Lava on Earth's surface is exposed to air, which is of course much cooler than the lava. The air then carries heat away from the surface of the lava flow rather quickly. Since rock, molten or otherwise, is a poor conductor of heat the interior of the lava flow cools much more slowly and does not supply heat to the cooling outer layer. As a result the lava forms a thing solid crust. Until a thick insulating crust has built up the surface will remain quite hot, just not hot enough to be molten.
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.
lava shoots out of the top
A 'blob' of lava, or magma, can either flow into the sea and eventually cool to form rock or be fired out of the volcano and cool faster when it hits the sea. The flowing lava has a high level of silica; making it runny and the explosion lava (which will cool to form rocks like granite) are high in iron.
When lava cools at the top of a volcano, it forms igneous rocks such as basalt or andesite. These rocks can sometimes create formations like lava domes or hardened lava flows.
No. Magma and lava are molten rock. When the cool they form igneous rock.
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.
how do you cool the lava bucket in into the inferno
Yes. Lava will cool in water, though it might not be instantaneous.
this is like warm, less dense air rises while cool more dense sinks. This is like the lava lamp the hot "lava" floats up to the top and and the cooler "lava" sinks down to the bottom and heats up and rises and the cooling stuff at the top is now sinking
No. Lava heats up the air. In turn, the air cools the lava.
Lava on the earth's surface will cool quickly.
micock its a really cool place it has a volcano at the top that shoots out lava when u please it

lava lamps are used to have something cool in your house
when lava emerges on out of mountain then the molten lava cool to form rocks.
Lava at the top of a volcano will generally flow downhill.
A lava lamp is a pretty interesting thing, when it is cool, it looks like it's made of candle wax, because it is. Wax is strange, because when it is hot, it rises, but when it is cool, it sinks, so the bulb at the bottom heats the wax, and it floats to the top, but at the top, when it starts to cool down, it sinks. cool huh?
