define rocks Explain types of Rock
Answers
Answer:
The three main types, or classes, of rock are sedimentary, metamorphic, and igneous and the differences among them have to do with how they are formed. Sedimentary rocks are formed from particles of sand, shells, pebbles, and other fragments of material. Together, all these particles are called sediment.
rock is a solid collection of mineral grains that grow or become cemented together. Some rocks are large while others are small. Small rocks are called pebbles. Every rock is made up of one or more minerals. Geologists (people who study rocks and minerals) classify rocks according to the way they are formed.
