Pumice ~ Learning Geology

The pumice is made from the gas escapes of the volcanic eruption. This makes abundant vesicles of the pumice to float on water surface. The pumice have thin walls which makes it light weight and the specific gravity of pumice is less than one that gives it the ability to float on water surface.

ALEX STREKEISEN-Basaltic Scoria-

Scoria is relatively low in mass as a result of its numerous macroscopic ellipsoidal vesicles, but in contrast to pumice, all scoria has a specific gravity greater than 1, and sinks in water. The holes or vesicles form when gases that were dissolved in the magma come out of solution as it erupts, creating bubbles in the molten rock, some of ...

Density & Specific Gravity - Meteorite Information

Specific Gravity. In order to measure density, it is necessary to measure the volume of a rock. That's hard to do accurately. Just as useful as density, however, is the specific gravity.Specific gravity is the ratio of the mass (weight) of a rock to the mass of the same volume of water.

Cinder - Wikipedia

A cinder is a pyroclastic material. Cinders are extrusive igneous rocks.Cinders are similar to pumice, which has so many cavities that its low density of 0.641g/cm^3 allows it to float in water.Cinder is typically brown, black, or red depending on its chemical content. A more modern name for cinder is scoria.. Characteristics. The following geologic characteristics define a cinder:
