The inch is usually the universal unit of measurement in the United States, and is widely used in the United Kingdom, and Canada, despite the introduction of metric to the latter two in the 1960s and 1970s, respectively.
The Pacific Ocean meets the Atlantic south of South  America at Cape Horn, and over the North Pole (the ice-cap is only  floating sea-ice). In reality, the Pacific and Atlanâ¦tic Oceans only  exist as separate oceans because we agree to draw an imaginary line  that separates and divides them.
The Atlantic Ocean, the second biggest, extends from the Southern Ocean between South America, Africa, North America and Europe, to the Arctic Ocean. The Atlantic meets the Indian Ocean south of Africa at Cape Agulhas. The Indian Ocean extends northward from the Southern Ocean to India, between Africa and Australia.
