What type of rock is in the attached image? How do you know?iconflash.jpg

Answer 1

The rock in the attached image appears to be igneous rock, specifically a type of volcanic rock known as pumice. This can be deduced from the rock's porous and lightweight appearance, as well as its pale color. Pumice is formed from lava that is highly frothy with gas bubbles trapped in it, which gives it its distinct texture.
