INSUFFICIENT LEANING
Recorded sources

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that most of the Sahara desert is bare rock and gravel rather than sand?

Unclear. Two reference items describe the Sahara as containing rocky plateaus and gravel plains alongside sand seas, and one forum answer quotes Wikipedia saying the Sahara is mainly rocky hamada with ergs only a minor part. None of the placed items quantifies the proportion of bare rock and gravel versus sand, so the claim is only partially covered.
