In undersea eruptions, almost instantly. On land it depends on the viscosity and other factors. On land, could be minutes, hours, days, weeks.
Lava cools slowly because lava is a poor conductor of heat. Lava flows slow down and thicken as they harden.
Yes. Lava cools and hardens into rock.
Actually, it does not. It is soft.
Lava hardens into extrusive igneous rock.
Lava and magma are not rocks because they are liquids and cant harden because they are to hot to harden and cant cool themselves down long enough to form a hard structure. Magma and lava is rock - it's just been superheated by the Earth's core.
It takes at least 3 days to harden.
It hardens into volcanic rock. The kind of rock depends on the kind of lava.
Both pillow lava and pahoehoe lava have about the same composition and harden into a kind of rock called basalt.
It is called Lava
About a hour mabye a day
it is kaka shamucky
it turs to rock
Igneous rocks form from the hardening of magma and lava.
It harden really quickly or instantly, and is called a pillow lava. :D
volcanoes will erupt and let out lava then the lava will harden and that will be new land.
At least a month to dry and another week to harden
12 seconds...
lava helps harden with stone and minerals grow it
Because it cools down and changes its state of mater.
NOTHING IT JUST DOES BECAUSE OF THE HEATNESS AND THE COLDNESS
Igneous Rock.
It hardens and turns it to rock.
If there is no fresh supply of lava coming in, it may take a matter of hours to days. Small globs of lava will cool faster.
About four hours and twenty minutes.
It becomes igneous rocks>
