What is the effect of location on crystal size? Label the location of intrusive and extrusive igneous rocks on the diagram below. Then, illustrate the crystal size of the rock formed at that location in the appropriate callout circles.

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.
What is the difference between an intrusive and an extrusive igneous rocks?
"intrusive" means forced into something, "extrusive" means forced out onto the surface. The igneous magma reaching the surface is therefore extrusive , producing extrusive igneous rocks, and all the rest of the magma is intrusive, producing intrusive igneous rocks.
Is schist an intrusive or extrusive rock?
Neither, Igneous rock is either intrusive or extrusive. Thats what intrusive and extrusive is... A igneous rock.
Where are the two types of igneous rocks made?
Intrusive igneous rocks are formed beneath the Earth's surface through the slow cooling of magma, leading to larger crystal sizes. Extrusive igneous rocks are formed at the Earth's surface through the rapid cooling of lava, resulting in smaller crystal sizes.
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
Why is crystal size different between extrusive and intrusive igneous rocks?
Crystal size differs between extrusive and intrusive igneous rocks due to the rate of cooling. Intrusive igneous rocks, which form from magma that cools slowly beneath the Earth's surface, have larger crystals because the extended cooling period allows ions to arrange themselves into well-defined crystal structures. In contrast, extrusive igneous rocks form from lava that cools rapidly at the surface, resulting in smaller crystals or even a glassy texture due to insufficient time for crystal growth.
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.
Is marble an extrusive or an intrusive rock?
Neither. The terms intrusive and extrusive apply to igneous rocks; marble is metamorphic.
How does the rate of cooling influence crystal size of igneous rocks and how does that help you to distinguish between intrusive and extrusive igneous rocks?
The longer that magma is able to cool, the larger the crystals will be. Intrusive rocks will have larger crystals than extrusive rocks. For example granite (intrusive) has larger grains than rhyolite (extrusive).
What is the different between extrusive and intrusive rocks?
Intrusive: An intrusive igneous rock is formed from magma undergroundExtrusive: An extrusive igneous rock is formed from lava outside of the volcano.
Is a metamorphic rock intrusive or extrusive?
It is neither. Intrusive and extrusive are terms used to describe igneous rock.
Is extrusive a rock?
Igneous rocks can be categorized as either extrusive or intrusive.
