How does magma make a rock?
When magma cools and solidifies underground, it forms igneous rocks through the process of crystallization. As the magma cools, minerals within it begin to crystallize and solidify, creating the interlocking crystal structure that characterizes igneous rocks. The specific composition and cooling rate of the magma dictate the type of igneous rock that is formed.
What is the size of the blank in igneous rocks depends on how quickly or slowly the magma or lava cools?
The size of the crystals in igneous rocks depends on the cooling rate of the magma or lava. When magma cools slowly, typically beneath the Earth's surface, larger crystals form due to the longer time allowed for crystal growth, resulting in intrusive igneous rocks like granite. Conversely, when lava cools rapidly on the surface, smaller crystals form, leading to extrusive igneous rocks like basalt. Thus, the cooling rate directly influences the texture and crystal size of the resulting rock.
How and where are igneous rocks formed?
Igneous rocks are formed when molten magma cools and solidifies either beneath the Earth's surface (intrusive) or on the surface (extrusive). Intrusive igneous rocks are formed from magma that cools slowly underground, while extrusive igneous rocks are formed from lava that cools quickly on the surface.
What rocks forms when magm cools within th earth?
If the magma cools on the surface of the crust, it is called extrusive igneous rock, such as pumice, basalt or rhyolite. If the magma cools inside the crust, it is called intrusive igneous rock, such as granite.
What type of rock do volcanoes make?
Volcanoes primarily produce igneous rocks when magma erupts and cools. If the magma cools and solidifies beneath the Earth's surface, it forms intrusive igneous rocks, such as granite. If the magma erupts onto the surface as lava and cools quickly, it forms extrusive igneous rocks, such as basalt. The specific type of rock depends on the composition of the magma and the cooling conditions.
Why Is the crystal in igneous rock small if it cools quickly from magma?
The crystals within don't have as much time to grow when igneous rock is cooled more quickly as in extrusive igneous formation.
Do intrusive igneous rocks form when magma cools quickly?
Yes.
Is the crystal in the igneous rock large if it cools slowly from magma?
Yes. Slow cooling magma produces larger mineral crystals.
What does an igneous rock's crystal grain size indicate to the observer?
The size of the mineral crystals in an igneous rock is related to the rate of time spent in cooling from magma. Longer exposure to the crystallization temperature means larger crystals. Less time means smaller crystals, or in the case of obsidian, which cools extremely quickly, no crystallization.

What is the difference in crystal growth between intrusive and extrusive igneous rock?
The crystal growth of intrusive igneous is substantially more so than extrusive igneous. Magma cools quicker on the earth's surface, extrusive igneous formed, as opposed to below the crust, intrusive. Therefore the longer it takes to cool the magma, the more the crystal growth.
