Indian Ocean
The ocean between Africa, Asia, and Australia.
The Indian Ocean is the world's third-largest ocean, stretching between Africa, Asia, and Australia. It's smaller than the Pacific and Atlantic Oceans but still covers about 20 percent of Earth's water surface.
For thousands of years, the Indian Ocean connected ancient civilizations through trade. Ships from India, Arabia, East Africa, and Southeast Asia crossed these waters carrying spices, silk, gold, and ideas between continents. Monsoon winds, which blow predictably in different directions depending on the season, helped sailors navigate these routes long before modern technology existed. Merchants learned to sail with the monsoons, traveling one direction for half the year and returning when the winds reversed.
The Indian Ocean touches three continents and contains thousands of islands, including Madagascar (the world's fourth-largest island), Sri Lanka, and the Maldives. Its warm waters support incredible marine life, including many species of whales, dolphins, and sea turtles. Coral reefs throughout the region provide homes for countless colorful fish.
Today, the Indian Ocean remains one of the world's busiest shipping routes. Massive container ships and oil tankers cross it daily, carrying goods between Asia, Africa, and the Middle East, and on to markets around the world.
