Some types of pumice have enough air inside to float.
Pumice is a lightweight volcanic rock that floats on water due to its high porosity.
Pumice is a grey volcanic rock so full of gas bubbles that it is able to float on water.
Metamorphic rock, such as schist or gneiss, can be formed when volcanic rock is altered by heat and pressure. This process can cause the mineral composition and texture of the rock to change, resulting in a new type of rock with different features than the original volcanic rock.
Pumice is a light, porous volcanic rock that is commonly used in beauty and skincare products for exfoliation. It forms when volcanic lava rapidly cools and traps gases, creating its characteristic porous texture.
The type of rock typical of island arcs is andesite. Andesite is an intermediate volcanic rock that is commonly found in volcanic arcs where oceanic crust subducts beneath continental crust, forming magma that eventually erupts to create volcanic islands.
Pumice is a lightweight volcanic rock that floats on water due to its high porosity.
Floating rocks: pumice. Non-floating rocks: all but pumice. Pumice can float on water because its density is so low, due to trapped bubbles of air which formed during its solidification from lava.
The on rock that floats is a pumice. It is a kind of volcanic glass. The reason it floats is because it has big pours all over it. I'm only in 8th grade and I still know the answer.
Pumice is a type of rock that can float on water due to its high porosity and low density. It is formed from volcanic eruptions and is commonly found near volcanic regions.
Very porous rocks such as pumice can be very light and have the potential to float on water. Pumice is a volcanic rock.
Pumice is a grey volcanic rock so full of gas bubbles that it is able to float on water.
volcanic rock from cape verde
volcanic rock , or even a type of rock in a classified section , sedimentary , metaphoric , or even igneous. the answer is volcanic rock a type of metaphoric rock. :)
Volcanic.
Volcanic rock is extrusive igneous rock.
volcanic rock
a lava rock i think
