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.
Farther north, the Atlantic opens into the Arctic Ocean, which is connected to the Pacific by the Bering Strait, forming a continuous expanse of water. 1  The Pacific Ocean, the largest of the oceans, also reaches northward from the Southern Ocean to the Arctic Ocean. It spans the gap between Australia and Asia, and the Americas.
