Which trait is common to minerals?
A. Commonly found in solid form
B. Share chemical composition with other minerals
C. Found deep in Earth’s core
D. Usually contain organic compounds
A. Commonly found in solid form
The trait that is common to minerals is A. Commonly found in solid form. Minerals are naturally occurring substances that are solid at room temperature and have a definite chemical composition.
The correct answer is A. Minerals are commonly found in solid form. To arrive at this answer, we can eliminate options C and D as they are not true for all minerals.
Option C states that minerals are found deep in Earth's core, but this is not accurate. While some minerals may be found in the Earth's core, the majority of minerals are found closer to the Earth's surface in various rocks and formations.
Option D suggests that minerals usually contain organic compounds, but this is also incorrect. Minerals are typically inorganic substances, meaning they do not contain carbon atoms bonded to hydrogen atoms, which is a characteristic of organic compounds.
To analyze option B, it states that minerals share a chemical composition with other minerals. While minerals can have similar chemical compositions, it is important to note that not all minerals share the exact same chemical composition. Therefore, option B is not a trait that is universally common to all minerals.
Finally, we are left with option A, which states that minerals are commonly found in solid form. This is a characteristic that is true for the vast majority of minerals. Minerals are solid, naturally occurring substances with a specific chemical composition and a crystalline structure.
Therefore, the correct answer is A. Commonly found in solid form.
