Where metal comes from?

 

 

Most metals are found inside rocks, at the bottom of the sea and even in the centre of the Earth. All over the world, there are rocks above the ground and under the ground. Inside these rocks are different types of metals.

It takes thousands of years for metals to form under the ground. Hot liquid rock, called magma, and other materials mix together. As the mix cools down, metals form inside rocks. A rock with plenty of metal inside it is called an ore. Sometimes they are pushed to the Earth’s surface by volcanoes.

 

 

 

 

Geologists are scientists who study rocks.

Metals are found all over the world. Some rocks only contain tiny amounts of metal, but others have large amounts. Digging up rocks is expensive so it is important for geologists to know where metals are found.
