Igneous rock (derived from the Latin word ignis meaning fire) is one of the three main rock types, the others being sedimentary and metamorphic rock. Igneous rock is formed through the cooling and solidification of magma or lava. Igneous rock may form with or without crystallization, either below the surface as intrusive(plutonic) rocks or on the surface as extrusive (volcanic) rocks. This magma can be derived from partial melts of pre-existing rocks in either a planet's mantle orcrust. Typically, the melting is caused by one or more of three processes: an increase in temperature, a decrease in pressure, or a change in composition. Over 700 types of igneous rocks have been described, most of them having formed beneath the surface of Earth's crust.
Igneous rock is also known as volcanic rock or lava rock because it is most visibly formed from the cooling and solidification of molten magma or lava from a volcano.
Igneous extrusive rocks are called volcanic rocks, or just volcanics.

What is it called When melted rock becomes solid?
When melted rock solidifies, it forms an igneous rock. This process is known as crystallization.
When melted rock cools it forms?
When melted rock cools, it forms igneous rock. The process of cooling allows the molten rock, also known as magma or lava, to solidify and form crystals. Igneous rocks can have different textures and compositions depending on how quickly or slowly the rock cools.
Is the earth's crust sedimentary rock?
no it can also be metaphoric or igneous rock
Which terms best describe igneous rocks?
Calloused rock, or Subtraceaneal rock. Also, Ephyloceaeoulical-Pharchylogenic Carboniferincean Postulate Aggrevations is a fancy way of saying it.
When hot lava cooled and hardened it becomes?
When hot lava cools and hardens, it becomes solid rock known as igneous rock.
What is a Fire-rock?
A fire rock is also known as an igneous rock. Though it is called a fire rock it is actually made from hardened lava, not fire.
What is it called When melted rock becomes solid?
When melted rock solidifies, it forms an igneous rock. This process is known as crystallization.
When melted rock cools it forms?
When melted rock cools, it forms igneous rock. The process of cooling allows the molten rock, also known as magma or lava, to solidify and form crystals. Igneous rocks can have different textures and compositions depending on how quickly or slowly the rock cools.
What rock forms from cooling magma or lava from?
It is known as igneous rock.
What is the name of the type of volcanic rock formed below the surface of a volcano?
They are called Plutons, or plutonic igneous rocks, and are known as intrusive igneous rocks also.
What igneous rock is formed in the earth?
Igneous rock formed in the earths crust is known as intrusive rock. The magma that forms it cools slowly and therefore, creates rock with large crystals. An example of an intrusive igneous rock is granite.
What type of igneous rock is granite an example of?
There is a rock in Yosemite Park it is called Half Dome it is an igneous rock it is made out of granite
What is the defintition of igneous?
Igneous rock is one of the three main rock types based on the method of its formation. It is also referred to as plutonic or volcanic rock depending on where it formed. In a nutshell, to be classified as igneous, a rock must have crystallized and solidified from molten rock (magma) either below ground (intrusive igneous rock) or at or near the surface (extrusive igneous rock).
Is the earth's crust sedimentary rock?
no it can also be metaphoric or igneous rock
Which terms best describe igneous rocks?
Calloused rock, or Subtraceaneal rock. Also, Ephyloceaeoulical-Pharchylogenic Carboniferincean Postulate Aggrevations is a fancy way of saying it.
What type of rock can only be formed from sedimentary rock or igneous rock?
Metamorphic rock can form from igneous and sedimentary rock. It can also form from previously metamorphosed rock into a higher grade metamorphic rock.
When hot lava cooled and hardened it becomes?
When hot lava cools and hardens, it becomes solid rock known as igneous rock.
