When magma cools down it forms a type of rock called igneous rock. Igneous rock can cool inside the earth or it can cool after it has come out on the earth's surface. When it is formed inside it is called intrusive but when it is on the earth's surface it is called extrusive.

What happens when magma rises to the surface?
It cools and solidifies into a sedimentary rock.
When magma cools too fast what happens to the size of the crystals?
When magma cools fast, crystals are small.Less time to form crsytalsWhen magma cools slow, crystals are large.More time to form crystalsWhen magma cools very fast, crystals do not form; nothing.Very less time to formWhen magma cools very slow, large crystals form; a LOT.A lot more time to form
What is determined by how magma cools and where it cools?
Its texture.
Is magma cools faster than magma?
No, magma is located in the volcano when it comes out it is called lava. Lava cools after it comes out. Magma is still heated as the volcano is.
Is lava magma when it cools down?
No. Lava is magma that has reached the surface.
What happens to magma as it cools?
It forms igneous rock.
What happens to magma to form igneous rock?
it cools
What happens when magma reaches the surface and cools?
it forms igneous rocks
What happens if magma cools?
Large and coarse textured minerals are formed.

What happens if magma cools slowly?
Large and coarse textured minerals are formed.
What happens after magma cools?
It turns into rock. Islands can be created by the newly formed rock.
What is magma and what happens when it cools down underground?
There are two known processes by which magma ceases to exist: by volcanic eruption, or by crystallization within the crust or mantle to form a pluton. In both cases the bulk of the magma eventually cools and forms igneous rocks.
Extrusive igneous rocks form when hardens and cools.?
It happens when lava is on the outside the cools down to form EXtrusive rock.
How do rocks solidify from molten magma?
The same way any solid forms from a liquid - the liquid magma cools off and becomes solid. This usually happens when the magma comes to the cooler surface of the earth as lava, but it can occur very slowly inside of the earth as the magma gradually cools.
How are mineral formed by crystallization from magma?
As magma cools, elements combine to form minerals.
