5.2: Igneous Rock Identification

Igneous Rocks. Igneous rocks (fiery rocks) are made when molten material inside or outside the earth cools and becomes solid. This melted rock is called magma when it is inside the earth. When magma finds its way to the surface through cracks or volcanoes, it is called lava.When lava cools on top of the earth's surface, it forms extrusive, or volcanic, …

Pumice: A Frothy, Light-Colored Volcanic Rock with Many Uses

Pumice is a very low-density, form-like, mostly light-colored glassy volcanic rock with a vesicular texture, not a mineral. This rough, porous rock forms from mostly silicic, high-viscosity, volatile-rich lava during an explosive volcanic eruption. The explosive eruption ejects blobs of lava, which rapidly froth up, cools, and solidifies ...

How Is Pumice Formed? | Sciencing

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. The cooling of the rock below the rock's melting point means that when the …

Pumice | Minerals Crushing in Mining

Pumice is a type of extrusive volcanic rock, produced when lava with a very high content of water and gases is discharged from a volcano. As the gas bubbles escape, the lava becomes frothy. When this lava cools and hardens, the result is a very light rock material filled with tiny bubbles of gas. Type: Rock. Color: White or light white.

Pumice | OpenLearn

Pumice is formed when volcanoes erupt explosively. It comes from the same kind of magma which would form granite or rhyolite, that is, a magma that contains lots of silica (quartz). Magma with lots of silica is usually thick and sticky. Some of the gases which cause the explosive eruption get trapped in the magma and form gas bubbles.
