The three correct statements about minerals are:
- Minerals are the components that make up rocks.
- Minerals are naturally occurring substances.
- Minerals are made of one element or one compound of elements.
The other statements are incorrect because:
- Observing one property is often not sufficient for identifying minerals, as many can share similar characteristics.
- Rocks are made up of minerals, not the other way around.
- Minerals can be identified by a variety of properties, not just color and hardness.
