Water running down slope forms gullies, while some soaks into clay-rich rocks and soils. Scoria and pumice also differ in colors. The vesicles are trapped when magma cools and solidifies. This low weight allows engineers to use less structural steel in buildings and homes. Depressurization allows for the formation of gas bubbles (usually water and CO2) which become frozen in the rapidly cooling lava. It occurs when minerals with a higher melt point have time to crystallize in the magma before it erupts to the surface and the entire melt rapidly crystallizes around them. The creation of scoria is a fascinating process that always follows a few simple rules but can vary significantly in the details, which is the reason scoria can look so different from one specimen to another.
