How oil is produced
Today modern exploration methods make it possible to find oil with a 70% success rate. Most of the world’s oil is produced into the crust of the earth. Crude oil is found together with gas, which floats above the oil layer. Sometime gas is extracted together with oil during the drilling process, at other time it is simply burned off when it comes to the surface.
Petroleum industry
In addition to exploring new reserves, drilling and refining oil, the industry must also bring oil products to the consumer.
Price of oil
Many factors can influence the price of oil. Especially wars and conflicts in oil-producing countries can lead to a rise in oil prices. The energy crisis of the 1970s, oil prices and threw the world’s economy into a deep recession.
Oil consumption
Most of the world’s oil is needed in the western world. The United States is the world’s largest oil consumer. It uses up about a fifth of the daily oil production. Japan, the European Union and China are other major consumers of oil.
Environmental effects of oil production
Producing and consuming oil and oil products affects our environment in many ways. It is a major cause of global warming because burning fuel releases carbon dioxide, thus causing the greenhouse effect.
History of oil
The first oil well was created in the middle of the 19th century in Pennsylvania. The automobile boom of the early 20th century led a higher demand of oil. In the second part of the 20th century Saudi Arabia and Russia produced even more than the USA. Today more than 90% of all vehicles are powered by oil products. About 80% of the world’s oil reserves are located in the Middle East. Other notable producers are Venezuela, Great Britain and Indonesia.
What petroleum is made out of
Crude oil consists mainly of hydrocarbons, a combination of hydrogen and carbon. Each deposit of petroleum has a different combination of hydrocarbons, thus making it a thicker or thinner liquid. It also has sulphur, nitrogen and other elements in it.
Elements of language
Words can describe thing, objects or actions. Some words are used to connect parts of a sentence. Languages have rules, called grammar. Sometime grammar is easier, at other time people find it hard to learn all the rules of a language.
Languages in our world
There are about 7000 languages spoken in our world today. Only very few are so called world languages, widely spoken by millions of people, the rest are local languages that are only spoken in certain areas. The most common languages are Mandarin Chinese, English and Spanish.
Changes in language over the ages
Even standard languages change over centuries. English during the time of Shakespeare is much different from the English we speak today.
Future of languages
Many linguists say that Mandarin Chinese will become the new number one language, because it is the mother tongue of over 1 billion people.
