Romania has diverse landforms including the Black Sea coastline with warm air and water temperatures, the Carpathian Mountains containing the highest peak at 2554 meters, and the Danube River flowing through regions like the Getic Plateau, Western Hills and Plains, Transylvanian Plateau, and Delta. Romania's ecosystems feature the lynx as the national animal, dog rose as the national flower, and a climate with cool spring mornings and hot days giving way to dry, cool autumns and very cold, snowy winters where temperatures range between 0 and -5 degrees Celsius.
