It is partly covered by sea Ice throughout the year and almost completely in winter. The arctic ocean's surface temperature and salinity vary seasonally as the ice over melts and freezes; its salinity is the lowest on average of the five major oceans due to low evaporation, heavy fresh water inflow from rivers and streams, and limited connection and outflow to surrounding oceanic water with higher salinities. The summer shrinking of the ice has been quoted at 50%. The US national snow and ice Data center uses satellite Data to provide a daily record of arctic sea ice cover and the rate of melting compared to an average period and specific past years.

The average depth of Southern Ocean is about 23,737 ft but its deepest greatest depth is around 7,236 meter which is at South Sandwich Trench. The southern ocean geologically the youngest of the oceans was formed when Antarctica and and south America moved apart, opening the drake passage, roughly 30 million years ago. The separation of the continents allowed the formation of the Antarctic Circumpolar current. With a northern limit at 60 degree S the Southern Ocean differs from the other ocean in that its largest boundary, the northern boundary does not abut a landmass.

The first team to navigate the Yenisei's entire length, including its violent upper tributary in Mongolia was an Australian, Canadian effort completed in September 2001. Ben Kozel, Tim Cope, Colin Angus and Remy Quinter were on this team. Both Kozel and Angus wrote books detailing this expedition, and a documentary was produced for National Geographic Television. Studies have shown that the Yenisei suffers from contamination caused by radioactive discharges from a factory that produced bomb-grade plutonium in the secret city of Krasnoyarsk-26, now known as Zheleznogorsk. 

4. Mississippi ( North America )

  The Mississippi river is the chief river of the second drainage system on the north American continent, second only to the Hudson bay drainage system. Flowing entirely in the United Sates It rises in northern Minnesota and Meanders slowly Southwards for 2,320 miles to the Mississippi river Delta at the gulf of Mexico. With its many tributaries, the Mississippi's watershed drains all or parts of 31 U.S. states and two Canadian provinces between the Rocky and Appalachian mountains. The Mississippi ranks as the fourth longest and fifteenth largest river in the world by discharge. The river either borders or passes through the states of Minnesota Wisconsin, Lowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi and Louisiana. Since modern development of the basin began, the Mississippi has also seen its share of pollution and environmental problems- most notably large volumes of agricultural runoff, which has led to the gulf of Mexico dead Zone off the Delta. In recent years, the river has shown a steady shift towards the Atchafalaya river channel in the Delta; a course change would be an economic disaster for the port city of new Orleans. 

3. Yangtze ( China )

  The Yangtze which is 6380 km long, is the longest river in Asia and the third longest in the world. The river is the longest in the world to flow entirely within one country. It drains one fifth of the land area of the people's republic of China and its river basin is home to one third of the country's population. The Yangtze is the sixth largest river by the discharge volume in the world. In recent years the river has suffered from industrial pollution, agricultural run-off, siltation and loss of wetland and lakes which exacerbates seasonal flooding. Some sections of the river are now protected as nature reserves. A stretch of the Yangtze upstream flowing through deep gorges in western Yunnan in part of the three parallel rivers of Yunnan protected areas. a UNESCO world heritage site. In mid 2014, Chinese government announced it was building a multi tier transport network comprising railways, roads and airports to create a new economic belt alongside the river.In terms of discharge it occupies position six and it flows 3,915 miles. Its origin is Qinghai-Tibet Plateau and drains at east China at Shanghai. 

2. Amazon ( South America )

 The Amazon river, usually abbreviated to Amazon in South America is the largest river by discharge volumes of water in the world and according to some authors, the longest in length. At an average discharge of about 209,000 cubic meters per second approximately 6,591 cubic kilometers per annum, greater than the next seven largest independent rivers combined the Amazon's represents 20% of the global riverine discharge to the ocean. The Amazon basin is the largest drainage basin in the world, with an area of approximately 7,050,000 square kilometers. The portion of the river's discharge basin in the Brazil alone is larger than any other river's basin. The Amazon enters Brazil with only one fifth of the flow it finally discharges into the Atlantic ocean, yet already has a greater flow at this point than the discharge of any other river. There has a contrasts between the Nile and the Amazon river regarding which one of them is the longest. Some Geographers state the Nile is the longest where the others refer Amazon is the longest. Advance satellite imagery technology was ranting researchers to agree the rivers dimensions even more exactly. 

1. Nile ( North East Africa )

 Standing on the first position is the world's largest and longest river is Nile river. The Nile is a major North flowing river in Northeastern Africa. It is commonly regarded as the longest river in the world, through other conflicting cite a 2007 study that gave the title to the Amazon river in South America. The Nile which is 6,853 kilometer long, is an International river as its drainage basin covers eleven countries. The Nile has two major tributaries, The white Nile and Blue Nile. The white Nile is considered to be the headwaters and primary stream of the Nile itself. The Blue Nile, however, is the source of most of the water and silt. The white Nile is longer and rises in the great lakes region of central Africa, with the most distant source still undetermined and located in either Rwanda and Burundi. It flows north through Tanzania, lake Victoria, Uganda and south Sudan. The Nile river is documented to be the longest river on the planet which takes a journey of 4,132 miles before it drains into the Mediterranean sea. Some of the major developments that have been as a result of the river are towns such as Cairo, Khartoum, Aswan and Luxor. The Nile has been the lifetime of civilization of Egypt since the stone age with most of the population and all of the cities of Egypt resting along those parts of the Nile Valley lying north of Aswan.
