With the development of modern industry, many of the goods and machines we need and use in our daily lives are creating a number of waste products which upset the

Many of these waste products can be prevented if people pay more attention, but clearly while more and more new goods are produced and made complex, there will be new dangerous wastes to be thrown away, for example, the waste products from nuclear power stations. Many people, th
7、erefore, see pollution as only part of a larger and more complex problem.There is no doubt that much of the pollution caused could be controlled if only companies, individuals and government would make more efforts.

A fault is a fracture(断裂)in the crust(地壳)of the earth along which rocks on one side have moved relative to those on the other side. Stress
13、es in the earths outer layer push the sides of the fault together, builds up and the rocks slips suddenly, releasing energy in waves that travel through the rock to cause the shaking that we feel during an earthquake.Earthquakes tend to be concentrated in narrow zones. There are 7 major crustal plat
14、es on earth, about 80 km(50 miles)thick, all in constant motion relative to one another. They move at between 10 and 130 mm(from less than one half to 5 inches)per year.It is estimated that there are several million earthquakes in the world each year. Many of these earthquakes go undetected because
15、they occur in remote areas or have very small magnitudes(震级). The USGS Earthquake Info Center locates 12 000 to 14 000 earthquakes each year(about 35 per day). On average, about 60 earthquakes per year are classified as significant, with 19 classified as major. A significant earthquake is one of mag
