Does granite form on top of the crust?
No. Granite forms underground in the crust. If granitic magma reaches the surface and cools it forms a rock called rhyolite.
What type of rocks form when melted rock cools from inside the Earth?
Igneous rock forms when melted rock (magma) from inside the Earth cools.
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.
What is the difference between igneous rock that cools above and igneous rock that cools below ground?
That depends on where it cools. Igneous rock forms from magma or lava (there's a difference!) cools and hardens. Extrusive igneous rock forms above the earth's crust, like when the lava from a volcanic eruption hardens. Intrusive igneous rock cools inside the earth when conditions change and the area around the magma cools allowing the magma to cool.
What kind of mineral does magma form when it cools?
When magma cools, it forms igneous rock.
Write the difference between extrusive and intrusive igneous rocks?
igneous Extrusive is cool on the outside of the crust and cools quickly before crystal forms igneous Intrusive is cool on the inside of the crust and cools slowly and allowing crystal to form
Is pumice a rock that cooled slowly inside Earth's crust?
No. Pumice cools very rapidly above the surface. It is a glassy rock. Glass forms when lava cools too quickly for crystals to form.
What do ingeous rocks form from?
a type of rock that forms when magma cools and hardens very slowly deep in earths crust...
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.
When lava cools rapidly a crust forms on the surface of the flow If the low continues the crust wrinkles and forms volcanic rock known as what?
Pahoehoe.
What is intrusive?
Intrusive activity is when magma in the mantle or crust starts to cool and crystallize. Igneous rock forms from the crystallization.
Does granite form on top of the crust?
No. Granite forms underground in the crust. If granitic magma reaches the surface and cools it forms a rock called rhyolite.
What rock forms when melted rock from inside the earth cools and hardens?
Plutonic (or intrusive) rock forms when melted rock from inside the earth cools and hardens. The larger it cools down there, the bigger its crystals will be.
Is a new ocean crust formed at a divergent boundary?
because the molten rock cools in the water and forms a oceanic crust
What is an enormous gap that forms as new ocean crust cools and moves apart?
A rift.
What type of crystal grain forms when magma cools slowly?
the crystals are large
What type of crystals grain that forms when molten rock cools slowly?
Quartz
