Molten rocks that cool at the earths surface are known as?
Lava.
How do you think magma turns into extrusive igneous rocks?
When melted rock material cool's on earth's surface, it makes Extrusive Igneous Rock.
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
Is volcanic rock only igneous?
Lava is, by preferred definition, a viscous fluid comprised of molten rock that has reached the surface. In this case, lava is not an igneous rock. However, 'lava' can also refer to the cooled and solidified product of the molten rock. In this case, lava is an igneous rock, formed from the solidification of molten lava.
What is an igneous rock with small crystals?
If you're not looking for anything specific, any extrusive igneous rock will have smaller crystals, if any at all. This is because they cool quickly on the surface, leaving little time for crystals to form/grow.
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.
Igneous rocks that cool quickly on earth surface are?
Extrusive igneous rocks, like basalt, pumice, scoria, obsidian, and rhyolite.

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.

Some extrusive igneous rocks such as obsidian are glassy because they?
cool rapidly
How some extrusive igneous rocks such as obsidian are glassy is because they?
Cool rapidly
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 do intrusive rock have in common with extrusive rocks?
Sedimentary rocks are not classified by the terms intrusive or extrusive. These are terms used specifically for igneous rock classification, referring to rock that has formed from melt either below or on the surface.
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.
What rocks cool from magma or lava?
magma cools into intrusive igneous rock while lava into extrusive igneous rock
