Which ocean is the second largest in the world?

The Atlantic Ocean is recognized as the second largest ocean in the world, following the Pacific Ocean, which is the largest. The Atlantic Ocean covers an area of approximately 106.5 million square kilometers (41.1 million square miles), making it significantly smaller than the Pacific, which spans around 168.7 million square kilometers (65.7 million square miles).

Understanding the sizes and positions of the world’s oceans is crucial in geography, as it helps in grasping global weather patterns, ocean currents, and the distribution of marine biodiversity. The Atlantic Ocean plays a significant role in global trade and transportation, connecting various continents such as North America and Europe.

The other options do not surpass the Atlantic in size; the Indian Ocean, while being the third largest, covers about 70.6 million square kilometers (27.2 million square miles), and the Arctic Ocean is the smallest, at approximately 15.6 million square kilometers (6.1 million square miles). Thus, the Atlantic Ocean's ranking as the second largest is well-established in geographical studies.
