Q: Earthquakes seemed to outline a special feature of earth's crust. Earthquakes let scientists know where the crust was moving. This led to the discovery that the Earths crust was broken up into regions, or plates. Earthquakes happen most often along these plate boundaries. This was evidence that continents can move. The movements of the plates are called plate tectonics. The Earths crust is divided into plates. There are about a dozen large plates and several small ones. Each plate is named for the continent or ocean basin it contains. Scientists know he plates are in motion. They now know the direction and speed of this motion . Plates dont move very fast. They move only a few centimeters a year. This is about the same rate fingernails grow. So you might wonder, what could cause this motion? What supplies the energy to cause this change? <sep>How fast do plates move?<sep>A few centimeters a year

A: Yes

Q: Reducing resource use means just what it says using fewer resources. There are lots of ways to reduce our use of resources. Buy durable goods. Choose items that are well made so they will last longer. Youll buy fewer items in the long run, so youll save money as well as resources. Thats a win-win! Repair rather than replace. Fix your bike rather than buying a new one. Sew on a button instead of buying a new shirt. Youll use fewer resources and save money. Buy only what you need. Dont buy a gallon of milk if you can only drink half of it before it spoils. Instead, buy a half gallon and drink all of it. You wont be wasting resources (or money!) Buy local. For example, buy local produce at a farmers market, like the one in Figure 2.20. A lot of resources are saved by not shipping goods long distances. Products bought at farmers markets use less packaging, too! About a third of what we throw out is packaging. <sep>How is it a win-win to buy durable goods?<sep>You will have more things at a lower cost

Q: Howland talked but little on their way back to camp. The scene that he had just witnessed affected him strangely; it stirred once more within him all of his old ambition, all of his old enthusiasm, and yet neither found voice in words. He was glad when the dinner was over at Thorne's, and with the going of the mail sledge and the senior engineer there came over him a still deeper sense of joy. Now _he_ was in charge, it was _his_ road from that hour on. He crushed MacDonald's hand in a grip that meant more than words when they parted. In his own cabin he threw off his coat and hat, lighted his pipe, and tried to realize just what this all meant for him. He was in charge--in charge of the greatest railroad building job on earth--_he_, Jack Howland, who less than twenty years ago was a barefooted, half-starved urchin peddling papers in the streets where he was now famous! And now what was this black thing that had come up to threaten his chances just as he had about won his great fight? He clenched his hands as he thought again of what had already happened--the cowardly attempt on his life, the warnings, and his blood boiled to fever heat. That night--after he had seen Meleese--he would know what to do. But he would not be driven away, as Gregson and Thorne had been driven. He was determined on that. <sep>How did Jack feel after dinner and why did he feel this way?<sep>Jack was sorry to be replacing Thorne

No
