The Atlantic Ocean
Understanding the second-largest ocean on Earth
Introduction
The Atlantic Ocean is the second-largest ocean on Earth, covering about 20% of the planet's surface. It stretches between the Americas to the west and Europe and Africa to the east, playing a critical role in global climate and weather patterns.
Geography
The Atlantic Ocean spans approximately 41 million square miles (106 million square kilometers) and is divided into several regions, including:
- North Atlantic
- South Atlantic
- Caribbean Sea
- Gulf of Mexico
The ocean has various notable features, such as the Mid-Atlantic Ridge, which is the longest mountain range in the world, and the Bermuda Triangle, infamous for unexplained disappearances of ships and aircraft.
Climate
The Atlantic Ocean influences the climate of the surrounding continents. It is known for its warm Gulf Stream current, which brings milder weather to regions like Western Europe. Conversely, the North Atlantic can experience brutal winters, leading to severe storms.
Marine Life
The Atlantic Ocean is home to a rich diversity of marine life, including:
- Various species of fish, such as cod, haddock, and tuna
- Marine mammals like dolphins, whales, and seals
- Diverse coral reefs, particularly in the Caribbean
- Countless invertebrates and plankton
These ecosystems support significant commercial fisheries and are critical for environmental balance.
Cultural Significance
The Atlantic Ocean has served as a vital link between cultures for centuries. It facilitated trade, exploration, and colonization, actively shaping historical events. Major cities along its coasts, such as New York, London, and Rio de Janeiro, are global cultural and economic hubs.
