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.
Located between the Southern Ocean, Asia, Australia and the Americas, the Pacific Ocean occupies about one-third of the Earth's surface. Containing almost twice as much as the world's second largest body of water, the Atlantic Ocean, the Pacific Ocean holds more than half of the Earth's open water supply. In fact, the Pacific Ocean's basin, or the land below sea level, is so large that it could hold all of the world's continents. Besides being the biggest, the Pacific is also the oldest of the existing ocean basins.
