The correct answer is Pacific Ocean.

Key Points

  • The Pacific Ocean is the largest and deepest ocean on Earth, covering more than one-third of the Earth's surface.
  • It spans approximately 63 million square miles, making it bigger than all the landmasses combined.
  • The Pacific Ocean is located between Asia and Australia to the west, and North and South America to the east.
  • It plays a critical role in global climate systems, particularly in weather patterns like El Niño and La Niña.

Additional Information

  • Pacific Ocean accounts for about 46% of the Earth's surface water and extends across a vast portion of the globe.
  • The ocean's size is so vast that it contains more than half of the world's surface water.
  • The Pacific's size and depth influence a variety of ecosystems, from tropical coral reefs to deep-sea trenches.
  • Indian Ocean, the Arctic Ocean, and Atlantic Ocean are smaller compared to the Pacific, each contributing to Earth's hydrosphere but none covering as much of the planet's surface.
  • Not only does the Pacific Ocean contain a massive amount of water, but it also has significant economic and strategic importance due to shipping routes, natural resources, and global trade.
  • The Pacific is also home to the Great Barrier Reef and many other unique marine ecosystems, making it crucial for biodiversity conservation.
