What else can I help you with?
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?
Extrusive igneous rock is formed from rapidly cooled lava at Earth's surface. Examples are obsidian and basalt.
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?
Feldspars are a group of common rock forming mineralsthat can appear in all rock types. The term 'extrusive' is usually used to describe an igneous rock that has formed on or near the 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.
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.
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.
Why do rocks cool and crystallize?
Not all rocks do cool and crystallize, your question is meaningless.
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 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.
How does a metamorphic rock turn into a igneous rock?
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.

Under which condition below would you expect a coarse grained extrusive rock?
You would expect a coarse-grained extrusive rock when the magma cools and solidifies slowly underground, allowing larger crystals to form due to extended cooling time. This can happen in magma chambers or in deep-seated volcanic environments where the magma has more time to cool and crystallize before reaching the surface.
