Yellow Sea is an arm of the Pacific Ocean that extends inland for about 400 miles (640 kilometers) between the east coast of China and Korea. The Chinese named this area the Huang Hai (Yellow Sea) because the waters along the banks are a yellow, muddy color. The Huang River carries deposits of yellow earth (huangtu) to the Yellow Sea. The sea is about 300 feet (91 meters) deep in its deepest part. It covers 480,000 square miles (1,243,194 square kilometers). Qingdao lies on China’s coast on the southern shore of the Shandong Peninsula. Lushun and Dalian are at the southern end of China’s Liaodong Peninsula. The Korea Strait connects the Yellow Sea with the Sea of Japan (also called the East Sea). At the north, the Yellow Sea forms Laizhou Bay, the Bo Gulf, the Liaodong Gulf, and Korea Bay.
