How are metamorphic rocks formed underground?
when melted rock goes underground and magma cools, igneous forms
What kind of igneous rock is mafic and formed deep in the ground?
Gabbro is mafic and forms underground.
Is it extrusive rock that can have smooth texture because it is formed from lava that cooled so quickly that large crystals did not have time to form or is it intrusive?
Extrusive Igneous rock cools quickly above ground so it has a smooth texture so there isn't enough time for crystals to form and intrusive igneous rock forms inside a volcano or other underground hot place and takes longer to cool so crystals can form. It is extrusive.
When molten rock cools and solidifies what rock is formed?
Magma that cools underground forms igneous rocks.* It is called "lava" when it reaches the surface, and may solidify into several forms of igneous rock, depending on the compounds found in the magma and how it cools.
What type of rock can only form deeply underground?
Only an intrusive igneous rock forms underground, but you can argue that all metamorphism occurs underground. The issue here is that when the metamorphism is thermal, often the ground it is under has only just been formed (i.e. a lava flow). To avoid confusion, only regional metamorphism can take place underground. The rocks formed by regional metamorphism and intrusive magma cooling are rocks with crystalline texture.
How igneous rocks formed underground?
Igneous rocks are formed underground from a very hot substance called magma. As magma cools and hardens under extreme pressure, it forms igneous rocks.
What is the most familiar igneous rock that forms underground?
Granite

How can you tell that a rock is a igneous rock?
Well The Igneous Rock: When it Forms Underground the Pressure combines with Large crystals :)
What does term ''glassy'' mean when talking about igneous rock texture?
It pretty much forms from no crystallization. ;)
Igneous rock that cools very quickly when it forms may have a texture that is what?
smooth and shiny with no visible grain.
Igneous rock that cools very quickly when it forms may have a texture that is?
Smooth and shiny with no visible grain.
Igneous rock that cools very quickly when it forms may have a texture that is .?
Smooth and shiny with no visible grain.
What is the type of Igneous rock that forms underground?
Igneous, Metamorphic, and Sedimentary rocks
What kind of igneous rock is mafic and formed deep in the ground?
Gabbro is mafic and forms underground.
Which type of rocks forms from magma that cools deep underground?
Plutonic (intrusive) igneous rock
Can two igneous rocks be made of the same minerals but have different names?
Yes. The grain texture also matters. For example, basalt and gabbro have the same mineral composition, but basalt, which forms on the surface, has microscopic grains while gabbro, which forms underground, has larger mineral grains.
