4.2K views · 56 reactions | Pumice is a type of volcanic rock that is light and porous, formed during explosive volcanic eruptions. It is created when highly pressurized, superheated rock is violently ejected from a volcano, and rapidly cools and depressurizes. This rapid cooling traps gas bubbles within the rock, giving pumice its characteristic porous and frothy texture. Due to its low density, pumice can often float on water. #rock #science #earth #geology | vt.physics | Facebook

Pumice is made near the top of a volcano, at a vent where gases are being injected into the magma. It's so fragile and light, it will float in water - just like the dozens of pumice deposits you can find in the river valleys near Glacier Peak volcano. But on the east side? The same pumice deposits were violently ejected during an eruption some 13,000 years ago. Find out what we can learn from the evidence of past eruptions at Glacier Peak on the latest episode of Nick on the Rocks, now streaming

THE WONDER OF PUMICE ROCK Not all rocks sink, some float. Pumice is a volcanic rock formed when hot lava full of gas cools quickly and hardens. The fast cooling traps many tiny air pockets inside, making the rock lighter than water. That is why it floats for months or even years before sinking. Pumice is more than a fun science fact, it has many uses too. It is used for skin care, water filtering, and in lightweight building materials. This floating rock shows the power and creativity of nature.
