Question

Which is the only type of rock that floats?

Answer 1

The only type of rock that floats is pumice. Pumice is an extrusive igneous rock that is formed when lava with high amounts of gas and water erupts from a volcano. As the lava cools and solidifies, gas bubbles are trapped in the rock, creating a porous and lightweight material that floats on water. Pumice is often used in horticulture and in the production of lightweight concrete and abrasive cleaners.

Answer 2

The only type of rock that floats is pumice, which has a unique and porous structure. It is formed when lava cools quickly, trapping gas within its structure, causing it to float on water. Despite being a rock, pumice is often used for cleaning and exfoliating due to its natural abrasive properties.

Answer 3

The only type of rock that floats is pumice. Pumice is a light, porous rock that forms when molten lava cools quickly. It is full of air pockets, which give it a low density and allow it to float on water.
