Are magmas classified as intrusive and extrusive?
Yes, magmas can be classified as intrusive or extrusive. Intrusive magmas cool and solidify beneath the Earth's surface, forming intrusive igneous rocks like granite. Extrusive magmas erupt onto the Earth's surface and solidify quickly, forming extrusive igneous rocks like basalt.
Is talc intrusive or extrusive rock?
Talc is formed from the metamorphism of magnesium-rich rocks, such as serpentinite. It is classified as a metamorphic rock, which means it is formed under intense heat and pressure deep within the Earth's crust. Therefore, talc is considered an intrusive rock.
Can rocks both have igneous and intrusive?
Rocks can be classified as either igneous or intrusive, but not both. Igneous rocks are formed from the cooling and solidification of magma (molten rock) above or below the Earth's surface. Intrusive rocks specifically form from magma that cools and solidifies underground, beneath the Earth's surface.
Is Jasper a Intrusive rock?

Are magmas classified as intrusive and extrusive?

What is rock type?
Granite is classified as an intrusive, felsic, igneous rock.
What are the main two types of igneous rocks?
Igneous rocks are classified as either extrusive or intrusive. Extrusive rocks form from lava at or above the ground, and intrusive rocks form from magma below the ground. Granite is intrusive, pumice is extrusive.
Can magmas be classified as intrusive or extrusive?
Yes, magmas can be classified as intrusive or extrusive. Intrusive magmas form underground as the magma cools slowly, resulting in large crystals. Extrusive magmas, on the other hand, cool quickly on the Earth's surface, leading to fine-grained or glassy textures like obsidian or basalt.
How igneous rock classified?
Geologists classify rocks by where they are formed; above ground or under ground
