It has molten material that originates from partial melting of the earth's mantle or sometimes earth's crust. Basaltic Lava (the most abundant) is mostly made up of the minerals plagioclase, olivine and pyroxene.

Water would make it cool faster.

How might under water lava differ from surface lava?
Under water lava would be colder than normal lava. So they would differ a lot.
Why doesn't water cool the lava?
Water does cool lava, but not instantly. For one thing, lava is a poor conductor of heat, so when lava erupts underwater the outside cools fairly quickly to form solid crust, but the inside remains molten. Second, the water in contact with the lava or crust (which is still quite hot) boils and forms an insulating layer of steam.
How fast can lava cool under water?
slower than charismaes
How long does the lava stay hot for?
It usually depends on how hot the lava and how cold the water is. I think it can take around half a minute for the lava to cool off when its in cold water and that's all i can think of.
Why does lava form a rock when lava is cool?
Because lava is molten rock, which has melted, so when it cools down it turns back into rock, like water into ice.
Will lava cool off when it drops in water?
Yes. Lava will cool in water, though it might not be instantaneous.
What is the difference between lava and water?
that lava is a hot sup stance and water is a cool substance
What cools down lava?
Lava cools in the ocean waters. It will also cool down as it moves.
What happens to lava when it enters the ocean?
On contact with water lava will cool rapidly to form rock.
Why did the villagers pump water on the lava from Eldfell when it erupted in 1973?
to try to cool the lava and keep it from advancing.

Why does lava cool rapidly along mid ocean ridge?
Lava flows from the rifts and is cooled quickly by sea water
When lava reaches the ocean does it become a rock?
Yes, the heat of the lava may well turn some of the water into steam, but the sea will cool & solidify the lava.
How long does the lava stay hot for?

Does lava cool after a few years?
Exposed lava may cool in a matter of hours to days under some circumstances and may cool in seconds if immersed in water. Molten rock underground, called magma, takes years too cool.
