Azerbaijan is home to a vast variety of landscapes. Over half of Azerbaijan's land mass 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 metres, and others from 0 - 50 meters and up (Gobustan, Absheron). The rest of Azerbaijan's terrain consist of plains and lowlands. Hypsometric marks within the Caucasus region vary from about -28 metres at the Caspian Sea shoreline up to 4466 metres at Mount Bazardüzü.
