All three rock types could be formed in areas under the seas. Two types of rock are most likely to form on the seafloor, however. Sedimentary rock is formed on the seafloor where accumulations of sediments undergo lithification processes. Extrusive igneous rock can form on the seafloor when lava erupts on its surface.

I think it's igneous rocks, because they can be known as 'fire rocks'.

Extrusive igneous rocks


What is the process on how magma flows inside and outside a volcano?

First, the magma breaks open rocks underneath the volcano. Then, it flows up through cracks of the volcano. After it is all the way to the top, the volcano erupts. Then the magma and lava flows outside the volcano.


Why does rocks from fall from the sky?

When a volcano erupts it releases liquid magma into the air and as it falls to the earth it cools down and becomes solid.

What is the throat of a volcano and what does it do?

A volcanic neck is the throat of a volcano and consists of a pipe like conduit filled with hypabyssal rocks. the volcanic Lave from the Magma Chamber comes out through the throat when the volcano erupts. :) hope this helped :)


Why do rocks form?

Igneous rocks form because, magma cools under the ground, or magma erupts, then cools on the ground forming these rocks.

Where does the magma get trapped in the layers of the volcano where the magma never reaches outside?

The magma gets trapped in the layers of the volcano in a magma chamber. This chamber is typically located deep within the Earth's crust, below the volcano's vent. The thick and solidified rocks surrounding the chamber help contain the magma and prevent it from reaching the surface.


What causes volcano to erupt?

Usually the magma clogs causing major pressure causing the volcano to explode violently or some times movement in the earths crust


What is the scientific reason for mount vesuvius' explosion?

The scientific reason for Mt. Vesuvius's eruption, is that pressure on the rocks the closest to the mantle increases when two continental plates collide and push against each other causing the ground to quake, and the rocks to melt and form magma. Then as the magma in the mantle increases the magma rises into the magma chambers. Then the pressure in the magma chambers increases, and it continues to build up until the volcano can't stand the pressure and the volcano erupts, and explodes.
