Problem: Heat supplies the energy that causes motion. The deeper you go into toward the Earths core, the hotter it gets. At the core it is really hot. All that heat tries to rise toward the surface. In the Mantle, the rock is partially melted and is able to move. As it is heated, the material in the mantle moves toward the surface. As the mantle material rises, it cools. When it reaches the Earths crust, it is mostly stopped. A little of the material can break through the surface, but not all. Instead, it begins to move horizontally. The mantle material moves horizontally away from a mid-ocean ridge crest. Toward the surface, the mantle material starts to cool. As it cools it sinks back down into the mantle. These areas are where deep sea trench occur. The material sinks back down to the core. The system operates like a giant conveyor belt. The motion due to heating and cooling is called convection.

Question: "Where do sea trenches occur?"

Answer: "Crust"
Answer: no

Problem: The grant also will help victims go through court proceedings after losing a job or being evicted because of an abuser's actions, Xanthopoulos said. "It's going to help the victims, but it's also going to help their children," he said. More than 270 domestic violence assaults in Madison County were reported last year, according to Tennessee Bureau of Investigation statistics. In Jackson, more than 730 domestic violence assaults were reported last year, according to records. "Domestic violence is certainly on the increase and we need to do something to curve that. I see this as helping that," Madison County Sheriff David Woolfork said of the grant. Domestic violence accounted for five of 12 murders in 2001 in Jackson, police have said. And the increase in calls prompted Jackson Police Chief Rick Staples in March to form a focus group to determine if police officers need to make changes in their response to domestic calls.

Question: "How can the grant help children of domestic abuse victims?"

Answer: "The grant will provide the children government aid"
Answer: no

Problem: 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.

Question: "How does one buy durable goods to reduce resource use?"

Answer: "Choose items that are well made so they will last longer"
Answer:
yes
