which international border does the gariep-orange follow before it enters the sea
Orange River The Orange River (Afrikaans/Dutch: Oranjerivier) is the longest river in South Africa and the Orange River Basin extends extensively into Namibia and Botswana to the north. It rises in the Drakensberg mountains in Lesotho, flowing westwards through South Africa to the Atlantic Ocean. The river forms part of the international borders between South Africa and Namibia and between South Africa and Lesotho, as well as several provincial borders within South Africa. Except for Upington, it does not pass through any major cities. The Orange River plays an important role in the South African economy by providing water for irrigation, as well as hydroelectric power. The river was named by Robert Jacob Gordon after the Dutch Royal House. Other names include Gariep River (used by the Khoi people[4]), Groote River or Senqu River (used in Lesotho). The official name, however, is the Orange River.[5]
Bering Strait The Bering Strait (Russian: Берингов пролив[2], Beringov proliv, Yupik: Imakpik[3][4]) is a strait of the Pacific, which borders with the Arctic to north. It is located between Russia and the United States. Named after Vitus Bering, a Danish-born explorer in the service of the Russian Empire, it lies slightly south of the Arctic Circle being at about 65° 40' N latitude. The present Russia-US east-west boundary is at 168° 58' 37" W.
