World Geographical Records

The Dead Sea has a salinity of about 34%, making it nearly 10 times saltier than ocean water and the saltiest sea in the world. Its high salt content comes from being in an endorheic basin with high evaporation and minimal outflow. The Red Sea, Black Sea, and Ural Sea are much less salty.

New Guinea is the second largest island in the world after Greenland, covering approximately 785,753 square kilometers. It is located in the southwest Pacific Ocean, north of Australia. Greenland is the largest island, while Borneo and Madagascar rank third and fourth respectively in terms of island size.

Lake Superior is the largest freshwater lake in the world by surface area (82,100 square kilometers) and is located on the border between the United States and Canada. It contains about 10% of all the world's fresh surface water. Chilka Lake and Dal Lake are lagoons in India, and the Caspian Sea is saline, not freshwater.

The Loire River is the longest river in France at approximately 1,012 kilometers (629 miles). It flows through central France and is known for its valley's vineyards and châteaux.

The Sea of Tranquility (Mare Tranquillitatis) is a lunar mare located on the Moon's surface, not in any ocean on Earth. It was the landing site of Apollo 11, the first manned Moon mission.

Sharks primarily live in the deep ocean (open ocean and deeper waters), though some species inhabit coastal areas or coral reefs. Option B is the most accurate among the choices. Sharks don't live on the surface, with mermaids (mythical), or specifically where people are.

Salto Angel Falls (also known as Angel Falls) in Venezuela is indeed the highest waterfall in the world, with a total height of 979 meters (3,212 feet). The statement is factually correct.

The Sea of Tranquility (Mare Tranquillitatis) is a lunar mare on the Moon's surface. It gained fame as the landing site of Apollo 11, where Neil Armstrong and Buzz Aldrin became the first humans to walk on the Moon in 1969.

The Red Sea is the world's warmest sea due to its high evaporation rate, minimal freshwater inflow, and location in a hot arid region. Water temperatures can exceed 30°C (86°F) in summer. The Dead Sea is a lake, not a sea.

The Caspian Sea is the only inland body of water in the list, as it is an enclosed lake with no natural outlet to the ocean. The Caribbean Sea, Mediterranean Sea, and Bering Sea are all connected to the world's oceans.

The Great Barrier Reef off the coast of Queensland, Australia is the world's largest coral reef system. It spans over 2,600 kilometers and consists of over 2,900 individual reefs and 900 islands. The Belize Barrier Reef, New Caledonia Barrier Reef, and Bahamas Barrier Reef are significant but much smaller in comparison.

Lake Baikal in Russia is the world's second most voluminous lake after the Caspian Sea. It's also the world's deepest lake and contains about 20% of all unfrozen fresh water on Earth. Lake Superior is the largest by surface area, while Lake Victoria and Lake Tanganyika are among Africa's Great Lakes but have less volume than Baikal.

Greenland is the world's largest island, covering approximately 836,330 square miles. It's an autonomous territory of Denmark located between the Arctic and Atlantic Oceans, mostly covered by an ice sheet.

The Sahara Desert is the largest hot desert in the world, covering approximately 3.6 million square miles across North Africa. While Antarctica is technically a larger desert (cold desert), Sahara is the biggest hot desert.
