THE ATLANTIC OCEAN has been a key avenue of trade and travel. Stretching from the Arctic Circle to Antarctica, the Atlantic Ocean is bordered by the Americas to the west and Europe and Africa to the east. It's more than 41 million square miles, the second-largest ocean on Earth after the Pacific Ocean.
Scientists and geographers broadly separate the Atlantic in terms of NORTH AND SOUTH. The North Atlantic and South Atlantic each have distinct ocean CURRENTS that influence weather around the world.
THE PACIFIC OCEAN is the largest and deepest ocean on Earth. It spans 60 million square miles from California to China, and in certain regions extends tens of thousands of feet below the surface of the water.
To get a sense of just how immense the Pacific Ocean is, you could put all of Earth's landmasses together, and the Pacific would still be LARGER. Scientists and geographers broadly separate the Atlantic in terms of north and south. The North Atlantic and South Atlantic each have distinct ocean currents that influence weather around the world.
THE ARCTIC OCEAN is Earth's northernmost body of water. It encircles the Arctic, and flows beneath it. Most of the Arctic Ocean is covered by ICE throughout the year—although that is starting to change as temperatures climb. Though it's the world's smallest ocean—spanning 6.1 million square miles—the Arctic is now receiving unprecedented international attention. Scientists are racing to understand how warming temperatures will alter Arctic Ocean waters—and by extension the rest of the climate—and world leaders are racing to control newly opening waters.
The Arctic Ocean is WARMING faster than anywhere else on Earth and feeling the onslaught of climate change.
