Question: Which country has nearly 90% of its territory covered by desert?

Libya is the country where approximately 90% of its landmass is covered by desert, primarily the Sahara Desert. This vast arid landscape significantly influences Libya’s climate, population distribution, and economic activities. Most of its habitable areas are concentrated along the Mediterranean coastline, contrasting sharply with the expansive desert interior.
