Ukraine (Listeni/juːˈkreɪn/; Ukrainian: Україна, transliterated: Ukrayina, [ukrɑˈjinɑ]) is a country in Eastern Europe. It has an area of 603,628 km2 (233,062 sq mi), making it the largest country entirely within Europe. Ukraine borders Russia to the east and northeast, Belarus to the northwest, Poland, Slovakia and Hungary to the west, Romania and Moldova to the southwest, and the Black Sea and Sea of Azov to the south and southeast, respectively.
The Sea of Azov is the shallowest sea in the world, reaching maximum depths of just 14 metres. The warm, nutrient-rich water is full of algae. In the summer, brightly coloured swirls of green algal blooms can be seen from space.
The Black Sea is a sea in Southeastern Europe. It is bounded by Europe, Anatolia and the Caucasus and is ultimately connected to the Atlantic Ocean via the Mediterranean and the Aegean Seas and various straits. The Bosphorus Strait connects it to the Sea of Marmara, and the Strait of the Dardanelles connects that sea to the Aegean Sea region of the Mediterranean. These waters separate eastern Europe and western Asia. The Black Sea is also connected to the Sea of Azov by the Strait of Kerch.
