Azerbaijan is home to a vast variety of landscapes. Over half of Azerbaijan's landmass consists of mountain ridges, crests, highlands, and plateaus which rise up to hypsometric levels of 400–1000 meters (including the Middle and Lower lowlands), in some places (Talis, Jeyranchol-Ajinohur and Langabiz-Alat foreranges) up to 100–120 meters, and others from 0–50 meters and up (Qobustan, Absheron). The rest of Azerbaijan's terrain consists of plains and lowlands. Hypsometric marks within the Caucasus region vary from about −28 meters at the Caspian Sea shoreline up to 4,466 meters (Bazardüzü peak).
