Answer 1

Answer:

different types of rocks are:

Sedimentary rock:Sedimentary rocks are formed from particles of sand, shells, pebbles, and other fragments of material.(Together, all these particles are called sediment)

example-sandstone, siltstone

Metamorphic rock: Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form". The original rock is subjected to heat and pressure, causing profound physical or chemical change.

example-quartzite and marble.

Igneous rock:igneous rock, or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava.

example- granite, pegmatite
