Section B
Passage 1
The earth is composed of several layers. The top layer of the earth is called the earths crust. The earths crust is divided into seven sections. These sections are called plates.
When two plates push against each other, or when two plates rub against each other, an earthquake will occur. An earthquake causes the ground above the plate to shake. The shaking is caused by the motion of two plates.
Earthquakes are likely to happen at the boundaries of the earths plates. Each of these plates is about 70 kilometers thick. Lets take a look at the general boundaries of one of these seven major plate.
Take the North American plate for an example. The left boundary of this plate is the west coat of North America and the east boundary of this plate is through the middle of the Atlantic Ocean. That is, this plate extends from the west coast of North America to the middle of the Atlantic Ocean.
Questions 11 to 13 are based on the passage you have just heard.
11. What is the top layer of the earth called?
12. How many major sections is the earths crust divided into?
13. Which of the following is the left boundary of the North American plate?
