Is there any way to stop a lava flow why not?

There's no way to stop lava. Once fissures open and the hot stuff starts flowing, it's best not to fight nature. "The flows cannot be stopped, but people have tried in the past," said Benjamin Andrews, director of the Global Volcanism Program at the Smithsonian National Museum of Natural History.

And another question, what does lava taste like?

Originally Answered: If you could taste lava, what would it taste like? It's generally metallic with a smokey nose and lots of heat. Be specific different types of rock can taste different. Mostly once cooled all volcanic rocks have a non taste. What happens when lava hits salt water? As the lava boils away the seawater, more of its surface is exposed to the water, which transfers heat more quickly, the U.S Geological Survey (USGS) Volcano Watch says. Steam is then produced at a more rapid rate.

Is lava dry or wet?

The answer lies in how you define "wet". If we're using it as an adjective (definition: covered or saturated with water or another liquid), then lava is a liquid state so it therefore it's wet. But nothing touched by lava is left damp or moist, which means that you can't really use wet as a verb to describe lava. Subsequently, why is water wet? Water is wet, in the sense of being a liquid which flows easily, because its viscosity is low, which is because its molecules are rather loosely joined together.

Does lava come from Earth's core?

Lava (which as you undoubtedly know, is partially molten rock erupted by volcanoes) typically comes from the mantle-the Earth's middle layer, sandwiched between the crust and the core.
