Antarctica is in the most southern part of the world. It is like nowhere else on the earth. It is much larger than Europe, and nearly twice the size of Australia. Antarctica is the coldest and windiest place in the world, even colder and windier than the North Pole. In summer, the sun shines for twenty-four hours a day, but in winter it’s completely dark for about three months. Very few plants grow there, but there is some wildlife, including whales, seals and penguins.
When Captain James Cook traveled around Antarctica in the 1770s by ship, he found no one living there. Today, a few scientists work in Antarctica, but they only spend a short time there.
Many scientists are studying the ozone layer, which is getting thinner and thinner worldwide. The biggest “hole” is above Antarctica, and weather there is getting warmer. Scientists think that this cold and lonely place can teach us a lot about the earth and how to keep the earth safe.

Oil is to find, because it is deep under the earth. Today, however, we have many to find oil. One tool measures(测量) the pull of gravity(重力). Places where gravity is weaker are more likely to have oil. tool measures sound waves. Sound waves travel different kinds of rocks at different speeds. We can use to find the rocks that have oil in them.
