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 not true:
- Observing one property is not usually sufficient to accurately identify minerals; multiple properties are often needed.
- Minerals can be identified by various properties, including but not limited to color and hardness, so color and hardness alone are insufficient for identification.
- Rocks are made up of minerals, not the other way around.
