How deep is the sand in the Sahara?

The depth of sand in ergs varies widely around the world, ranging from only a few centimeters deep in the Selima Sand Sheet of Southern Egypt, to approximately 1 m (3.3 ft) in the Simpson Desert, and 21–43 m (69–141 ft) in the Sahara. This is far shallower than ergs in prehistoric times were.

What is underneath desert sand?

How deep is the sand on beaches?

The shoreline moves back and forth and beaches can stack to thicknesses of many 100’s of meters. I’ve drilled beach sands of over 700m thickness. Excluding stacking, beach sand thicknesses seem to average between 1 and 3 meters.

Where does the sand on a beach go when the beach ends?

Along the way, sand is washed ashore, temporarily resting on beaches, until it is re-suspended in the ocean by wave action or wind. The one-way journey down the coast ends when sand is blown inland forming sand dunes, or more commonly, when it flows into a submarine canyon.

What causes beaches to move?

Sand grains move along the shore and up and down beaches because of currents made by waves. Waves break when they reach shallow water, creating turbulence. This area is called the surf zone. The turbulence kicks up the sand and then currents move it along the beach.
