Which process could lead directly to the formation of pumice rock
Pumice rocks are formed due to the air that is trapped in
between the rocks, a body of magma spurting out with dissolved gas under
pressure. As the magma cracks through the Earth’s surface, the sudden pressure drop
causes the gas to come out of the solution. The flash of gas form the vent slices
the magma and blows it out as a molten lather. The lather hastily solidifies as
it flies into the air and falls back to Earth as pieces of pumice.
Answer:
Pumice is formed by lava coming into contact with water. This occurs most often with volcanoes near or under water. When the hot magma comes into contact with the water, rapid cooling and rapid de-pressurization creates bubbles by lowering the boiling point of lava.
