There isn’t only one type of rock you know! There are three different types.
Each rock has varying minerals which is why there are so many different ones.
Molten magma is the very hot stuff you find in volcanos! The magma turns to rock when it cools.
It is formed of layers from things such as sand, mud and small stones.
The pressure and heat can be made by the Earth’s movements. After all, it is moving all the time!
Geology is the study of rocks and Geologists are the people who study them!
Sometimes rocks from space land on Earth, however most of the time they land in the sea.
Some rocks are called ores. Ores are rocks that have metals like gold and silver on them.
Humans used them millions of years ago to build tools and weapons.
Did you know that rocks are found in some of the things we use at home?
