Molten rocks that cool at the earths surface are known as?
Lava.
Which rocks cool much faster extrusive rocks or intrusive rocks?
Extrusive rocks cool much faster than intrusive rocks. This is because extrusive rocks form from lava that erupts onto the Earth's surface, where it cools quickly in contact with air or water. In contrast, intrusive rocks crystallize from magma that cools slowly beneath the Earth's surface, allowing larger crystals to form. Thus, the cooling rate is significantly faster for extrusive rocks compared to intrusive ones.
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.
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.
Which rocks cool much faster extrusive rocks or intrusive rocks?
Extrusive rocks cool much faster than intrusive rocks. This is because extrusive rocks form from lava that erupts onto the Earth's surface, where it cools quickly in contact with air or water.

Thus, the cooling rate is significantly faster for extrusive rocks compared to intrusive ones.
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.

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.
Why do rocks cool and crystallize?
Not all rocks do cool and crystallize, your question is meaningless.
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.

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.
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.
