Which desert is the hottest desert in the world?
Seven years of satellite temperature data show that the Lut Desert in Iran is the hottest spot on Earth. The Lut Desert was hottest during 5 of the 7 years, and had the highest temperature overall: 70.7°C (159.3°F) in 2005.
Is Sahara Desert the hottest region in the world?

Do People Live In The Sahara? The population of the Sahara is just two million. People who live in the Sahara are predominantly nomads, who move from place to place depending on the seasons. Whilst others live in permanent communities near water sources.
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?
Roughly 80% of deserts aren’t covered with sand, but rather show the bare earth below—the bedrock and cracking clay of a dried-out ecosystem. Without any soil to cover it, nor vegetation to hold that soil in place, the desert stone is completely uncovered and exposed to the elements.
What’s under the sand at the beach?
Often, underneath the loose sand of a beach is a layer of hard, compacted sand, which could be on its way to becoming sandstone if the necessary cement, pressure and heat ever appear — and if is not eroded by severe storms.
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.
