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.
Do obsidian rocks cool fast?
Yes, obsidian rocks cool very fast. This volcanic glass forms when lava cools rapidly, preventing the growth of mineral crystals and resulting in a smooth, glassy texture.
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.
Igneous rocks under water?
NO of course not. They are from lava.
How might under water lava differ from surface lava?
Underwater lava, known as pillow lava, cools more rapidly than surface lava due to the rapid transfer of heat to the surrounding water. This results in the formation of rounded, pillow-shaped structures. Additionally, underwater lava may be more enriched in certain elements due to interactions with seawater.
Will lava cool off when it drops in water?
Yes. Lava will cool in water, though it might not be instantaneous.
What form when lava cool so quickly that crystals cannot form?
When lava cools extremely fast it forms volcanic glass, better known as obsidian. This often occurs when lava hits water.
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.
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.
What cools down lava?
Lava cools down primarily through heat loss to its surroundings, such as the surrounding air and ground. Water can also cool lava quickly by causing it to solidify rapidly. Other methods include covering the lava with ash or other insulating materials to help it cool more slowly.

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.
Does andesite cool quickly or slowly?
Lava will cool quickly compared to underground magma.
