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.
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.
What are the major intrusive features created by volcano?
Major intrusive features created by volcanoes include dikes (vertical sheets of magma that cut across pre-existing rock layers), sills (horizontal sheets of magma that intrude between rock layers), and plutons (large igneous bodies that crystallize deep underground). These intrusive features are a result of magma intruding into the Earth's crust and solidifying before reaching the 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.
Compare and contrast dikes sills batholiths and volcano necks?
Dikes, sills, and volcano necks are intrusive igneous features formed from magma that solidified beneath the Earth's surface. Dikes are vertical or near-vertical intrusions, sills are horizontal intrusions, and volcano necks are vertical conduits that fed ancient volcanoes. Batholiths are large, deep-seated intrusive bodies that often form the cores of mountain ranges. They are generally larger in size and represent a more massive intrusion compared to dikes, sills, and volcano necks.
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.
Do laccolith features occur when volcano lava cools at the surface?
No. A laccolith is an intrusive feature.
Are intrusive igneous rocks formed after a volcano?
no there are wood roks made out of a volcano
How are intrusive features classified?
Intrusive features can be classified based on various characteristics such as their composition (rock, mineral, or fossil), size (small or large), shape (roundish or angular), and mode of formation (volcanic, tectonic, or sedimentary). These features may also be categorized according to their relationship with the surrounding rock or terrain, such as whether they cut across existing structures or postdate certain events.

What are 3 ways extrusive and intrusive different?
Intrusive rocks are from the magma INSIDE of the volcano. Extrusive rocks are from the OUTSIDE of the volcano. I don't know 2 other ways but by the way I learned this in 4th grade?!
How does extrusive differ from intrusive?
Extrusive rocks form from lava cooling on the Earth's surface, leading to rapid cooling and fine-grained texture. Intrusive rocks form from magma cooling beneath the surface, resulting in slower cooling and coarse-grained texture. This difference in cooling rates gives extrusive rocks their characteristic fine-grained appearance and intrusive rocks their coarse-grained appearance.
What is a volcano dike?
an intrusive body of magma that cuts across layers of rock
