Transcript of Types of Rocks

Igneous Rocks
Examples of extrusive are pumice and basalt.
Sedimentary Rocks
The process by which sediments harden to form sedimentary rock is called lithification.

Example: Halite
Metamorphic Rocks

The word metamorphic means "Changed From."
Igneous Rocks
Formed when magma cools and hardens.

This process occurs on the earth's surface or underground.

Metamorphic Rocks
Made up of one or more minerals. Classified based on the way in which they are formed.
Types of Rocks
Igneous Rocks
The exact location of the formation of the rock determines the type of igneous rock it is.


When magma cools and hardens below the Earth's surface, an intrusive igneous rock forms.
Metamorphic Rocks
Formed under extreme pressure combined with heat over time.
Sedimentary Rocks
Rocks on earth are broken down by weathering.

The broken down particles are called sediments, carried away by streams and rivers. The particles stick together and form a larger structure.
When magma rises to the surface
of the earth and hardens, it forms
extrusive igneous rocks.
Extrusive- tends to be glassy in texture because their formation
occurs rapidly.
Igneous Rocks
The process of intrusive rock occurs
slowly so these rocks have a grainy
texture.
Examples: Granite
Metamorphic rock can originate not
only as igneous and sedimentary
rock but also to other types of metamorphic rocks.
Example: marble
