The Nile River originates chiefly from Lake Victoria, which rests at the border of the African countries of Kenya, Uganda and Tanzania. The lake is the largest on the continent of Africa and the second-largest freshwater lake in the world.
A:The Arctic Ocean is the smallest ocean in the world and is about 8 percent of the size of the Pacific Ocean. Its water is consistently cold with temperatures ranging between minus 30 to minus 70 degrees Celsius throughout the year. When the icy water turns into an ice sheet, it forms a mass that is four times the size of Texas.
A:There are a variety of animals that live near or on the Nile River, including the Nile crocodile, hippopotamus, rhinoceros, monitor lizard, perch, catfish, red-billed ibis and the pied kingfisher. The animal most synonymous with the Nile Rive may be the Nile crocodile.
A:A super typhoon is a storm that sees wind speeds of at least 150 miles per hour for a minimum of one minute, according to the National Oceanic and Atmospheric Administration. Such a storm is the equivalent of a category 5 hurricane in the Atlantic basin or a severe tropical cyclone in the Australian basin. The U.S. Joint Typhoon Warning Center coined the term "super typhoon."
A:At 615,000 square miles, the Gulf of Mexico is the largest gulf in the world. A gulf is defined as a portion of a larger body of saltwater that is partially enclosed by land. In the case of the Gulf of Mexico, the lands that partially enclose it are Mexico's northeastern coast and the region of the U.S. that is known as the Gulf Coast, which includes the Florida panhandle and the coastal areas of Alabama, Mississippi, Louisiana and Texas.
A:The width of the Amazon River varies from only 1 mile in some places during the dry season to as much as 30 miles in the wet season. The mouth of the Amazon where it meets the Atlantic Ocean is more than 250 miles wide.
A:The main difference between a geyser and a hot spring is that a geyser is plugged with an obstruction near the opening of the spout and a hot spring is allowed to flow freely. Both geysers and hot springs get their water from rain and snow that melts and seeps into the ground, which is then heated by magma.
A:There are over 30 rivers in the United States that flow north, and over 60 throughout the entire world. The Nile, which is the longest river on Earth, is arguably the most famous river that flows in a northerly direction.
A:Examples of producers in lakes and ponds include algae, phytoplankton, starwort, spiked water milfoi, great willowherb, water lilies, native grasses and wildflowers. Aquatic plants come in three varieties: those that grow completely underwater, those that float on water and those that root underwater but reach above the water's surface.
A:The Nile is a freshwater river, and it supplies Egypt with the majority of its fresh water. Historically, Nile River civilizations were able to avoid the problem of excessive salt ruining arable land by using the natural flooding of the Nile rather than irrigation to water their crops.
A:The smallest ocean in the world is the Arctic Ocean. Located in the northern polar region, this ocean covers approximately 5.4 million square miles. Countries that border this ocean include Canada, Greenland, Russia, Norway and the United States through Alaska's coastline.
A:Thanks to its extremely high salinity, the Dead Sea makes the human body highly buoyant. With its salt content as high as 35 percent, the sea is 10 times as salty as the average ocean. This high density compared to the average mass of a human being makes for the ideal conditions for floating effortlessly.
A:Ocean waves have different names and they are classified according to their periods. Ripples are small waves caused by the wind blowing across the sea surface, and they have an interval of less than 0.5 seconds.
A:Niagara Falls is situated on the border of the Canadian providence of Ontario and the state of New York. The Falls consist of three waterfalls: the American Falls, the Bridal Veil Falls and Horseshoe Falls.
A:There are five Great Lakes. The names of the Great Lakes are Erie, Huron, Michigan, Ontario and Superior. The lakes border the American states of Illinois, Indiana, Michigan, Minnesota, New York, Ohio, Pennsylvania and Wisconsin, as well as the Canadian provinces of Ontario and Quebec.
A:People use rivers for transportation and as a source of natural resources. For example, people draw water from rivers to fulfill their drinking, bathing, irrigation, cooking and industrial needs. People also harvest fish, shellfish, mollusks, ducks and other food animals from rivers.
A:The four geographical boundaries that divide Europe from Asia are the Bosphorus, the Dardanelles, the Caucasus and the Ural Mountains. Together, these four boundaries create a geographical line that stretches extends north to south through the western quarter of Russia, goes around the western boarder of Kazakhstan and the Caspian Sea, and runs east to west along the northern border of Turkey and Azerbaijan.
A:Cold water currents start near the North and South Poles. Currents originating near the North Pole travel south through the Atlantic Ocean, gradually growing warmer until they reach Antarctica, where they become cold again. Near Antarctica, these currents split, with one going to the Indian Ocean and the other to the Pacific, again becoming warmer. These currents loop back to the Atlantic Ocean and head north toward the Arctic.
