The surface of the Moon has many things, such as craters, lava plains, mountains, and valleys. Scientists believe the craters were formed around 3.5 to 4.5 billion years ago by meteors hitting the moon's surface. The Moon does not have atmosphere, wind and weather that is why the footprints left there on the Moon by the Apollo astronauts will remain there for millions of years.
The Moon is not a light source. It mean that Moon does not make its own light. It reflects light from the sun. All of us can can see the Moon especially in the night because light from the Sun bounces off it back to the Earth. If the Sun wasn't there, we can not see the Moon.
The moon influences many of the tides in the oceans. This is because of the gravity force between the Earth and Moon. At full Moon and new Moon, the Sun, Earth and Moon are lined up, producing the higher than normal tides. When the Moon is at first or last quarter, it forms smaller neap tides.
