Igneous rocks are formed when magma does what?
The Igneous rock formed when magma cools are; 1. Extrusive (Volcanic) Igneous Rock; which are igneous rocks formed when magma cools outside the earths crust. The texture of of extrusive igneous rock is fine grained. 2. Intrusive (Plutonic) Igneous Rock; these are igneous rocks formed by gradual cooling of magma within the earths crust. The texture is coarse grained.
What is molten rock when it is in and outside of the Earth's crust?
Igneous Rock
What does a fine-grained igneous rock form from?
A fine grained igneous rock forms from Lava that escapes from the earth crust to the surface and cools and solidifies rapidly.
What are igneous rocks that form on lava?
Extrusive igneous rock, like basalt and rhyolite.
Is intrusive igneous rock such as granite date from when it cools deep within the Earth's crust or is the date given as when the rock is uplifted through the Earth's crust?
It is dated from the time it solidifies as rock.
What is one igneous rock that is made outside of earth's crust called?
Extrusive (volcanic) igneous rock. An example is Basalt.
What does a fine-grass igneous rock forms?
A fine grained igneous rock forms from Lava that escapes from the earth crust to the surface and cools and solidifies rapidly.
How metamorphic rock turns into igneous?
Metamorphic rock becomes igneous rock when it is melted, then solidifies.
When molten rock hardens and solidifies which type of rock is formed?
When molten rock solidifies it forms igneous rock.
What is igneous rock formed in the Earth's crust?
Igneous rock is formed when molten magma cools and solidifies within the Earth's crust. This process can happen either beneath the surface, leading to intrusive igneous rocks, or above the surface, resulting in extrusive igneous rocks like basalt.
What igneous rock formed from lava have a fine?
Volcanic (Extrusive) igneous rock, which are formed by lava that comes out of the earths crust, then cools and solidifies rapidly on the earths surface due to exposure to the environmental atmosphere.
What is the material that igneous rock is made of called?
Igneous rock is formed from the crystallization of molten magma or lava. Intrusive igneous rock is formed beneath Earth's crust from magma. Extrusive igneous rock is formed above Earth's crust from the crystallization of lava.
