What Algeria's geographic profile is telling you
Algeria's geography is best read as a transition from the wetter Mediterranean north through elevated semi-arid interior zones into the Sahara. That sequence explains the country's sharp climate and relief contrasts without reducing the landscape to a single desert profile.

Sources & methodology
Algeria's profile uses Ministry of Foreign Affairs material for national relief and climate, with an Algerian diplomatic tourism page providing the Mount Tahat reference. The page remains limited to physical geography and avoids unrelated political, historical or cultural material from those source pages.
