Definition

Meaning

A large, low-lying, arid desert basin in north-western Egypt, notable as one of the deepest points on the African continent and for its extreme aridity.

In geographical and geopolitical contexts, it can refer to a significant natural barrier that has influenced historical military strategy (e.g., WWII) and a region of potential interest for large-scale engineering or energy projects due to its topography.

Common Mistakes

  • Misspelling: 'Qatar Depression' (confusing with the country Qatar).
  • Incorrect capitalisation: 'qattara depression'.
  • Using 'depression' in the psychological sense.
