Answer 1

Minerals are substances formed naturally in the Earth.  They have a definite chemical composition and structure. There are over 3000 minerals known.  Some are rare and precious such as gold and diamond, while others are more ordinary, such as quartz. Do you know of any more examples of minerals from the Earth?

Like all substances, minerals are composed of elements.

There are only about a hundred elements, and they are the basic building blocks of everything around us. They can be found either in their pure form or chemically combined with other elements to makecompounds.  A compound is two or more elements chemically joined together.
