How are rocks different from minerals? a) rocks are a pure substance and minerals are all mixtures. b) rocks have no physical or chemical properties similar to minerals. c) rocks are made up of one or more minerals, but minerals are not made up of rocks. d) minerals are made up of at least two rocks, but rocks are not made up of minerals.

The answer is C) Rocks are made up of one or more minerals, but minerals are not made up of rocks.

Let's look into the options one by one:

A) Rocks are a pure substance and minerals are all mixtures.

-This is false.

-The fact is the exact opposite, where rocks are mixtures of minerals while minerals are pure substance. For example, granite, a type of rock, is composed of quartz, mica and feldspar.

B) Rocks have no physical or chemical properties similar to minerals.

-This is false.

-As rocks are formed by different types of minerals, often can you find the properties of rocks similar to minerals especially when one mineral component is high.

C) Rocks are made up of one or more minerals, but minerals are not made up of rocks.

-This is correct.

-Most of the rocks are made up of more than one type of minerals given the minerals are mixed together or produced during different formation. We can therefore see that minerals are not made up of rocks but a component of rocks.

For example, the granite mentioned from above is formed when intrusive volcanicity occurs, when the magma cools down, more than a type of minerals are formed, putting together forming granite.

D) Minerals are made up of at least two rocks, but rocks are not made up of minerals.

-This is false.

-As from above, minerals are not made up of rocks, while rocks are made up of minerals.

Therefore the answer is C) Rocks are made up of one or more minerals, but minerals are not made up of rocks.
