What is the Continental Divide?

I'm a truck driver and i passed a sign saying continental divide in New Mexico the other day and i was wondering as to what it was.

1. The continental divide is a line running from north to south which indicates the start of the rocky mountains
2. The reason for the name: The Continental Divide in the Americas is the line that divides the flow of water between the Pacific Ocean and Atlantic Ocean. Rain or snow that drains on the east side of the Continental Divide flows toward the Atlantic Ocean while precipitation on the west side drains and flows toward the Pacific Ocean. (However, some rivers empty into the desert and don't end up in the oceans.) Its also an excellent movie with John Belushi and Blair Brown
3. The Continental Divide is the geographic area in North America where the rivers flow in opposite directions - on the east side of the divide, rivers flow east, on the west side of the divide, rivers flow toward the west. Lewis and Clark first noticed this on their exploration. To quote from Yahoo: "Continental Divide is the "backbone" of a continent. In North America, from N Alaska to New Mexico, it moves along the crest of the Rocky Mts., which separates westward-flowing streams from eastward-flowing waters. In SW New Mexico the divide crosses an area of low relief; it becomes more distinct in N Mexico, where it follows the Sierra Madre Occidental. In the United States it has been called the Great Divide, a name also occasionally used to designate the whole Rocky Mt. system, especially the southern section, where the high, rugged ranges presented an almost impenetrable barrier to westbound explorers and settlers."
4. Sort of a hilltop. On the western side of that line, rainfall flows into the Pacific Ocean, probably through the Colorado or Columbia River systems. On the east side of the Divide, rainfall flows into the Atlantic, by way of either the Great Lakes (to the Atlantic via the St Lawrence) or the Missouri/Mississippi/Ohio river system (to the Gulf of Mexico.) There are other rivers, too; I forget how the Rio Grande works. The Divide snakes around all kinds of strange ways, so the 'east' and 'west' are only approximate.
5. A continental divide is a line of elevated terrain which forms a border between two watersheds such that water falling on one side of the line eventually travels to one ocean or body of water, and water on the other side travels to another, generally on the opposite side of the continent. Because the exact border between bodies of water is usually not clearly defined, the continental divide is not always definite for any continent (The International Hydrographic Organization's publication Limits of Oceans and Seas defines exact boundaries of oceans, but it is not universally recognized). Moreover, some rivers empty into deserts or inland seas, and thus do not end up in the oceans.
6. A divide separating river systems that flow opposite sides of a continent in this case from Alaska to Mexico.
7. isnt that the big desert tha tcuths north america essentially in two, east and west?
8. Continental Divide or Great Divide is the name given to the North American portion of the mountainous ridge which separates the watersheds that drain into the Pacific Ocean from, 1) those river systems which drain into the Atlantic Ocean (including those which drain via the Gulf of Mexico), and 2) along the northernmost reaches of the Divide, those river systems which drain into the Arctic Ocean. A secondary, non-mountainous divide further separates other river systems that drain into the Arctic Ocean (including those which drain via Hudson Bay, James Bay, and Ungava Bay) from those which drain into the Atlantic Ocean (including those which drain via the Great Lakes and Saint Lawrence Seaway). The divide begins at Cape Prince of Wales in Alaska. It runs northeast-/eastward across the north of the state into the Yukon Territory, Canada, where it turns south and travels through British Columbia (forming part of the B.C.-Alberta boundary), in Canada; then through Montana (forming part of the Montana-Idaho boundary), Wyoming, Colorado, and New Mexico, in the United States; then along the crest of the Sierra Madre Occidental through the Mexican states of Chihuahua, Durango, Zacatecas, Aguascalientes, Jalisco, Guanajuato, México and the Distrito Federal, Morelos, Puebla, Oaxaca, and Chiapas; thence through southern Guatemala, southwestern Honduras, western Nicaragua, and western or southwestern Costa Rica, and southern Panama.

10. The Continental Divide is the line in the Rockies that marks the watershed line. Water falling as rain to the west of the line will eventually wash into the Pacific Ocean. Water falling as rain to the east of it will eventually wash into the Atlantic Ocean (or the Gulf of Mexico, which is really a part of the Atlantic Ocean).
