Underwater volcanoes can be as bad as the ones on top, because they can split the earth just like it did to Pangea. What is Pangea? Well its was a large continent made up with the continents today and it was a big continents until plate tectonics. It was here from thousands, millions, and billions of years ago. I hope it answered your question and i hope it wasn't wrong!!

What cools quickly on the earth's surface?
it would be lava , magma is in the ground and flows on earths surface and cools to lava
What does magma need to do for a rock to form?
Magma is basicaly the same as lava, except magma is still in the volcano, when magma has come out of the volcano, it has become lava.
How do minerals form from magma and lava?
well lava and magma are pretty much the same thing but the way minerals form from lava and magma is that when a volcano erupts the magma turns to lava and lava is just magma that cool-es faster because it is on the surface. anyway the way that minerals form is when the lava and minerals already form come together they form new minerals
Why does lava take a long time to cool down?
Lava cools slowly because lava is a poor conductor of heat. Lava flows slow down and thicken as they harden.
What is formed by magma cooling?
Intrusive igneous rock is formed when magma or lava cools quickly.
Why would lava cool more quickly then magma?
Magma is molten rock that is below ground level so it probably wouldn't be exposed to the open air.
Why would lava cool more quickly then lava?
Magma is molten rock that is below ground level so it probably wouldn't be exposed to the open air.
Does andesite cool quickly or slowly?
Lava will cool quickly compared to underground magma.
Do rocks that cool slowly from magma contain more crystals?
No. They would contain fewer, but larger mineral crystals when compared to igneous rocks which have cooled quickly from lava or magma.
Does lava cool slowly or quickly?
Magma that cools quickly forms into igneous rock, when it cools quickly it becomes a lava rock. Lava cools very quickly at first and forms a thin crust that insulates the interior of the lava flow.
Would lava cool quicker than magma?
yes because lava is exposed to the surface while magma is below Earth's suface which would be hotter than the suface
What cools quickly on the earth's surface?
it would be lava , magma is in the ground and flows on earths surface and cools to lava
Are magma and lava sedimentary rocks?
No. Magma and lava are molten rock. When the cool they form igneous rock.
Lava and what can cool to become igneous rocks?
magma
What rocks cool from magma or lava?
magma cools into intrusive igneous rock while lava into extrusive igneous rock
What does Lava on the surface of the earth do quickly?
Lava on the earth's surface will cool quickly.
What rock is formed when magma and lava cool and harden?
Igneous Rock.
