Regolith

Regolith is like the blanket of rocks, dust and soil that covers the moon and other planets. It's like the skin on an apple.

When meteoroids hit a moon or a planet, they explode and create small pieces of rocks and dust. These small pieces of rocks and dust mix with the soil on the surface of the moon or planet over time. Then, this mixture is called regolith.

Regolith is important because it tells us lots of information about the place where it is found. Scientists can collect regolith samples and study them to learn about the history of the moon or planet.

For example, scientists can study regolith to learn about the moon's past volcanoes and meteorite impacts. Also, they can look for water in the regolith, which is important if people want to go to the moon or other planets one day.

In conclusion, regolith is like the blanket of rocks, dust and soil that covers the moon and planets, and it is very important because it tells scientists about the history of the moon or planet.
