Pacific Rim. DEFINITION of 'Pacific Rim'. The Pacific Rim is a geographic area surrounding the edges of the Pacific Ocean. The Pacific Rim covers the western shores of North America and South America, in addition to Australia, eastern Asia and the islands of the Pacific.
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.
