Write the difference between extrusive and intrusive igneous rocks?
igneous Extrusive is cool on the outside of the crust and cools quickly before crystal forms igneous Intrusive is cool on the inside of the crust and cools slowly and allowing crystal to form
When melted rock cools and hardens an intrusive igneous rock is formed?
when it cools undera lot of pressure underground it is an intrusive igneous. If it cools on the surface of the earth then it is an extrusive igneous.
What are the ways igneous rock can form?
intrusive igneous rock: magma cools and hardens in the earth and later forms an intrusive igneous rock. extrusive igneous rock: magma flows onto earth's surface and becomes lava. Then, lava cools and hardens above earth's surface and later forms an extrusive igneous rock.
What is the type of igneous rock formed beneath the surface of the earth?
Igneous rock formed from cooling magma below the surface is called intrusive igneous rock.
When igneous rocks from a volcanic eruption cools what does it form?
When igneous rocks from a volcanic eruption cool, they can form either intrusive or extrusive rocks. Intrusive igneous rocks form when magma cools slowly beneath the Earth's surface, resulting in larger mineral grains. Examples include granite and diorite. Extrusive igneous rocks form when lava cools quickly on the Earth's surface, resulting in smaller mineral grains. Examples include basalt and pumice.

Does an Extrusive Rock cool slowly?
Cools quickly, relative to intrusive igneous rock which cools slowly underground.
Is gabbro an intrusive or extrusive?
Intrusive Igneous Rock , it is because gabbro has a very rough texture.Intrusive cools slowly and extrusive cools rapidly.
When melted rock cools and hardens an intrusive igneous rock is formed?
when it cools undera lot of pressure underground it is an intrusive igneous. If it cools on the surface of the earth then it is an extrusive igneous.
What does extrusive rock means?
Extrusive igneous rock is one of two different types of igneous rocks. The other kind is intrusive igneous rock. Intrusive igneous rock is formed when magma in Earth's lithosphere cools and hardens. Extrusive igneous rock is formed when lava on Earth's surface cools and hardens.
What is the difference between igneous rock that cools above and igneous rock that cools below ground?
That depends on where it cools. Igneous rock forms from magma or lava (there's a difference!) cools and hardens. Extrusive igneous rock forms above the earth's crust, like when the lava from a volcanic eruption hardens. Intrusive igneous rock cools inside the earth when conditions change and the area around the magma cools allowing the magma to cool.
Igneous rock are classified based upon their?
There are two types of igneous rocks; intrusive and extrusive. Intrusive igneous rocks are formed underneath the earth's surface from magma where it cools slower and develops large crystal structures. Extrusive igneous rocks are formed above the earth's surface from lava that cools quickly and creates rocks with smaller, finer crystal structures.
Which rocks are extrusive igneous rocks where do they form?
Extrusive igneous rocks are formed when magma reaches the Earth's surface and cools. Since this magma is exposed to air and/or water, it cools very quickly, creating finer-grained, sometimes glassy rocks. Obsidian and pumice are both extrusive igneous rocks. Conversely, intrusive igneous rocks, like granite, are created when magma cools in the Earth's crust, which is a slower process.
What rocks cool from magma or lava?
magma cools into intrusive igneous rock while lava into extrusive igneous rock
What are the ways igneous rock can form?
intrusive igneous rock: magma cools and hardens in the earth and later forms an intrusive igneous rock. extrusive igneous rock: magma flows onto earth's surface and becomes lava. Then, lava cools and hardens above earth's surface and later forms an extrusive igneous rock.
What is the difference in crystal growth between intrusive and extrusive igneous rock?
The crystal growth of intrusive igneous is substantially more so than extrusive igneous. Magma cools quicker on the earth's surface, extrusive igneous formed, as opposed to below the crust, intrusive. Therefore the longer it takes to cool the magma, the more the crystal growth.
Why are the names intrusive and extrusive appropriate for the types of igneous rocks?
Because intrusive rock forms as magma cools below Earth's surface. Extrusive on the other hand, forms as lava cools on Eath's surface.
