To determine the correct answers about minerals, we need to apply some basic knowledge about minerals.
Firstly, minerals are naturally occurring substances, so the statement "Minerals are naturally occurring substances" is TRUE.
Secondly, minerals are composed of one element or one compound of elements. Therefore, the statement "Minerals are made of one element or one compound of elements" is TRUE.
Lastly, identifying minerals is not solely based on their color and hardness. Minerals have various properties, such as color, hardness, luster, streak, cleavage, and crystal form. Observing multiple properties is often necessary to accurately identify minerals. Hence, the statement "Observing one property is often the best way to identify minerals" is NOT true.
To summarize, the three TRUE statements about minerals are:
- "Minerals are naturally occurring substances."
- "Minerals are made of one element or one compound of elements."
The statement "Minerals can only be identified by their color and hardness" is FALSE.
