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.
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 groups of rocks can igneous rocks be formed from?
igneous rocks are formed by magma reaching earths surface and cooling quickly to form extrusive igneous rock.another igneous rock is called intrusive igneous rock. it is formed when magma cools and hardens below the surface.
Intrusive igneous rock is cooled and solidified above ground?
False. Intrusive igneous rock forms underground when magma cools and solidifies slowly. Extrusive igneous rock forms when magma erupts onto the Earth's surface and cools quickly.
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.
How does magma from igneous rock?
magma cools to form igneous rock

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.
Magma cools and solidifies to form what rocks?
igneous rocks

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 rock forms when magma cools and hardens?
Igneous rock forms when magma cools and hardens. This type of rock can be classified as intrusive (plutonic) if it cools below the Earth's surface (slow cooling) or extrusive (volcanic) if it cools quickly on the Earth's surface. Examples of igneous rocks include granite, basalt, and obsidian.
Type of rocked formed when lave or magma cools?
A rock that is formed when magma cools is called a igneous rock.
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.
