Write short notes on sedimentary, igneous and metamorphic ...

Metamorphic rocks. Most metamorphic rocks are evolved from either sedimentary of igneous rocks. As rocks are compressed more and more by other layers of rocks, the lower rocks may change due to the weight of the upper layers. Heat from the interior of the earth may sometimes help to change the rock.

The Rock Cycle: Igneous, Sedimentary, and Metamorphic ...

The rock cycle is a continuous process describing the transformation of the rocks through various stages throughout their lifetime. The rock cycle simply moves from the igneous to metamorphic to sedimentary rocks and the process repeats itself over and over. Igneous rock can change into sedimentary rock or into metamorphic rock.

rock classification

There are three major classes of rocks, IGNEOUS, SEDIMENTARY, and METAMORPHIC, with the following attributes: IGNEOUS ROCKS form by crystallization from molten or partially material, called MAGMA . Magma comes mainly from two places where it is formed, (1) in the asthenosphere and (2) in the base of the crust above subducting lithosphere at a ...

Three Types of Rock: Igneous, Sedimentary & Metamorphic | AMNH

Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers. Metamorphic rocks result when existing rocks are changed by heat, pressure, or reactive fluids, such as hot, mineral-laden water. Most rocks are made of minerals containing silicon ...

Difference between Igneous, Metamorphic, and Sedimentary Rocks

Metamorphic rocks are usually found on the surface. Sedimentary rocks are generally formed by matter that has settled beneath lakes and ocean floors. These rocks are formed through years of sedimentation of dust, dirt, and other matter. Igneous rocks are good sources of mineral deposits such as tin, tungsten, and uranium.
