What is the relationship between a mineral and a rock?

A.They are the exact same thing.
B.A mineral is a building block of rocks.
C.Minerals are only silicates while rocks are nonsilicates.
D.A rock is always man-made while a mineral is naturally occurring.

I think the answer is b?

To determine the relationship between a mineral and a rock, let's analyze each option:

A. They are the exact same thing.
This option is not correct. While minerals and rocks are related, they are not the same thing.

B. A mineral is a building block of rocks.
This option is correct. Minerals are the individual components or building blocks that make up rocks. Rocks are made up of one or more minerals.

C. Minerals are only silicates while rocks are nonsilicates.
This option is incorrect. While silicates (minerals containing silicon and oxygen) are the most common type of minerals in the Earth's crust, there are also many nonsilicate minerals. Rocks can contain both silicate and nonsilicate minerals.

D. A rock is always man-made while a mineral is naturally occurring.
This option is incorrect. Minerals are naturally occurring chemical compounds that form in the Earth's crust, while rocks are naturally occurring aggregates of minerals. Both minerals and rocks are naturally occurring.

Therefore, the correct answer is B. A mineral is a building block of rocks.
