Question: 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. <sep>Where do sea trenches occur?<sep>Surface

Answer: No

Question: When American 11 struck the World Trade Center at 8:46, no one in the White House or traveling with the President knew that it had been hijacked. While that information circulated within the FAA, we found no evidence that the hijacking was reported to any other agency in Washington before 8:46. Most federal agencies learned about the crash in New York from CNN. Within the FAA, the administrator, Jane Garvey, and her acting deputy, Monte Belger, had not been told of a confirmed hijacking before they learned from television that a plane had crashed. Others in the agency were aware of it, as we explained earlier in this chapter. Inside the National Military Command Center, the deputy director of operations and his assistant began notifying senior Pentagon officials of the incident. At about 9:00, the senior NMCC operations officer reached out to the FAA operations center for information. Although the NMCC was advised of the hijacking of American 11, the scrambling of jets was not discussed. In Sarasota, Florida, the presidential motorcade was arriving at the Emma E. Booker Elementary School, where President Bush was to read to a class and talk about education. White House Chief of Staff Andrew Card told us he was standing with the President outside the classroom when Senior Advisor to the President Karl Rove first informed them that a small, twin-engine plane had crashed into the World Trade Center. The President's reaction was that the incident must have been caused by pilot error. At 8:55, before entering the classroom, the President spoke to National Security Advisor Condoleezza Rice, who was at the White House. She recalled first telling the President it was a twin-engine aircraft-and then a commercial aircraft-that had struck the World Trade Center, adding "that's all we know right now, Mr. President." At the White House, Vice President Dick Cheney had just sat down for a meeting when his assistant told him to turn on his television because a plane had struck the NorthTower of the World Trade Center. The Vice President was wondering "How the hell could a plane hit the World Trade Center" when he saw the second aircraft strike the South Tower. Elsewhere in the White House, a series of 9:00 meetings was about to begin. In the absence of information that the crash was anything other than an accident, the White House staff monitored the news as they went ahead with their regular schedules. <sep>What was the White House response to the initial reports of the crash?<sep>National Militia Command Center

Answer: No

Question: Even after Bin Laden's departure from the area, CIA officers hoped he might return, seeing the camp as a magnet that could draw him for as long as it was still set up. The military maintained readiness for another strike opportunity. On March 7, 1999, Clarke called a UAE official to express his concerns about possible associations between Emirati officials and Bin Laden. Clarke later wrote in a memorandum of this conversation that the call had been approved at an interagency meeting and cleared with the CIA. When the former Bin Laden unit chief found out about Clarke's call, he questioned CIA officials, who denied having given such a clearance. Imagery confirmed that less than a week after Clarke's phone call the camp was hurriedly dismantled, and the site was deserted. CIA officers, including Deputy Director for Operations Pavitt, were irate." Mike" thought the dismantling of the camp erased a possible site for targeting Bin Laden. The United Arab Emirates was becoming both a valued counterterrorism ally of the United States and a persistent counterterrorism problem. From 1999 through early 2001, the United States, and President Clinton personally, pressed the UAE, one of the Taliban's only travel and financial outlets to the outside world, to break off its ties and enforce sanctions, especially those relating to flights to and from Afghanistan. These efforts achieved little before 9/11. In July 1999, UAE Minister of State for Foreign Affairs Hamdan bin Zayid threatened to break relations with the Taliban over Bin Laden. The Taliban did not take him seriously, however. Bin Zayid later told an American diplomat that the UAE valued its relations with the Taliban because the Afghan radicals offered a counterbalance to "Iranian dangers" in the region, but he also noted that the UAE did not want to upset the United States. <sep>When and why did the UAE Minister of State for Foreign Affairs Hamdan bin Zayid threaten to break relations with the Taliban over Bin Laden?<sep>March 7, 1999
