Question

Which of the following is true about rocks?

Answer 1

Answer: D). Most rocks are a mixture of minerals

Rocks are the natural substances these are the aggregate of one or more number of minerals. These minerals are responsible for chemical and physical nature of rocks. These are responsible for type of particles, texture of particles and overall rock structure. Example of rock having mineral aggregate is granite which is a combination of minerals like quartz, biotite and feldspar.

Answer 2

Rocks are a mixture of minerals (D).

Further Explanation:

Minerals are made up of large element, most elements are simple substances that can not breakdown into any other substance.  

Most common example of minerals are Na,Si,Cl etc.

For example, SiO4  mineral contains large amount of element  

Rocks are aggregates of minerals, rocks are major of three types:

• Igneous Rocks
• Sedimentary Rocks
• Metamorphic Rocks

Igneous rocks are created when lava cools down and solidify in rock.

The metamorphic rocks are made by the subjection of igneous rocks and sedimentary rocks under high pressure and temperature.

The sedimentary rocks are created by continuous deposition of minerals, earlier rocks, and animal.

Example of igneous rocks are granite and made up of a mixture of element example SiO2 and Al2O3.  

Examples of sedimentary rocks are breccias and siltstone and of metamorphic rocks are marbles.
