IGNEOUS ROCKS

By José Almarza

Igneous rocks are one of three main types of rocks and they divide into plutonic and volcanic igneous rocks.

Formation

Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. All magma develops underground, in the lower crust or upper mantle, because of the intense heat there.

SEDIMENTARY ROCK

By Jose Almarza

Types of rocks that are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface

FORMATION

Sediment form the surface deposits in a ocean or lake. The sediment deposited compacts the sediment below and pressses it together. The Materials in the sedient start dissolving in the water and glue the other sediments together

examples

- Coal - Sandstone

METAMORPHIC ROCK

By Jose Almarza

Any rock that results from the alteration of preexisting rocks in response to changing conditions, such as variations in temperature, pressure,

FoRMATION

Formed when a igneous or sedimentary rock is in extreme conditions like very high pressure and or very hot places.

-Marble -Slate
