There are three main types of rocks: igneous rocks, which form from cooled molten rock and can be volcanic or plutonic depending on the cooling rate; sedimentary rocks, which form from compressed and cemented sediments; and metamorphic rocks, which are formed from intense heat and pressure acting on pre-existing igneous and sedimentary rocks at depth in the Earth's crust.

6. Types of Rocks

7.  : Formed from the cooling of molten rock
 A. Volcanic igneous rocks
- formed from molten rock that cooled quickly
on or near the earth's surface.
B. Plutonic igneous rocks
- are the result of the slow cooling of molten
rock far beneath the surface.

9. -Formed in layers as the result
of moderate pressure on
accumulated sediments.

10.  -Formed from older "parent" rock
(either igneous or sedimentary)
under intense heat and/or pressure
at considerable depths beneath the
earth's surface.
