Step-by-step explanation:

Scientists classify rocks into three different types. The main basis for the classification they chose is according to characteristics such as mineral , chemical composition, permeability, texture of the constituent particles and particle size.

Answer 2

Sedimentary rocks are formed from particles of sand, shells, pebbles, and other fragments of material.

Metamorphic rocks are formed under the surface of the earth from the metamorphosis (change) that occurs due to intense heat and pressure (squeezing).

Igneous rocks are formed when magma (molten rock deep within the earth) cools and hardens.
