Why does a volcano explode under water?

Answer 1

When a volcano erupts underwater, the lava comes in direct contact with water. If the water isn't too deep, then the heat will cause it to flash boil. The sudden formation of steam then causes and explosion.

Answer 2

Yes, volcanoes can erupt underwater. They can erupt wherever they are.
Yes. Most of the volcanic activity on Earth is actually underwater and goes largely unnoticed. Underwater volcanoes will sometimes grow above the surface to form new islands.

Answer 3

Most underwater volcanoes are found at mid ocean ridges. Here, material wells up in the mantle as plates pull apart. As the crust thins at these locations material in the mantle melts and rises up to form volcanoes.

Answer 4

When magma rises to the surface underwater, the pressure from the water column above can prevent gases from escaping, causing a build-up of pressure until it explodes. The rapid cooling of the magma in water can also create explosive reactions, leading to underwater volcanic explosions.

Answer 5

I believe so, it's very interesting, isn't it?

Answer 6

because that's where they come from oceanic plates collide one goes under the other it melts rises to the seabed and breaks out forming a volcano kinda like a spot

Answer 7

Yes, most volcanoes are located under water at the mid-ocean ridges. They can be one of the reasons that tsunamis happen.

Answer 8

Yes. Many volcanoes have formed on the seafloor and eventually built up into islands.

Answer 9

They are developed the same way they're developed out of water.
