Want this question answered?
lava, ash and gases come from the centre of the earth where they have been kept for a very long time and they become so cramped that they have to find a way out so they form volcanos.
When lava erupts, it cools and hardens. After long periods of this happening and cooling in layers on top of all the other cooled lava, a mountain of hardened lava rises out of the water and to the surface. This rising mountain soon will become a volcanic island.
i was going to ask this myself. it's a weird one. lava is a fluid and most fluids do evaporate. on the other hand when lava cools it becomes glass or rock which are obviously solids and dont evaporate. so maybe if you kept the lava molten long enough and it gasified enough it would eventually dissappear. who knows
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.
lava
it will not keep going because you have to keep adding salt instead of sugar it will go on fovever if you keep adding salt.
The effect would keep going the more salt you put in it and here r some web sites sciencebob.com

it cant sustain lava
When volcanos erupt they spew ash and moltant lava all over the place. They can cause lots of problems with crop damage.
it takes approxomately about a couple of weeks to clear the lava
Depends on where the lava is how much lava there is etc, Aka if you stick ur head into a pool of lava death is almost instant, But if you stand in a pool of lava it might take around 20 seconds for it to melt your bones and flesh.
It is not recommended to keep the lava lamp on for longer than 10 hours at a time.
It is suggested not to leave it on over night, but it can be kept on for as long as you want.

time!
i think its only 10 hours at a time. but this lava lamp is effectively using for a long time... thats all i know. thank you
