Two types of igneous rock are intrusive (also called plutonic) and extrusive. There is also porphyry rock which is partly intrusive and partly extrusive. Porphyry rock has large crystals embedded in a mass of much smaller crystals. The large crystals formed underground as does intrusive rock, and were carried in lava when it erupted. The mass of smaller crystals formed around the large crystals when the lava cooled quickly above ground, as does extrusive rock.

What is igneous rock?
Igneous rock is a type of rock that forms from the cooling and solidification of magma or lava. It can be classified into two main types: intrusive (plutonic) igneous rock, which forms beneath the surface, and extrusive (volcanic) igneous rock, which forms on the surface. Examples include granite, basalt, and pumice.
What type of igneous rock hardens under the surface?
The type of igneous rock that hardens under the earths surface is called the Intrusive Igneous Rock. Intrusive Igneous Rocks are of two main types, Hypabasal and Plutonic. The plutonic forms at deeper depths.
Is igneous rock granite or basalt?
Both granite ans basalt are types of igneous rock.
What types of rock can be changed to a ingenious rock?
I think you mean igneous rock, not ingenious. Answer is none. Igneous rock can change to metamorphic rock.
What types of rocks are galina?
Igneous rock
What are the two types of crust and what type of rocks are they made of?
igneous rock and sedimentary rock
What are two main classifications of igneous rocks?
The two types of igneous rock are are intrusive and extrusive, depending on where they form. Intrusive igneous rock forms underground from slow cooling magma. Extrusive igneous rock forms at or near the surface from quick cooling lava.
What does extrusive rock means?
Extrusive igneous rock is one of two different types of igneous rocks. The other kind is intrusive igneous rock. Intrusive igneous rock is formed when magma in Earth's lithosphere cools and hardens. Extrusive igneous rock is formed when lava on Earth's surface cools and hardens.
What are two types igneous rocks?
Granite and basalt are the most common types of igneous rock. Igneous rock types, or classifications, also include those that are intrusive and extrusive. Intrusive igneous rock is formed from the solidification of slow cooling magma below the surface. Extrusive igneous rock is formed for the solidification of rapidly cooling lava at or near the surface.

Which rock category includes types of volcanic rock?
Igneous rock.
What two rock types are formed by transfer of heat?
Igneous an Metamorphic are the two types of rock that are formed with the help of heat .
Why is igneous rock called a mother rock?
Igneous rock is called a mother rock because it is the primary rock type from which all other rock types can form through the process of solidification and cooling. It serves as the starting material for the rock cycle, giving rise to sedimentary and metamorphic rocks.
