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
What is the difference between exclusive and intrusive rocks?
There is no such thing as an "exclusive" rock. However, there are extrusive rocks. These are divisions of igneous rocks, or rocks that form from molten rock. Intrusive rocks form from molten rock that has cooled underground. They can also be called plutonic rocks. Extrusive rocks, also called volcanic rocks, form from molten rock that has formed at or above the surface.
What is the best clue to tell in extrusive igneous rocks from in instrusive igneous rock?
Extrusive igneous rocks have smaller crystals due to rapid cooling on the Earth's surface, while intrusive igneous rocks have larger crystals due to slower cooling beneath the Earth's surface. This difference in crystal size can help distinguish between the two types of rocks.
What is the extrusive equivalent of peridotite?
It's very rare to have an extrusive Peridotite, but under the right conditions Komatite can form. It's similar in appearance to Basalt, but has long ( anywhere between 1-10 cm) criss-crossing needles of olivine or pyroxene.
What is the similarities between intrusive and extrusive igneous rock?
Both are formed from the solidification of cooling magma.
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.
What is the major difference between intrusive and extrusive rocks is?
Extrusive means that the lava has come out and cooled on the surface. Intrusive means that the lava has cooled in the Earth i.e. underground.
Which one has large grains between intrusive and extrusive igneous rocks?
intrusive
What is the difference between the way intrusive and extrusive igneous is formed?
Intrusive igneous rocks cool beneath the crustal surface. Extrusive cool above the surface - pillow lavas cool below the sea but above the crust.
What is the difference between intrusive and intrusive?
What is the difference between intrusive and intrusive.
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 igneous rock and an extrusive rock?
instrusive is inside the valcano and exstrusive comes onto earth's crust
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.
What is the difference between an extrusive rock igneous rock and intrusive rock?
instrusive is inside the valcano and exstrusive comes onto earth's crust
What is the difference between intrusive and extrusive property of matter?
Intrusive properties of matter refer to characteristics that are exhibited within a substance, such as density or specific heat. Extrusive properties, on the other hand, pertain to features that are observed at the surface or interface of a substance, like color or texture.
What is the major difference between intrusive rocks and extrusive igneous rocks?
The major difference is their formation location: intrusive rocks are formed below the Earth's surface from the slow cooling of magma, resulting in coarse-grained textures, while extrusive rocks are formed on the Earth's surface from rapid cooling of lava, resulting in fine-grained textures. Intrusive rocks have larger mineral grains due to their slower cooling process, whereas extrusive rocks have smaller mineral grains due to their faster cooling process.
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).
