What size crystal do magma make?
it depends on if it is intrusive or extrusive (intrusive is below the earth and extrusive is at or above the earth) intrusive has a bigger crystal because it takes time to cool down.
Is an intrusive crystal bigger than an extrusive crystal?
Typically, intrusive crystals are larger than extrusive crystals because intrusive rocks cool slowly beneath the Earth's surface, allowing larger crystals to form, while extrusive rocks cool quickly at the surface, producing smaller crystals.
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 would you except the crystals in a intrusive rock to be larger than the crystals in a extrusive rock?
Minerals formed in intrusive rock cool more slowly than extrusive rock, which is closer to the surface. The longer cooling period allows more time for crystal formation.
Is it true that intrusive rocks have similar crystals than extrusive rocks?
No, intrusive rocks typically have larger crystals due to slower cooling within the Earth's crust, while extrusive rocks have smaller crystals or a glassy texture because they cool quickly on the Earth's surface. The cooling rate affects crystal size in igneous rocks.
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 size crystal do magma make?
it depends on if it is intrusive or extrusive (intrusive is below the earth and extrusive is at or above the earth) intrusive has a bigger crystal because it takes time to cool down.
How are intrusive rock different from with extrusive rocks?
Intrusive Rocks Intrusive rocks are characterized by large crystal that forms deep underground. Extrusive Rocks They are characterized by fine-grained textures because their rapid cooling at or near the surface.
Is an intrusive crystal bigger than an extrusive crystal?
Typically, intrusive crystals are larger than extrusive crystals because intrusive rocks cool slowly beneath the Earth's surface, allowing larger crystals to form, while extrusive rocks cool quickly at the surface, producing smaller crystals.
Which crystal can help identify as igneous rock as intrusive or extrusive?
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.
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).
Is graphite rock extrusive or intrusive?
GRAPHITE is a native mineral. It is metamorphic and it is effectively the highest grade of coal.
Write the difference between extrusive and intrusive igneous rocks?

Why would you except the crystals in a intrusive rock to be larger than the crystals in a extrusive rock?
Minerals formed in intrusive rock cool more slowly than extrusive rock, which is closer to the surface. The longer cooling period allows more time for crystal formation.
Is lava intrusive or extrusive?
Lava is extrusive, meaning it forms on the Earth's surface as a result of volcanic activity. It cools rapidly and solidifies quickly into volcanic rock, such as basalt or obsidian. Intrusive rock, on the other hand, forms below the Earth's surface from magma that cools slowly.
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.
Extrusive rocks which cool more rapidly than intrusive rocks generally have?
Extrusive rocks that cool more rapidly than intrusive rocks generally have a fine-grained texture with small mineral crystals. This rapid cooling prevents larger crystals from forming due to lack of time for crystal growth. Examples of such rocks include basalt and rhyolite.
