What Igneous rocks have large crystals and form when melted rock cools slowly and hardens underneath earth's surface?
They are called intrusive igneous rocks.
What are types of igneous rock?
igneous rocks are melted rocks and melted metal that cools quickly or slowly from a volcano and usually from magma.
When igneous rocks from a volcanic eruption cools what does it form?
When igneous rocks from a volcanic eruption cool, they can form either intrusive or extrusive rocks. Intrusive igneous rocks form when magma cools slowly beneath the Earth's surface, resulting in larger mineral grains. Examples include granite and diorite. Extrusive igneous rocks form when lava cools quickly on the Earth's surface, resulting in smaller mineral grains. Examples include basalt and pumice.
Do Glassy igneous rocks form when magma cools so slowly that mineral crystals cannot grow?
The "glassy" igneous rock is called obsidian, and it occurs when the magma cools very rapidly.
What are large grains of intrusive rock that cools down slowly?
Intrusive Igneous rocks. Examples: obsidian, magma

Where do coarse-grained igneous rocks form?
Coarse-grained igneous rocks are formed when magma cools slowly deep inside the Earth. Creating big crystals in them.
What igneous rocks form below Earths surface?
Igneous rocks that form below the Earth's surface are called intrusive igneous rocks. They crystallize when magma enters an underground chamber and cools very slowly.

Igneous rocks that form when magma cools on Earths's surface are called what igneous rocks?
Extrusive igneous rocks.
What Forms when molten rocks cools and hardens?
Igneous rocks
Where does in intrusive igneous rock form?
formed when molten rocks called magma becomes trapped in small pockets . As these pockets of magma cools slowly underground, the magma becomes igneous rocks
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
