Answer: Black Sea and Sea of Azov
Notes: A Russian oil tanker recently split during a storm, spilling oil into the Kerch Strait. The Kerch Strait connects the Black Sea with the Sea of Azov and separates Crimea from Russia's Taman Peninsula. It’s 3 km long, 15 km wide, and 18 meters deep, with its narrowest point being just 3-5 km. Kerch city is located on the Crimean side, and the strait is a vital global shipping route. After Russia's annexation of Crimea in 2014, it has been a point of conflict. The Kerch Strait Bridge, completed in 2018, links Russia to Crimea and is Europe's longest bridge.
