THE LATEST IN THE GEOSCIENCES

Crater Filled with Lava Collapses

High Plains Haboob Blows Across Five States

Betcha can’t guess why this caught my eye. Ok, maybe you can.

A Haboob is a type of dust storm commonly seen in arid areas. The word itself is Arabic.

Specifically, a haboob is a dust storm that happens where there is a density difference in air that flows across the land. It’s a density current that carries with it a bunch of dust.
