How deep is the sand in the Sahara Desert, and what's underneath it.?

Answer 1

The sand is just over 3 feet deep, and under it is a vast freshwater lake.
If only the poor fools who die needlessly there every year KNEW this simple fact, think of the countless lives it might have saved over the years.
Why it is not widely known, is a mystery to me. I suspect a conspiracy theory.

Answer 2

Variable, from nothing to more than 200 feet.
Satelite photos suggest an ancient dried up river system but this hasn't been confirmed.
Figure above obtained from Shat Melrir where they drill for a water bearing layer of sand 200 feet below the surface.

Answer 3

No. not without being waiting to regulate the aspects. like each and every deserts, the Sahara replaced into formed simply by a loss of water from rain. like each and every deserts, it could desire to be irrigated to coach it into effective farmland. yet turning on the rain is something that we are nonetheless a lengthy way from dealing with. And if we rigidity rain onto 2 million sq. miles of desolate tract, we would be vastly changing the aspects someplace else, with a bit of luck the middle of the Indian or Pacific oceans. Terraforming refers back to the changing of a finished planet, not basically a small section, to coach it right into a clean Earth (Terra). Mars could be Terraformable simply by fact it somewhat is almost heat sufficient, has a lot of water, and sufficient environment to get the technique going. Venus might in all probability require thoroughly diverse procedures and thank you to it somewhat is closeness to the solar, could be previous our applications for yet another 500-1000 years. How lengthy it would take to terraform any planet might matter on a sequence of aspects unique to each and each planet. the biggest in each and every case, no remember if forcing rain onto the Sahara or turning Venus into Las Vegas or Miami, is going to be money, dedication, and environmentalists that prefer Mars and Venus to stay purely as they are, ineffective.

Answer 4

The Sahara is the world's largest hot desert, and second largest desert after Antarctica. At over 9,000,000 km² (3,500,000 sq mi), it is almost as large as the United States, and is larger than the 48 contiguous states. The Sahara is located in North Africa and may be as much as 2.5 million years old. The name is an English rendition of as-ṣaḥrā, the Arabic word for "desert.

Answer 5

Its a interesting question.
Answer cannot be guessed.
If you can access some bore hole log or seismic data or electro sounding data, you may find the answer. I am sure some wide spaced deep bore hole (for ground water) log might be availabale and the data could be accessed at some geological agencies working in the area.
Try your luck.
