Minerals, Oil Belts and Major Sea Routes
Industry and transport depend on minerals and energy, and the movement of these resources depends on the great sea routes of the world. This chapter brings together the distribution of important minerals such as iron ore, coal, bauxite, copper, gold and diamonds, the petroleum and natural gas belts that power the world economy, and the major shipping routes that connect the producing regions to the markets. Examiners ask about the leading producers of each mineral, the location of the world's oil belts, and the sea routes and canals that carry trade. Because these facts are fixed, the topic rewards careful memorisation.
Important minerals
Minerals are natural substances obtained from the Earth's crust and are the raw material of industry. Iron ore is the backbone of the iron and steel industry, and the leading producers are Australia, Brazil, China and India. Coal, an important source of energy, is produced in largest quantity by China, India, the United States and Australia. Bauxite, the ore of aluminium, is found mainly in Guinea, Australia, Brazil and China. Copper is mined chiefly in Chile, which is the world's largest producer, followed by Peru. Gold is produced in largest quantity by China, Russia and Australia, while diamonds come mainly from Russia and Botswana. Manganese, used in making steel, is found in South Africa, Australia and Gabon. India is rich in iron ore, coal, mica and manganese.
Coal and petroleum
Coal is a fossil fuel formed from buried plant matter and is used mainly for electricity and steel. The largest coal producers are China, India, the United States and Australia, and China also holds the largest reserves. Petroleum, or crude oil, is the most important energy resource of the modern world and also the raw material of the petrochemical industry. The Persian Gulf region holds the largest oil reserves on Earth, and Saudi Arabia is one of the largest producers and exporters of oil. Other leading oil producers include the United States, Russia, Iran, Iraq, Kuwait, the United Arab Emirates, Canada, Venezuela and Nigeria. Natural gas is produced in largest quantity by the United States and Russia. The Organisation of Petroleum Exporting Countries (OPEC) coordinates the policies of many major oil-exporting nations.
The oil belts of the world
The great oil belts of the world include the Persian Gulf belt, the largest of all, covering Saudi Arabia, Iran, Iraq, Kuwait, Qatar and the United Arab Emirates; the North Sea belt between Britain and Norway; the Gulf of Mexico and Caribbean belt, with Venezuela's Lake Maracaibo being especially famous; the Nigeria belt in West Africa; the Ural-Volga and West Siberian belts of Russia; the Alaska belt in North America; and the Gulf of Suez belt in Egypt. Because the largest reserves lie around the Persian Gulf, the Straits of Hormuz and the Suez Canal have become routes of immense strategic importance.
Major sea routes of the world
Since the Industrial Revolution, sea transport has carried the bulk of world trade. The Suez Canal route links Europe with Asia through the Mediterranean and the Red Sea, greatly shortening the voyage that would otherwise go around Africa. The Panama Canal route links the Atlantic and the Pacific Oceans through Central America. The Cape of Good Hope route, around the southern tip of Africa, was historically the main route to Asia and is still used by very large ships. The Strait of Malacca carries much of the trade between the Indian Ocean and East Asia, while the Strait of Hormuz is vital for the export of Persian Gulf oil. Other important routes pass through the Babel-Mandeb, the Strait of Gibraltar, the Bosphorus and the Panama and Kiel canals. Control of these routes has often shaped the politics of the world.
Quick revision
Remember the leading producers: Australia and Brazil for iron ore, China and India for coal, Guinea for bauxite reserves, Chile for copper, China for gold, Russia and Botswana for diamonds. The Persian Gulf holds the largest petroleum reserves, with Saudi Arabia a leading producer, and the United States and Russia lead in natural gas. The main oil belts are the Persian Gulf, the North Sea, the Gulf of Mexico and Caribbean, Nigeria, Russia, Alaska and the Gulf of Suez. The Suez route links Europe and Asia, the Panama route links the Atlantic and Pacific, and the Cape route goes around Africa.
How to prepare this topic
- Learn the leading producer of each important mineral, as these are frequent direct questions.
- Fix the oil geology - the Persian Gulf has the largest reserves and Saudi Arabia is a top producer.
- Locate each oil belt on a world map along with the sea route that serves it.
- Remember the three great routes - Suez, Panama and the Cape of Good Hope - and what each connects.
- Note that the Straits of Hormuz and Malacca are the two most strategic oil and trade passages.
Common exam traps
- Chile, not Brazil, is the largest producer of copper; Brazil leads in iron ore along with Australia.
- The largest petroleum reserves are in the Persian Gulf, while the United States is among the largest producers of oil and gas.
- The Suez route connects Europe and Asia, while the Panama route connects the Atlantic and Pacific.
- The Cape of Good Hope route goes around Africa and is not the same as the Suez route.
- Bauxite is the ore of aluminium, not of iron.
Frequently Asked Questions
Which countries are the leading producers of important minerals?
Australia and Brazil are leading producers of iron ore, along with China and India. China, India, the United States and Australia lead in coal production. Guinea, Australia, Brazil and China produce bauxite, the ore of aluminium. Chile is the largest producer of copper, while China, Russia and Australia lead in gold, and Russia and Botswana are important for diamonds.
Where are the largest petroleum reserves and who are the leading producers?
The Persian Gulf region holds the largest petroleum reserves on Earth, and Saudi Arabia is one of the largest producers and exporters of oil. Other leading producers include the United States, Russia, Iran, Iraq, Kuwait, the United Arab Emirates, Canada, Venezuela and Nigeria. Natural gas is produced in largest quantity by the United States and Russia, and OPEC coordinates the policies of many oil-exporting countries.
What are the major oil belts of the world?
The major oil belts include the Persian Gulf belt, which is the largest of all; the North Sea belt between Britain and Norway; the Gulf of Mexico and Caribbean belt, where Venezuela's Lake Maracaibo is famous; the Nigeria belt in West Africa; the Ural-Volga and West Siberian belts of Russia; the Alaska belt; and the Gulf of Suez belt in Egypt.
What are the major sea routes of the world and what do they connect?
The Suez Canal route links Europe with Asia through the Mediterranean and the Red Sea, the Panama Canal route links the Atlantic and Pacific Oceans through Central America, and the Cape of Good Hope route goes around southern Africa towards Asia. The Strait of Malacca carries trade between the Indian Ocean and East Asia, and the Strait of Hormuz is vital for the export of Persian Gulf oil.
Why are the Straits of Hormuz and Malacca so important?
The Strait of Hormuz is the outlet through which a large share of the world's petroleum from the Persian Gulf is exported, so any disruption there affects global oil supply. The Strait of Malacca is one of the busiest shipping lanes and carries much of the trade between the Indian Ocean and East Asia. Together with the Suez and Panama canals, these passages control a great part of world trade and are therefore of enormous strategic value.
