The three correct statements about minerals are:
1. Minerals are naturally occurring substances.
2. Minerals are the components that make up rocks.
3. Minerals are made of one element or one compound of elements.
To arrive at these answers, we can eliminate the options that are incorrect.
The statement "Minerals can only be identified by their color and hardness" is false. While color and hardness can be useful in identifying some minerals, there are other properties like luster, cleavage, streak, and specific gravity that can also be observed to identify minerals.
The statement "Rocks are the components that make up minerals" is also false. Minerals are the components that make up rocks, not the other way around. Rocks are composed of different minerals mixed together.
Eliminating these two incorrect statements leaves us with the three correct statements mentioned earlier.
