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.

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.
