the moon is where molton rock poured out onto it's surface long ago. The areas appear darker because they do not reflect sunlight as well as others do.
What early people imagined about the face of the moon!!
The Japanese thought it was a rabbit making rice cakes . Some Europeans thought it looked like a womam's face, other Europeans thought it looked like crab.
1. The moon is the only world, apart from the Earth, that people have actully walked on. Twelve U.S astronauts landed on the moon between 1969 and 1972 in the Apollo missions.
2. The moon always shows the same face to the Earth because it takes the same time for it to spin around once as it does for it to orbit the Earth.
3. The moon's suface is covered by craters caused by rocks, called meteorites, that crashed into it from space.
