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.
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.
What are rocks called when they cool from lava at Earth's surface?
Igneous rocks that cool from lava at Earth's surface are called extrusive or volcanic rocks. They have fine-grained textures due to rapid cooling. Examples include basalt and rhyolite.
Does extrusive have fine grain or coarse grain?
Extrusive igneous rocks generally have a fine grain texture. This is because they cool quickly on the Earth's surface, causing the minerals to form small crystals.
Molten rocks that cool at the earths surface are known as?
Lava.
Is feldspar extrusive?
Feldspar is not considered extrusive itself. Extrusive rocks like basalt and rhyolite can contain feldspar as a mineral component that crystallizes at the surface. Feldspar is more commonly found in intrusive rocks like granite, which cool and crystallize beneath the Earth's surface.
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 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.
How do you think magma turns into extrusive igneous rocks?

Why do rocks cool and crystallize?
Not all rocks do cool and crystallize, your question is meaningless.
How does metamorphic rocks turn into a igneous rocks?
If it finds its way dowm into the earths crust through rock cycle and then is melted and mixes together to form molten magma, it could re-erupt to the earths surface and form an extrusive igneous rock or cool and solidify within the earths crust as an intrusive igneous rock.

What are types of extrusive rock?
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?
Igneous rocks that cool quickly on the Earth's surface are called extrusive or volcanic rocks. Examples include basalt, obsidian, and pumice. These rocks have fine-grained textures due to their rapid cooling.
Some igneous rocks cool at the surface and some cool underground. What are the names of these two types?
Underground = intrusive/plutonic aboveground = extrusive/volcanic
