How do fine- grained igneous rocks from?
extrusive igneous rocks =/
Where do fine grained igneous rock form?
Well that will be intrusive igneous rocks, extrusive forms inside the earths crust
Why are extrusive igneous rocks not coarse grained?
Extrusive igneous rocks cool quickly at the Earth's surface, which doesn't allow enough time for large mineral crystals to form. This rapid cooling results in fine-grained or glassy textures, making extrusive rocks not coarse grained.
What does extrusive igneous rock form from?
An extrusive igneous rock is when a volcano erupts and magma flows down, then cools, forming rocks.
Fine-grained extrusive rocks include all of the following EXCEPT . a. granite c. basalt b. scoria d. pumice?
Fine-grained extrusive rocks include basalt, scoria, and pumice, as they form from the rapid cooling of lava at the Earth's surface. However, granite is not a fine-grained extrusive rock; it is a coarse-grained intrusive igneous rock that forms from the slow cooling of magma beneath the Earth's surface. Therefore, the correct answer is a. granite.

What grain type is found in extrusive igneous rocks?
Extrusive igneous rocks are usually fine grained.
What are types of extrusive igneous rocks?
Extrusive igneous rocks are igneous rocks that form above earth's surface. They are usually fine-grained due to the rate in which they cool.
What is the crystal size for extrusive igneous rocks?
Fine grained
What are types of extrusive rock?
Extrusive igneous rocks are igneous rocks that form above earth's surface. They are usually fine-grained due to the rate in which they cool.
Which igneous rocks are fine grained to due to fast cooling?
Extrusive igneous rocks are fine grained due to fast cooling. They cool at a faster rate than most igneous rocks.
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.

Texture would be most unlikely to occur in an extrusive igneous rock?
A coarse-grained texture is unlikely to occur in an extrusive igneous rock because it forms quickly at or near the surface, limiting the time for large mineral grains to grow. Instead, extrusive igneous rocks typically have fine-grained to glassy textures due to rapid cooling.
