Millions of years of weathering, erosion, and riverine sediment deposition have contributed to creating the sloping continental rises that are characteristic of the Atlantic basin. The Atlantic Ocean is saltier than the Pacific, which makes the water denser. It moves more like a conveyer belt that's driven by changes in temperature and salinity over large areas. Some scientists point to climate change and melting glaciers while others argue it is cyclical. Let us know if you have suggestions to improve this article (requires login).

The water temperature in the Atlantic is also greatly affected by currents, most notably the Gulf Stream. Some scientists are concerned that if cold Arctic waters become warmer, the temperature difference will not be enough to drive ocean circulation at the same rate it has been moving. A less arbitrary method involves drawing a line eastward from Greenland to Iceland along the shallow Greenland-Iceland Rise and from Iceland to the Faroe Islands along the Faroe-Iceland Rise and then northward from the Faroes along the relatively shallow bottom features of the Voring Plateau to the west coast of Norway at a point near 70° N. Perhaps a more appropriate method for determining this boundary is by following the division between the distinctive Arctic and Atlantic water masses: the relatively warm and saline waters of the Norwegian Sea are assigned to the Atlantic, and the cold, lower-salinity waters of the Greenland Sea to the Arctic. Rocky coast of Labrador, Canada, on the Labrador Sea, an embayment of the northwestern Atlantic Ocean.

The Atlantic Ocean is the second-largest of the Earth's oceans. The ocean’s breadth from east to west varies considerably. Because the ocean's conveyer belt influences weather over the land masses bordering the Atlantic, a change to the rate of circulation could affect summers, winters, and natural disasters, from the U.S. to Europe. Together, the different densities, currents, and temperatures create the rough sea that makes Cape Horn famous. Hurricanes are fueled by warm waters, and warmer Sahara summer winds drive some of the biggest hurricanes seen in the U.S. Those that form off the coast of Africa must survive wind shear (horizontal winds) to hit the East Coast with full force.
