A very long pipeline starts at the northern coast of Alaska and runs to the southern coast. It is over 800 miles long. There were many gold rushes in Alaska.

  * There are large banana farms in Ecuador. Oil is one of Ecuador's natural resources. Ecuador uses the United States dollar for money. Its currency used to be the sucre.
+ Lubricant: Oils :: Materials
  * Oil is discovered in Saudi Arabia.
+ South America, Natural resources: Gondwana
  * Brazil's soil is very good for growing coffee. A great number of minerals have been found. Few, however, have been mined. Among those that were mined are iron, manganese, gold, and gemstones. The tropical forests are rich in valuable trees, like mahogany, ebony, and rubber. Oil is also a resource in some places.
+ Viscosity index: Fuel
  * Lubricating oil is meant to reduce friction between two surfaces. If it is too viscous the oil will be thick and sticky and need too much energy to keep the parts moving. If the oil is too thin, then the parts will rub together and create friction. What is needed is an oil that has just the right amount of viscosity to keep the two surfaces apart. Oil becomes less viscous as the temperature goes up. In an automobile engine, the oil needs to be viscous at a range of temperatures. The best oils, with a high viscosity index score, will keep their viscosity the same across the temperature range.
