  1. The World Oceans

  2. Arctic Ocean • A smooth, pale-blue layer of polar pack ice edged by jagged chunks of floating ice covers much of the frigid waters • With an area of 12 million square kilometers (5 million square miles), smallest ocean • More than five times smaller than the Indian and Atlantic oceans.

  3. Atlantic Ocean • Passive margin ocean with most of its geological activity centered along the Mid-Atlantic Ridge. • Most of its coastal regions are low and geologically quiet. • Area of 82 million square kilometers (32 million square miles). • Average depth of 3,600 meters (11,812 feet). • Its greatest depth is in the Puerto Rico Trench at 8,605 meters (28,231 feet).

  4. Indian Ocean • The smallest of the three major oceans • Covers an area of about 73 million square kilometers (about 28 million square miles) - about 20 percent of the total area covered by the world's oceans. • Average depth of the Indian Ocean is 3,890 meters (12,762 feet). • Deepest point is the Java trench, at 7,725 m.

  5. Pacific Ocean • The world's largest geographic feature • Covers more than 166 million square kilometers (more than 64 million square miles)—about one-third of the earth's surface • The area of the Pacific is greater than that of all of the continents combined, and it makes up nearly half of the area covered by the earth's oceans.

  6. Southern Ocean • Designated as an ocean in 2000 • A large circumpolar body of water totally encircling the continent of Antarctica. • Lies between 60 degrees south latitude and the coast of Antarctica, and encompasses 360 degrees of longitude. • The fourth largest of the world's five oceans (after the Pacific Ocean, Atlantic Ocean, and Indian Ocean, but larger than the Arctic Ocean).
