Azerbaijan is home to a vast variety of landscapes. Over half of Azerbaijan's landmass consists of mountain ridges, crests, yailas, 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).
