Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean

Sierra Madre Occidental
The Sierra Madre Occidental is a major mountain range system of the North American Cordillera, that runs northwest–southeast through northwestern and western Mexico, and along the Gulf of California. The Sierra Madre is part of the American Cordillera, a chain of mountain ranges (cordillera) that consists of an almost continuous sequence of mountain ranges that form the western 'sounds' of North America, Central America, South America and West Antarctica. Etymology The Spanish name ''sierra madre'' means "mother mountain range" in English, and ''occidental'' means "western", these thus being the "Western mother mountain range". To the east, from the Spanish ''oriental'' meaning "eastern" in English, the Sierra Madre Oriental range or "Eastern Mother Mountains" runs generally parallel to the Sierra Madre Occidental along eastern Mexico and the Gulf of Mexico. The range extends from northern Sonora, a state near the Mexico–U.S. border at Arizona, southeastwards to the Trans ...
