Extrusive igneous rock forms when magma solidifies above ground (or under water). Intrusive igneous rock forms when magma solidifies underground.
Extrusive igneous rocks form on or near the Earth's surface from lava that has erupted from a volcano. Examples of extrusive igneous rocks include basalt and rhyolite.
Igneous rock is formed when hot magma from inside the earth meets the earth's outer crust and eventually cools to form one of the three different types of rock.

Lava cools to form?
Extrusive igneous rock.
What does extrusive igneous rock form from?
Extrusive igneous rocks form from lava that cools quickly on the Earth's surface, leading to fine-grained texture. Examples of extrusive igneous rocks include basalt and rhyolite.
What type of rock can be intrusive and extrusive?
Igneous rock can be both intrusive and extrusive. Intrusive igneous rocks form from magma that cools beneath the Earth's surface, while extrusive igneous rocks form from lava that cools on the Earth's surface. Examples of intrusive igneous rocks include granite and diorite, while examples of extrusive igneous rocks include basalt and rhyolite.
What kind of igneous rocks for on earths surface?
Some do. These are called extrusive igneous rocks. However a large portion of igneous rocks form beneath the surface. These are intrusive igneous rocks.
What is the most extrusive igneous rock?
Basalt is the most common extrusive igneous rock.

What is igneous rocks that form from magma that reaches the surface of the earth?
Extrusive Igneous Rock.
What is the similar in intrusive and extrusive igneous rock?
Igneous rocks which form by the crystallization of magma.

A lava flow is an example of an igneous rock one of the two main igneous rock groups?
It is an example of extrusive igneous rock.
What kind of rock is formed after a volcano erupts?
Extrusive igneous rock such as basalt, rhyolite, pumice, and obsidian.
What is the difference between igneous rocks and extrusive rocks?
Extrusive is a form of igneous rock - it's what you get when the magma is extruded or squeezed out onto the surface in the form of lava.
When melted rock erupts from a volcano and hardens what kind of rock does it form?
Extrusive igneous rock.
