Igneous Rocks Sedimentary Rocks And Metamorphic Rocks

Sedimentary rocks the result of deposition of fragments of rocks.

Formed by the cooling and hardening of magma molten rock from inside earth. Metamorphic they are formed through the change. Formed by the compaction and cementing of layers of sediment rock fragments plant and animal remains minerals from water. They often have large crystals you can see them with the naked eye.

Sedimentary rocks are formed by the accumulation of other eroded substances while metamorphic rocks are formed when rocks change their original shape and form due to intense heat or pressure. The rock cycle is a continuous process describing the transformation of the rocks through various stages throughout their lifetime. Igneous rock is formed when magma or lava from volcanoes cools. Formed by the effect of heat and.

Composed of calcite and clays. Igneous rocks solidified from magma and lava. Examples include basalt and granite. It usually has a whitish color.

Based on the mode of formation three major groups of rocks are defined. Igneous they form from the cooling of magma deep inside the earth. Composed mainly of calcium carbonate. There are many types of igneous rocks.

Composed of clastic debris in particles the size of clay and silt. There are 3 different types of rocks. Metamorphic rocks formed out of existing rocks undergoing recrystallisation. 2 igneous rocks are commonly found inside the earth s crust or mantle while sedimentary rocks are usually found in water bodies sea oceans etc.

Igneous rocks are molten rocks expelled as lava that has cooled and become solid. Igneous rocks comprise about 95 of the total earth s crust. Metamorphic rocks on the other hand are transformed rocks as a result of exposure to extreme heat and pressure beneath the earth s mantle. All other types of rocks viz sedimentary and metamorphic originate from igneous rocks and therefore they are also called primary rocks.

Each kind of igneous rocks contains different minerals and has different structures. Most igneous rock is very hard. Sedimentary rocks are generally formed by matter that has settled beneath lakes and ocean floors. The rock cycle simply moves from the igneous to metamorphic to sedimentary rocks and the process repeats itself over and over.
