Oceans

During the voyage they went through different oceans : Altantic Ocean ,Pacific Ocean and Indian Ocean.In this waters they found shelter sometimes and storms more frecuently than shelter.They also discovered new territories and they got spices.
Thye also went through different seas and also gave them names.






  • 1. Atlantic Ocean:

Covering about one-fifth of the planet's surface, the Atlantic is the world's second largest ocean. To the West are the Americas, and Europe and Africa lie to the East. The Earth's longest mountain chain, the Mid-Atlantic Ridge, dominates the ocean's underwater landscape. In places, the ridge rises above the water as volcanic islands, such as Iceland and the Azores. The deepest part of the Atlantic, the Puerto Rico Trench, plunges to -8,605 metres.
Sice the Portuguese and Spanish explorers began to cross the Ocean from Europe to America in the 15 century, the Atlantic has been one of the world's major transport structures.The Atlantic is rich in natural resources and it is also a source of food to many territories.

*Nowadays: Today, ships carry bulk goods, such as oil, grand and iron, between the ocean's many international ports. The Atlantic is rich in natural resources. The shallow areas along the coast have deposits of oil and gas, and in recent years, offshore oil and gas reserves have been exploited in the Gulf of Mexico, the Niger Delta and the North Sea. Sand, gravel and shell deposits are mined by the USA and the United Kingdom for use in the construction industry . The ocean is also a vital source of food . Most of the Atlantic coastal countries fish in its waters, but in the North Atlantic, stocks of cod, herring and haddock have reduced by overfishing. The ocean's enviroment is also threatened by pollution. Oil is discharged into the water by ships and drilling rigs. Industrial waste, fertilizers and sewage enter the Atlantic at the coasts, particularly in the Mediterranean, Baltic and North Sea regions, and of the USA, southern Brazil and eastern Argentina. A number of countries are trying to reach and agreements to tackle some forms of pollution.

  • 2.Pacific Ocean:


Stretching about one-third of the Earth's surface, the Pacific is the planet's largest ocean. It extens east from Japan (called Cipango in the past) to the Americas, and south from the Arctic Ocean to Antarctica. The ocean's floor is generally deeper in the west than in the east, and at its deepest point, the Mariana Trench, the Pacific plunges to -11,034 metres.

The many thousands of islands scattered across the Pacific Ocean were created by volcanic eruptions. Some of these islands became fringed with coral, and the islands eventually dropped back into the sea, leaving circles of coral, or atolls. A string of active volcanoes, known as "The Ring of Fire", surrounds the ocean. the Pacific region is plagued by tropical storms called typhoons. The area is also prone to tidal waves, which are caused by volcanic eruptions or underwater earthquakes.

The people of the Pacific mainly grow food for their own consumption, altough afew islands grow crops, such as coconuts and oil palms.

Palm-fringed beaches, spectacular coral reefs and a warm sunny climate are characteristics of the climatic conditions of the islands of the Pacific Ocean.















*Nowadays: Coconuts and oil palms are mainly for export, many of the small islands relly heavily on fishing for much-needed foreign income. These fish industries tend to be small and are forced to compete with the large fishing fleets of Japan and he Russian Federation. The islands of the Pacific have become popule tourist destinations because of their climate.

First name given to the Pacific Ocean: The Pacific Ocean was called the Ladies' sea at first by Magellan's expedition because its waters were so calm that even "the delicated and soft hands of a woman could manage the boats of the expedition in its waters".

  • 3.Indian Ocean:


From the Coast of Africa in the west to Australia and the islands of the southeast Asia in the east, the Indian Ocean measures almost 10,000 km across at its widest point. Under the water are three ridges that form an upside-down 'Y' shape. The ridges mark where three continental plates meet. Here, volcanic activity is common.

The climate of the Indian Ocean varies according to latitude. The regions in the north, near India, have a warm climate. In the south, freezing temperatues have crated pack ice and icebergs. Monsoon winds bring heavy rainfall to many coastal countries. They also have an effect on the ocean's currents, which reverse direction completely between March and August.

For thousands of years, the Indian Ocean has provided important trade routes between the eastern and western parts of the world. Among the first traders to sail its waters were the ancient Egyptians, who travelled salong the east of Africa coast more than 4,000 years ago. In the 15th century, European explorers made pioneering journeys across the Indian Ocean to Asia. They were soon followed by merchants who brought back silks, spices and tea from India and China.

*Nowadays: Today, huge tankers carry oil from the Persian Gulf to many of the ocean's international ports. A large number of these boats travel along the Red Sea and through the Suez Canal to reach Europe.
