Atlantic Ocean
The Atlantic Ocean is the second-largest ocean on Earth, spanning roughly 82 million square kilometers between the Americas and Europe-Africa. It divides the Old and New Worlds, shaping History through trade, migration, and conflict.
Formed during the breakup of the supercontinent Pangaea millions of years ago, the Atlantic remains geologically active. The Mid-Ocean Ridge runs down its center, where new oceanic crust continuously forms. Its waters drive global climate systems, absorbing vast amounts of atmospheric carbon and generating powerful currents like the Gulf Stream.
The ocean teems with life—from microscopic plankton that generate oxygen to massive cetaceans and deep-sea creatures adapted to crushing pressures. Yet it faces mounting threats: acidification, overfishing, and plastic pollution degrade its ecosystems.
Economically, the Atlantic remains vital for fishing, shipping, and energy extraction. Islands like Iceland and Bermuda offer unique environments shaped by Atlantic storms and currents. For centuries, this ocean has symbolized both opportunity and peril—a bridge and a barrier that continues to define human civilization.
