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.
Lava can cool rapidly in water, forming structures called pillow lavas. The rate of cooling can be influenced by the temperature of the water and the size of the lava flow, but generally, lava can cool in minutes to hours when in contact with water.
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.
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.
In terms of temperature, lava is much hotter than water and can cause more damage upon contact. However, water has the ability to cool and solidify lava, creating solid rock formations over time. So, while lava is more destructive initially, water has the long-term ability to shape and alter it.
No. Shield volcanoes form from basaltic lava with a low silica content and a low water content.
Yes. Lava will cool in water, though it might not be instantaneous.

On contact with water lava will cool rapidly to form rock.
to try to cool the lava and keep it from advancing.
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.

Lava flows from the rifts and is cooled quickly by sea water
Yes, the heat of the lava may well turn some of the water into steam, but the sea will cool & solidify the lava.
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.
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.
It can cool lava somewhat, but so does air or anything else that is at a lower temperature than the lava. It would not cool lava enough to make noticeable difference.
