Pumice is formed from magma coming out of volcanoes where rhyolite would have formed, (Destructive plate margin), but has cooled so fast that it appears glassy, and almost non-crystalline.

Pumice is found after volcanic eruptions producing lava.
it is found worldwide
Pumice is formed from volcanic eruptions and can be found in countries with active or dormant volcanoes, such as Italy, Greece, New Zealand, and the United States. The largest producer of pumice is typically considered to be Italy.
The world's rarest fern is likely to be the small, unassuming plant known as the Huperzia polydactyla. This fern is considered critically endangered and is only found in a few locations in New Zealand.

Pumice can be found after volcanic eruptions, as it is formed when lava with high water and gas content is rapidly cooled and solidified. The resulting porous rock floats on water due to its low density and is often found washed up on beaches or shores.
Large amounts of pumice are found in Italy, Turkey, Greece, Spain, Canada, and parts of the United States, especially the Rocky Mountain and Pacific Coast states. In many of these locations, pumice is mined to be sold for a variety of uses.
Yes, pumice can be found in the US, mainly in western states with active volcanic activity such as Oregon, California, and Nevada. Pumice is a lightweight volcanic rock formed from frothy lava with trapped gas bubbles.
it depends what part of the world you come from. because pumice is a type of rock produced by volcanoes if you lived in a part of the world where ther are lots of volcanoes then no it would not be a rare substance but if you lived in a part of the world that ther was no volcanoes then pumice would be rare .Pumice is not rare it is a very common volcanic rock.
The lightest rock in the world is pumice. Pumice is a type of volcanic rock that is formed when lava with high water and gas content is rapidly cooled. It is so light that it can float on water.
Pumice is usually found around the shore of beaches and rivers, due to the lightness in weight.
