Silicate minerals are the important rock-forming minerals as they are highly abundant in the earth's crust. They are also found in large quantities in the mantle. It is comprised of both silicon and oxygen, where the four oxygen atoms are linked to a Silicon atom at the center, forming a covalent bond. The rocks formed from this mineral are very hard and resistant.
The minerals such as potassium feldspar, amphibole, and quartz are comprised of a large amount of silicate minerals.
hey...im not sure about the answer but i think it is the 2nd option which is: rocks buried deeply and melted by intrusion rock erodedaway and deposited in ocea n base
Rock is a naturally occurring solid mixture of one or more minerals or organic matter.
<em><u>Rock is a solid mixture of crystals of one or more minerals, or organic matter.

<em><u>Rocks are classified by how they are formed, their composition, and texture. </u></em>Rock has been an important natural resource as long as humans have existed.
The rock cycle is the series of processes in which a rock type changes from one type to another.
