What determines the mineral grain size in an igneous rock?
The cooling rate of the rock.
What controls the grain size of igneous rock?
The rate at which the igneous rock cools controls grain size. Slower cooling results in larger crystals while faster cooling results in smaller crystals.
What effect does a fast cooling rate have on grain size in igenous rocks?
Fast cooling lava or magma creates an aphanitic or small crystal (grain) textured igneous rock.
What type of rock forms due to heating and cooling?
igneous rock is formed by heating and cooling.
When magma is cooled it becomes what?
Cooling and solidifying magma turns into igneous rock.
What is the cooling rate of a coarse grained igneous rock?
Coarse grained igneous rock is formed from the slow cooling of magma.
How can an igneous rock become a metamorphic?
A metamorphic rock can become a igneous rock by melting and cooling
Rock formed by the cooling of magma?
igneous rock
What rock needs melting then cooling?
An igneous rock
Is an igneous rock formed by weathering?
No. Igneous rock forms from the cooling of molten material.
How is a rock from cooling lava classified?
a rock from cooling lava is called a extrusive igneous rock
What causes igneous rock to form?
Igneous rock is formed from the cooling and solidification of magma or lava.
