The Labrador Current is a cold oceanic current that flows south from the Arctic Ocean along the coast of Labrador and Newfoundland in eastern Canada. It meets the warm Gulf Stream near the Grand Banks, creating fog and rich fishing grounds. The Kuroshio and Gulf Stream are warm currents, while the Falklands Current flows near South America.

Lake Superior is the largest freshwater lake in the world by surface area (approximately 82,100 sq km). The Caspian Sea is larger by surface area (371,000 sq km) but it is a saltwater lake, not freshwater. Lake Superior contains about 12,100 cubic km of water, making it the third largest by volume among freshwater lakes.

The Arctic Ocean is the smallest and shallowest of the world's five major oceans, covering approximately 14 million square kilometers. The Pacific is the largest, followed by Atlantic, Indian, and Southern Oceans.

The Caspian Sea is the world's largest inland body of water by area, covering approximately 371,000 square kilometers. It is bordered by five countries and has characteristics of both a sea and a lake.

Majuli, located in the Brahmaputra River in Assam, was officially recognized by Guinness World Records in September 2016 as the world's largest river island. It faces threat from erosion and flooding. Bhola Island (Bangladesh) and other options are river islands but smaller than Majuli.

The Caspian Sea, covering about 371,000 square kilometers, is the world's largest lake by surface area. Despite its name, it's an enclosed body of water without an outlet to the ocean, making it geographically a lake.

Antarctica is the fifth-largest continent and is almost entirely covered by ice, with about 98% of its surface frozen. It is the coldest, driest, and windiest continent.
