What are two types of igneous rocks?
Two types of igneous rocks are intrusive which is found in a volcano. And extrusive which is found outside of a volcano.
What igneous rock that formed from lava that erupted into earths surface are called?
When igneous rock forms on the Earth's surface, including on the ocean floor, it's called extrusive. It's called intrusive rock when it forms beneath Earth's surface, such as in mines.
Is a diamond an intrusive or extrusive igneous rock?
A diamond is a mineral not a rock but I guess it extrusive because it happens pretty close to the surface of a volcano.
What is a intrusive volcano?
Intrusive is a geologic term used to describe igneous rock that has solidified from magma underground. Extrusive igneous rock refers to rock that has solidified from lava above ground.
Is a volcano a igneous rock?
Not necessarily. Igneous rock can be divided into two broad categories: intrusive rock and extrusive rock. Intrusive rock forms when molten rock cools and solidifies underground, so no volcanic activity is necessary. Extrusive rock forms above ground from molten rock that erupts from a volcano.
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.

How do magma turn into extrusive igneous rock?
Lava can turn into igneous rock in 2 ways. When the lava cools to a hardening point inside the volcano it is called intrusive igneous rock. When lava cools outside of the volcano it is called extrusive igneous rock.

Can a sedimentary rock be directly transformed into a igneous rock?
Yes, by heat and pressure. It could turn into two types of igneous rocks: intrusive and extrusive. An intrusive igneous rock is formed by heat from a volcano. It is cooled slowly, and has big crystals. An extrusive igneous rock is formed outside a volcano. It cools slowly and has small/ not visible crystals. So basically, if the sedimentary rock gets into a volcano, it can turn into an igneous rock. Hope that answered your question.
Is igneous rock produced by a volcano?
Not necessarily. Igneous rock can be divided into two broad categories: intrusive rock and extrusive rock. Intrusive rock forms when molten rock cools and solidifies underground, so no volcanic activity is necessary. Extrusive rock forms above ground from molten rock that erupts from a volcano.
When Magma is launched from a volcano forms what type of rock?
A volcano is made of extrusive igneous rock. The specific type of igneous rock will vary from one volcano to another.
Distinguish between andesite and diorite using two physical properties of igneous rocks?
Diorite is an intrusive which is formed inside of a volcano. Andesite is an extrusive which is formed outside of a volcano.
How are igeneous rock formed?
Igneous rocks are formed by heat, pressure and cooling. They can be formed inside a volcano or outside a volcano. If they are formed outside the volcano the rocks are called extrusive igneous rocks, like basalt. If it is formed inside the volcano the rocks are called intrusive igneous rocks, like granite.
