A volcano is composed of material that cooled and solidified at the surface, which makes it extrusive.

What are two types of igneous rocks?

Two types of igneous rocks are intrusive igneous rocks, which form from magma that cools and solidifies beneath the Earth's surface, and extrusive igneous rocks, which form from lava that cools and solidifies on the Earth's surface.


What igneous rock that formed from lava that erupted into earths surface are called?

When igneous rock forms on the Earth's surface, including on the ocean floor, it's called extrusive. It's called intrusive rock when it forms beneath Earth's surface, such as in mines.


Is a volcano a igneous rock?

Not necessarily. Igneous rock can be divided into two broad categories: intrusive rock and extrusive rock. Intrusive rock forms when molten rock cools and solidifies underground, so no volcanic activity is necessary. Extrusive rock forms above ground from molten rock that erupts from a volcano.


What is a intrusive volcano?

An intrusive volcano is a type of volcano that forms from magma that solidifies below the Earth's surface. The magma cools and hardens over time, forming intrusive rock formations such as dikes, sills, and batholiths. Unlike extrusive volcanoes, intrusive volcanoes do not result in eruptions or lava flows on the surface.


What kind of rock forms from the lava of an erupting volcano?

Igneous rock forms from the lava of an erupting volcano. This rock is created when molten rock cools and solidifies, either on the surface (extrusive igneous rock) or beneath the Earth's surface (intrusive igneous rock). Examples of igneous rocks include basalt, rhyolite, and granite.

What is the different between extrusive and intrusive rocks?

How do magma turn into extrusive igneous rock?

Lava can turn into igneous rock in 2 ways. When the lava cools to a hardening point inside the volcano it is called intrusive igneous rock. When lava cools outside of the volcano it is called extrusive igneous rock.

Is igneous rock produced by a volcano?

Not necessarily. Igneous rock can be divided into two broad categories: intrusive rock and extrusive rock. Intrusive rock forms when molten rock cools and solidifies underground, so no volcanic activity is necessary. Extrusive rock forms above ground from molten rock that erupts from a volcano.

When Magma is launched from a volcano forms what type of rock?

A volcano is made of extrusive igneous rock. The specific type of igneous rock will vary from one volcano to another.

How are igeneous rock formed?

Igneous rocks are formed by heat, pressure and cooling. They can be formed inside a volcano or outside a volcano. If they are formed outside the volcano the rocks are called extrusive igneous rocks, like basalt. If it is formed inside the volcano the rocks are called intrusive igneous rocks, like granite.


What kind of rock is formed after a volcano erupts?

Extrusive igneous rock such as basalt, rhyolite, pumice, and obsidian.


Are igneous rocks formed only beneath earth's surface?

No. Intrusive igneous rocks are formed beneath the earth's surface when magma cools and extrusive igneous rocks form when lava extrudes from a volcano and cools.
