Pebbles that become part of clastic rocks in places like Arizona's Lower Antelope Canyon don't move with the wind but against it, a geosciences professor said. Rather than being pushed into formations, the pebbles, or clasts, have the loose sand around them removed by the wind, Andrew Leier of the University of Calgary said in the journal Geology. The sand removal causes scour-pits to form on the wind side of larger clasts, and the pebbles eventually fall toward the wind into the scours, he...

At first, figuring out how pebble-sized rocks organize themselves in evenly-spaced patterns in sand seemed simple and even intuitive. But once Andrew Leier, an assistant geoscience professor at the U of C, started observing, he discovered that the most commonly held notions did not apply.

Typically we think of rainfall as cleaning the air by removing dust as it falls through the atmosphere and helping plants grow that protect and hold the soil. But a new NASA-funded study looking at some of the world's dustiest areas shows that heavy downpours can eventually lead to more dust being released into the atmosphere.
