Why the southern hemisphere is called a watery hemisphere and the northern hemisphere a land hemisphere?
Answers
Most of the land ( about 3/4th of the total landmass ) of the earth is found in the northern hemisphere , hence giving it the name , land hemisphere .
The surface of the Southern Hemisphere is 80.9% water, compared with 60.7% water in the case of the Northern Hemisphere, and it contains 32.7% of Earth's land whereas the Northern Hemisphere contains 67.3% of Earth’s land.
Only two continents are entirely in the Southern Hemisphere. Australia and Antarctica. About 98% of Antarctica is covered by ice, the frozen form of water, that averages 1.9 km (1.2 mi; 6,200 ft) in thickness which extends to all but the northernmost reaches of the Antarctic Peninsula.
The Antarctic ice sheet is the largest single mass of ice on Earth. It covers an area of almost 14 million square km and contains 30 million cubic km of ice. Around 90 percent of the fresh water on the Earth's surface is held in the ice sheet, an amount equivalent to 70 m of water in the world's oceans.
While the mouth of the Amazon River is barely just north of the Equator, about two thirds of its watershed is in the Southern Hemisphere. The Amazon River is the largest river by discharge volume in the world. Some recently modified measurements suggest that this is the longest river in the world whereas previously the Nile River was considered the longest.
Whether or not the Nile is the longest or second longest rivers if the world, one of it sources is also in the Southern Hemisphere. Its main source, the White Nile originates in Rwanda. Its secondary source, the Blue Nile originates in Ethiopia in the Northern Hemisphere. Without all the water coming from the Southern Hemisphere into Egypt, Egyptian civilization would be quite different.
