If you build a campfire, you start with a large stack of sticks and logs. As the fire burns, the stack slowly shrinks. By the end of the evening, all that is left is a small pile of ashes. What happened to the matter that you started with? Was it destroyed by the flames? It may seem that way. What do you think happened? The truth is that the same amount of matter still exists. The wood changed not only to ashes, but also to carbon dioxide, water vapor, and other gases. The gases floated off into the air, leaving behind just the ashes. Although matter was changed, it was not created or destroyed. Because the same amount of matter still exists, we can say that matter is conserved. You may wonder how it can be conserved if something is now missing? Assume you had measured the mass of the wood before you burned it. Assume you had also trapped the gases released by the burning wood and measured their mass and the mass of the ashes. What would you find? The ashes and gases combined have the same mass as the wood you started with. This example illustrates the law of conservation of mass.

Question: "What happened to the wood?"

Response: "They get converted to water vapor, carbon dioxide and other gases"

A: yes

When a stream or river slows down, it starts dropping its sediments. Larger sediments are dropped in steep areas. Some smaller sediments can still be carried by a slow moving stream or river. Smaller sediments are dropped as the slope becomes less steep. Alluvial Fans In arid regions, a mountain stream may flow onto flatter land. The stream comes to a stop rapidly. The deposits form an alluvial fan. Deposition also occurs when a stream or river empties into a large body of still water. In this case, a delta forms. A delta is shaped like a triangle. It spreads out into the body of water.

Question: "Are larger sediments dropped in steeper or less steep areas than smaller sediments in the same stream?"

Response: "Least steep areas"

A: no

Defeated last month for re-election, Gov. Roy Barnes announced Tuesday that he will spend his first six months out of office as an unpaid attorney for the Atlanta Legal Aid Society, where he will represent poor people. "One day I'll probably do some legal work that I will charge a handsome fee for - at least I hope there are those that are still willing to pay," he told reporters. "But for now, I think it is important to fulfill my duty as a lawyer to help those who need it the most, to speak for those who cannot speak for themselves and to defend those whose life and livelihoods depend on it," he said. Previous governors have gone to prestigious law firms, joined corporate boards or returned to thriving businesses. "I don't think I've ever heard of anybody doing this before," Emory University political science professor Merle Black said. "If he's actually going to represent individuals for that organization, they're going to get great representation. You're going to get some powerful legal muscle there," Mr. Black said. Mr. Barnes said he already has his first case, but he wouldn't say what it is. Atlanta Legal Aid provides civil services to poor people in five metro Atlanta counties. Mr. Barnes said he was hoping to send a message to other lawyers. "This privilege to practice law is just that - it's a privilege. And it comes with a cost and it comes with a bill . We as lawyers have a responsibility to make sure that everyone, regardless of whether they can afford it or not, has quality representation. And if we don't do that, then we're not much of a profession," he said. Steven Gottlieb, the society's executive director, said, "I can't imagine anything that could be better than to have the governor of the state, in his first act as a private citizen, donate six months of his time to represent poor people .

Question: "Where did Roy Barnes decide to work for his first 6 months out and what do they do?"

Response: "Help poor people"

A:
yes
