Geography

Indian Ocean

The Indian Ocean is a body of saltwater that covers about one-fifth of the world's total ocean area. It is the smallest ocean; it is geologically the youngest and physically the most complex of the three major oceans in the world. It stretches over 10,000 km between the southern tips of Africa and Australia and, without its marginal seas, has an area of approximately 73,440,000 square km. The average depth of the Indian Ocean is 12,990 3,960 meters, and its deepest point is in the Sunda Deep of Java Trench off the south coast of the island of Java in Indonesia.

What is the Indian Ocean?

The Indian Ocean is the third largest body of water on the planet, covering about one-fifth of the earth's total water and one of the youngest in terms of formation.

Location of the Indian Ocean

It lies between East Africa, Southern India and Oceania and Northern Antarctica. The Indian Ocean is bounded by Iran, Pakistan, India and Bangladesh to the north; the Malay Peninsula, the Sunda Islands of Indonesia and Australia to the east; Antarctica to the south; and Africa and the Arabian Peninsula to the west. In the southwest it joins the Atlantic Ocean to the south of the southern tip of Africa, and to the east and southeast its waters mix with those of the Pacific Ocean.

History of the Indian Ocean

It is believed that the first civilizations developed around its waters. During the first dynasty of Egypt, different expeditions left to navigate its waters finding gold and myrrh. The first trade between Mesopotamia and the Indus Valley took place in the Indian Ocean. The Indonesian peoples crossed it to settle in Madagascar. The first Greek to cross the ocean to India was Hippalus. Trade relations between Egypt and South India developed there. The first European navigator who sailed its waters was Vasco de Gama, dominating the trade.

Characteristics

The most outstanding characteristics of the Indian Ocean are as follows:

Indian Ocean islands

The islands we can find in the Indian Ocean are the following:

Weather

In its southern part the climate is very stable and in its northern part, monsoons can be found. Monsoon winds thus affect the climate in the northern part of the equator. In the southern hemisphere, the winds are less intense, but there are storms that occur in the summer that are quite strong.

When drastic changes occur in the monsoons, cyclones hit the coasts.

Fauna

The marine fauna of the ocean is very limited because in ocean does not possess the necessary quantities of phytoplankton to give nutrients to the fish. In its northern part, you can find more marine species that are a source of exploitation mainly for domestic consumption. Shrimp and tuna are two species that can be found in the area. Among the marine animals that inhabit the area and are already in danger of extinction are turtles and whales.

Flora

Due to its climate, there is little vegetation, but the most common are teak and cane, which are typical flowers of the area. On its islands we can find citrus lemon, which is a flowering tree that produces lemon. The tiliaceus hibiscus is an ornamental tree with flowers native of the coasts of the Indian Ocean. Teak is used for the construction of doors, windows and furniture. The common cane is a perennial herb, with high leaves which they use to make baskets and reeds for instruments.

Importance

In the Indian Ocean we can find many oil and natural gas deposits. It is an important source of fishing, sand and gravel, which are used by different sectors of industry. It has four important routes for navigation which allows to transport goods from one place to another, mainly the routes between the Middle East, Africa and Asia with Europe.

Why it is called the Indian Ocean

The Indian Ocean was named by Portuguese explorer Fernando de Magallanes during one of his expeditions. Its name was given because it is found bathing the coasts of Indonesia and India.
