Flowing water causes sediment to move. Flowing water can erode both rocks and soil. You have already learned that materials can dissolve in water. With enough time, even rocks can be dissolved by water. This process happens really slowly. It may take over a million years to dissolve a rock. It doesnt matter how big the rock is. With enough time, flowing water can dissolve it. Moving water also has the ability to move small pieces of rock and soil. How can water move a rock? Doesnt it need energy? Of course, water gets its energy because it is moving. Moving water has kinetic energy. Things that have more energy can do more work. When water stops moving it will have no energy. It will no longer be able to move the rock and soil. When this happens the rock and soil will settle to the bottom of the calm water. Scientists call this process deposition.

Question: "Would deposition of or the moving of a particular rock take more energy?"

Response: "Deposition of rock"

- no

What a time of it Dawson's Landing was having! All its life it had been asleep, but now it hardly got a chance for a nod, so swiftly did big events and crashing surprises come along in one another's wake: Friday morning, first glimpse of Real Nobility, also grand reception at Aunt Patsy Cooper's, also great robber raid; Friday evening, dramatic kicking of the heir of the chief citizen in presence of four hundred people; Saturday morning, emergence as practicing lawyer of the long-submerged Pudd'nhead Wilson; Saturday night, duel between chief citizen and titled stranger. The people took more pride in the duel than in all the other events put together, perhaps. It was a glory to their town to have such a thing happen there. In their eyes the principals had reached the summit of human honor. Everybody paid homage to their names; their praises were in all mouths. Even the duelists' subordinates came in for a handsome share of the public approbation: wherefore Pudd'nhead Wilson was suddenly become a man of consequence. When asked to run for the mayoralty Saturday night, he was risking defeat, but Sunday morning found him a made man and his success assured.

Question: "What had Pudd'nhead Wilson assured his success in?"

Response: "The grand reception at Aunt Patsy Cooper's"

Early in chapter 5 we introduced, along with Khalid Sheikh Mohammed, two other men who became operational coordinators for al Qaeda: Khallad and Nashiri. As we explained, both were involved during 1998 and 1999 in preparing to attack a ship off the coast of Yemen with a boatload of explosives. They had originally targeted a commercial vessel, specifically an oil tanker, but Bin Laden urged them to look for a U.S.warship instead. In January 2000, their team had attempted to attack a warship in the port of Aden, but the attempt failed when the suicide boat sank. More than nine months later, on October 12,2000, al Qaeda operatives in a small boat laden with explosives attacked a U.S. Navy destroyer, the USS Cole. The blast ripped a hole in the side of the Cole, killing 17 members of the ship's crew and wounding at least 40. The plot, we now know, was a full-fledged al Qaeda operation, supervised directly by Bin Laden. He chose the target and location of the attack, selected the suicide operatives, and provided the money needed to purchase explosives and equipment. Nashiri was the field commander and managed the operation in Yemen. Khallad helped in Yemen until he was arrested in a case of mistaken identity and freed with Bin Laden's help, as we also mentioned earlier. Local al Qaeda coordinators included Jamal al Badawi and Fahd al Quso, who was supposed to film the attack from a nearby apartment. The two suicide operatives chosen were Hassan al Khamri and Ibrahim al Thawar, also known as Nibras. Nibras and Quso delivered money to Khallad in Bangkok during Khallad's January 2000 trip to Kuala Lumpur and Bangkok. In September 2000, Bin Laden reportedly told Nashiri that he wanted to replace Khamri and Nibras. Nashiri was angry and disagreed, telling others he would go to Afghanistan and explain to Bin Laden that the new operatives were already trained and ready to conduct the attack. Prior to departing, Nashiri gave Nibras and Khamri instructions to execute the attack on the next U.S.warship that entered the port of Aden.

Question: "Who provided the funds for the attack on the USS Cole?"

Response: "Bin Laden"
