Intrusive igneous rocks are formed by slow cooling magma below the earth's surface. Extrusive igneous rock is formed by magma cooling quickly, at or near the surface.

What kind of rock forms when magna cools and solidefies in the Earth?
It depends on the composition of the magma, how quickly it cools and crystalises, the temperature and pressure of the original melt.
What is a type of crystal grain that forms when rock cools Slowly?
When molten rock cools slowly, it will have a lot of time to form crystals, so the crystal size will be quite big. Take granite, for example. With the naked eye, you can see the individual crystals. The grain size is quite large. The kind of mineral that forms is dependent on the composition of the magma.
Does magma beneath the surface cool fast?
Magma cools down about a week or so it is extremely hot about 350 degrees Fahrenheit , when it cools down it turns into crystals which are inorganic, naturally, solid, and having a atom arrangement.
What kind of rocks are formed when the magma cools beneath earth's surface?
Intrusive igneous rock.
What kind of rock does magma form when it hardens?
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 kind of mineral does magma form when it cools?
When magma cools, it forms igneous rock.
Where did gabbro come from?
Gabbro forms from a magma that is rich in iron and magnesium, and poor in silica (quartz). The magma cools and crystallizes deep below the earth's surface. Gabbro is from the same kind of magma as basalt and diabase, but because it cools more slowly, it develops larger crystals.
What kind of rock forms from magma that cools below the earth's surface?
Intrusive Igneous Rock.
What kind of rock forms when magna cools and solidefies in the Earth?
It depends on the composition of the magma, how quickly it cools and crystalises, the temperature and pressure of the original melt.
What type rock forms when magma cools and hardens?
Igneous Rock is formed when magma cools and hardens. It depends on whether it cools above ground or under ground for the size of the mineral crystals forming inside it.
What is a type of crystal grain that forms when rock cools Slowly?
When molten rock cools slowly, it will have a lot of time to form crystals, so the crystal size will be quite big. Take granite, for example. With the naked eye, you can see the individual crystals. The grain size is quite large. The kind of mineral that forms is dependent on the composition of the magma.
When lava flows and cools on Earth's surface it forms what kind of rock?
Igneous rock is formed through the cooling and solidificatio of magma or lava.
Does magma beneath the surface cool fast?
Magma cools down about a week or so it is extremely hot about 350 degrees Fahrenheit , when it cools down it turns into crystals which are inorganic, naturally, solid, and having a atom arrangement.
When magma cools rapidly what kind of textures does rock have?
Aphanitic, or fine-grained.
What kind of rock is formed when magma or lava cools and hardens?
Igneous rock is formed.
What kind of rocks are formed when the magma cools beneath earth's surface?
Intrusive igneous rock.
What kind of rock forms from magma?
igneous rock
