Secrete of Yellow Sea

Yellow sea which is shared by China, South Korea and North Korea. As the name suggests, it is really yellow in colour. The reason behind this yellow colour is Huang-Ho river, also known as yellow river. There is Tarim Basin, a desert part of west China.When wind flows toward east towards pacific ocean, it picks up certain sand particle, which they land near the Huang-Ho river Basin. The colour of sand is yellow. The river than drains it self into yellow sea, ultimately colouring the yellow sea.

There is another river by the name "Yalu Jiang", which makes a natural boundary between China and North Korea.
