5What are chokepoints?Hint: In your history class they might be called “bottlenecks.”But geographers call them “chokepoints.”Now, take a minute and imagine what a chokepoint or a bottleneck might look like.
6Chokepoints or bottlenecks? Have you ever had trouble getting catsup out of the bottle? What caused the trouble? Was it partially caused by trying to get something too thick through too small a place?
7Chokepoints or bottlenecks? Have you ever wondered how they got those ships into those bottles?How does something that big go through the narrow space at the top of the bottle?After slide 7, think about the shape of the bottle and write a description of a chokepoint on your paper.
8Chokepoints or bottlenecks? Why do people choke?Sometimes it’s because something too large got stuck in their throat.
9ChokepointsIt’s just the same when people try to transport goods around the world.Sometimes countries are trading one good for another.Sometimes countries are transporting soldiers or armaments to battle sites.The control of these narrow passageways is critical. Whoever has the control is in power.
10ChokepointsI have the power.I control the chokepoint.
11Corinth Canal (Greece) There are approximately 200 straits ( narrow bodies of water connecting two larger bodies of water) around the world, but only a handful are known as chokepoints.On your paper define “chokepoint.”
12ChokepointsA chokepoint is a strategic strait or canal which could be closed or blocked to stop sea traffic.The Suez Canal and the Straits of Hormuz (pictured on the map) are examples of chokepoints.Strait of HormuzSuez CanalMake any adjustments to your definition that are needed.
13CHOKEPOINTS OR BOTTLENECKS ? With the rise of industrial Europe and seaborne trade, entrepreneurs thought of building a canal to connect the Red Sea with the Mediterranean Sea directly, thus saving time either from sailing around Africa or transporting freight across the Suez Peninsula.
14SUEZ CANALThe Suez Canal was completed in 1869 under the leadership of a French company under de Lesseps. European capital (money) built it and operated it.Why would European companies be willing to fund the building of the canal? How would it make them more competitive?Write your answer on your paper.
15SUEZ CANALMediterranean SeaThe Suez Canal brought a new era of European influence in Pacific Asia by reducing the journey from Asia to Europe by about 65,000 km. The region became commercially accessible and colonial trade expanded.Suez CanalRed Sea
16ChokepointsThe Suez Canal is only 101 miles long but was built across the Egyptian desert. It is one of the most significant maritime “shortcuts” ever built by man.Construction of the Suez Canal
18IMPACT OF THE SUEZ CANAL Shortened the route around Africa by 4,000 miles.
19SUEZ CANAL Shortened the route around Africa by 4,000 miles. Saved two weeks of shipping time.
20SUEZ CANAL Shortened the route around Africa by 4,000 miles. Saved two weeks of shipping time.If you can shorten your shipping time, you can ship more items in the same amount of time that it used to take.
21SUEZ CANAL Shortened the route around Africa by 4,000 miles. Saved two weeks of shipping time.If you can shorten your shipping time, you can ship more items in the same amount of time that it used to take.Tonnage shipped jumped from 500,000 tons to 3,500,000 tons in ten years after the Suez Canal opened.
22This allowed the Europeans to take a greater interest in the Asian markets than ever before. British control of the canal was viewed as the “Lifeline of the Empire” because it allowed the British quicker access to the colonies in Asia and Africa.On your paper, write down what you think is the most important impact of the Suez Canal. Justify your answer.
23Strait of Gibraltar Has long been fought over Has been held by the Phoenicians, Romans, Visigoths, and the MoslemsThe British won the Battle of Trafalgar defeating Napoleon

27OIL DEPENDENCYFor the past 50 years, one of the main sources of energy used by developed and developing nations has been oil.For nations with little of this resource, disruption of the availability of oil or a large price increase, causes economic or political problems.On your paper, write down two effects of closing a chokepoint.
29SECURING THE SUPPLY: STRATEGIC POINTS OF CONCERN For centuries, straits such as Gibraltar have been protected by international law.In 1982, the Law of Sea Conventions further protected the international access for nations to sail through straits and canals.On your paper, explain why straits would be protected by international laws.

31Suez CanalClick on button to return to map.It is the only sea route between the Red Sea and the Mediterranean Sea.With the Middle East tension, the Suez Canal is a prime target for many nations. In 1967, the Arab-Israeli War shut down the canal for 8 years.A third of the cargo is oil.

33STRAIT OF HORMUZ Closely monitored by the U.S. military and its allies Critical point in the lifeline flow of oil from the Persian Gulf area.

35THE BOSPORUS STRAIT Joins the Black Sea and the Sea of Marmara Russians and Turks have fought many battles over this strait. Turks are now citing environmental concerns as an excuse to restrict Russian access to the strait.
37Strait of MalaccaTankers pass through this strait bordered by Indonesia and Malaysia.Located in the Indian Ocean, this strait is a shortcut for oil tankers traveling between the Middle East and the oil-dependent nations of the Pacific Rim (especially Japan.)More than 50,000 ships pass through this strait yearly.Click button to return to map

40Let’s recap what we know about chokepoints. A chokepoint is a strategic strait or canal which could be closed or blocked to stop sea traffic.The Suez Canal and the Straits of Hormuz (pictured on the map) are examples of chokepoints.Strait of HormuzSuez Canal
41Now, review what else you know. If a chokepoint is closed, it affects world trade patterns, the economy and politics.That can lead to higher prices and/or war.Keeping these straits or chokepoints open is very important.The control of these narrow passageways is critical. Whoever has the control is in power.
42? Complete a flow chart showing these effects. Closure of Strait of HormuzU.S. and Japan scramble for oil.?
43Which best fits in the last box of the flow chart? A. Saudi Arabia pipes the oil to theRed Sea.B. The U.S. sends in troops and aircraft totake over the Strait of Hormuz.C. Diplomatic pressure makes Turkeyopen the Strait.D. The price of oil products goes downworldwide.
44Yes, the correct answer is B Yes, the correct answer is B. The United States sends in troops to open the Strait of Hormuz.A is incorrect. Saudi Arabia might be able to pump more oil to the Red Sea but the quantity would not be sufficient.C is incorrect. Turkey controls the Bosporus Strait, not the Strait of Hormuz.D is incorrect. The price of oil products would go up significantly around the world.
45Congratulations, you have finished the tutorial on chokepoints. Now see if you can answer two more questions on your worksheet.Have your teacher check your answers.You should ace this part of the TAKS now. You have the power.
