How Is Basalt Formed? | Reference.com

Basalt is primarily formed by the extrusion of lava flows onto the surface of the earth during a volcanic eruption. The intrusion of a narrow sill or igneous dike below the crust also results in the formation of basalt. Basalt is a type of igneous rock that is typically dark in coloration with a fine-grained texture.

How Is Metamorphic Rock Formed? | Reference.com

Metamorphic rock is formed underground through a process that changes a rock's molecular structure due to pressure, heat and chemical reactions. A metamorphic rock forms from a parent rock called a protolith. Depending on conditions, a protolith can transform into any metamorphic rock.

What are igneous rocks? - USGS

Igneous rocks (from the Greek word for fire) form when hot, molten rock crystallizes and solidifies. The melt originates deep within the Earth near active plate boundaries or hot spots, then rises toward the surface. Igneous rocks are divided into two groups, intrusive or extrusive, depending upon where the molten rock solidifies.

Obsidian: Igneous Rock - Pictures, Uses, Properties

What is Obsidian? Obsidian is an igneous rock that forms when molten rock material cools so rapidly that atoms are unable to arrange themselves into a crystalline structure. It is an amorphous material known as a "mineraloid."The result is a volcanic glass with a smooth uniform texture that breaks with a conchoidal fracture (see photo).

Types of Intrusive Igneous Rock With Large Crystals ...

Intrusive igneous rock is formed from magma that cools beneath the surface of the Earth. This cooling process takes a very long time, on a scale of thousands or millions of years and produces a matrix of mineral crystal grains. This crystalline structure is large enough to …

Rock cycle - Simple English Wikipedia, the free encyclopedia

The rock cycle is the process by which rocks of one kind change into rocks of another kind.. There are three main kinds of rocks: igneous rock, metamorphic rock, and sedimentary rock.Each of these rocks can change into the other kinds by physical processes: cooling, melting, heat, weathering/erosion, compacting (squeezing tightly together), cementing, and pressure.

The Rock Cycle | National Geographic Society

There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming—that are part of the rock cycle. Sedimentary Rocks Sedimentary rocks are formed from pieces of other existing rock or organic material.

Pictures and Descriptions of Igneous Rock Types

Igneous rocks are those that form via the process of melting and cooling. If they erupt from volcanoes onto the surface as lava, they are called extrusive rocks.By contrast, Intrusive rocks are formed from magma that cools underground. If the intrusive rock cooled underground but near the surface, it is called subvolcanic or hypabyssal, and often has visible, but tiny mineral grains.
