Is mount st helens intrusive?
No, Mount St. Helens is not an intrusive volcano. It is a stratovolcano, which is formed from explosive eruptions of viscous lava, ash, and other volcanic materials. An intrusive volcano forms when magma solidifies below the Earth's surface.
Why is a volcano an extrusive igneous feature rather than an intrusive feature?
A volcano is composed of material that cooled and solidified at the surface, which makes it extrusive.
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 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.

How are intrusive classified?
Intrusive features are typically classified as plutonic rocks, especially inside of a volcano. Comparatively, extrusive features are also classified as volcanic rocks.

Picture of volcano sill?
A sill is an intrusive body of magma that pushes its way between layers of sediments.
Volcanoes erupt hot liquid rock what type of rock is produced by volcanos?
Igneous rock... There are extrusive (formed on the exterior of a volcano by lava) and intrusive (formed on the inside of a volcano by magma).
What is the different between extrusive and intrusive rocks?
Intrusive: An intrusive igneous rock is formed from magma undergroundExtrusive: An extrusive igneous rock is formed from lava outside of the volcano.
