Is biotite granite extrusive or intrusive?
Biotite granite is an intrusive igneous rock. It forms from the slow crystallization of magma deep within the Earth's crust, resulting in a coarse-grained texture.
Is glassy igneous rocks intrusive or extrusive?
Glassy igneous rocks are typically extrusive, meaning they form at the Earth's surface from rapidly cooling lava. Intrusive igneous rocks form underground from slowly cooling magma and generally do not have a glassy texture.
Is granite always intrusive?
Yes, granite is classified as an intrusive igneous rock, meaning it forms from the slow crystallization of magma beneath the Earth's surface. This process allows large crystals to develop, giving granite its characteristic coarse-grained texture. While other types of igneous rocks can be extrusive, such as basalt, granite is specifically associated with intrusive formations.
What features did you use to classify igneous rocks as extrusive or intrusive?
To classify igneous rocks as extrusive or intrusive, I focused on texture, mineral grain size, and cooling rates. Extrusive rocks, such as basalt, typically have a fine-grained texture due to rapid cooling at the Earth's surface, resulting in small or no visible crystals. In contrast, intrusive rocks, like granite, exhibit a coarse-grained texture with larger crystals formed from slower cooling beneath the surface. Additionally, the presence of gas bubbles in extrusive rocks can further indicate their formation from volcanic activity.
Example of intrusive rock?
Granite is an example of an intrusive rock. It forms when magma solidifies below the Earth's surface, resulting in a coarse-grained texture due to slow cooling. Intrusive rocks like granite are characterized by their large mineral crystals and are typically found in mountain ranges and continental landmasses.

What is the relationship between igneous rock's texture and where it is formed?
The relationship between an igneous rock's texture and where it was formed is that the texture depends on whether or not the rock is an extrusive rock or an intrusive rock. Those two different types of classifications for rocks tell you what the texture will be. For example, Intrusive rocks have a coarse-grained texture like granite and extrusive rocks have a fine-grained texture like basalt.

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.
Is schist an intrusive or extrusive rock?
Neither, Igneous rock is either intrusive or extrusive. Thats what intrusive and extrusive is... A igneous rock.
How can we tell if a rock is extrusive or intrusive?
To determine if a rock is extrusive or intrusive, examine its texture and grain size. Extrusive rocks, formed from lava that cools quickly on the Earth's surface, typically have a fine-grained or glassy texture with small crystals. In contrast, intrusive rocks cool slowly beneath the surface, resulting in a coarse-grained texture with larger, visible crystals. Additionally, the presence of gas bubbles in extrusive rocks can further indicate their formation from volcanic activity.
