Igneous: meaning, definitions and examples

rock type

Igneous refers to a type of rock that is formed through the cooling and solidification of magma or lava. This process can occur either beneath the Earth's surface, where the rock is termed 'intrusive' or 'plutonic,' or on the surface, where it is known as 'extrusive' or 'volcanic.' Igneous rocks are characterized by their crystalline texture, which differs depending on the rate of cooling. Common examples of igneous rocks include granite, basalt, and pumice. The properties of igneous rocks make them vital in various geological processes and construction.

crystalline, magma-derived, volcanic

Examples of usage

• Granite is an igneous rock used in countertops.

• The volcanic eruption created new igneous formations.

• Many geological studies focus on igneous activity.

• Igneous rocks provide insights into the Earth's mantle.

• The texture of igneous rocks can vary significantly.
