Which ocean is about half the size of the Pacific and covers roughly 20% of Earth’s surface?

Explanation:
Understanding the relative size of the oceans helps. The Pacific Ocean is the largest, covering about 30% of Earth’s surface. The Atlantic is smaller, covering about 20%, which is roughly half of the Pacific’s extent. The Indian Ocean is smaller still (around 14%), and the Southern Ocean is the smallest (about 6%). So the Atlantic Ocean best fits the description of being about half the size of the Pacific and covering roughly 20% of Earth’s surface.
