You may be wondering, how can a glacier get so big? Why does it move? These are both good questions. In the winter months, precipitation falls as snow. This solid form of water builds up on the ground as long as the temperatures stay cold enough. As the temperature rises, the snow starts to melt. The frozen water changes state back into a liquid state. Nearer the poles, summer does not last very long. If the summer is long enough and warm enough, all the snow may melt. This is what typically happens now. The earth was a little cooler 12,000 years ago. As a result, during the summer months, that amount of snow did not melt. It may have only been an inch or so of snow that melted. The following winter, snow fell on top of this left-over snow. This next winters snowfall had a head start. Year after year, the snow that did not melt became thicker and thicker. Inch by inch the snow started to build up. Over many years, layer upon layer of snow compacted and turned to ice.

Question: "How do glaciers form?"

Response: "During winter, precipitation falls as snow, and then this solid form of water builds up on the ground as long as the temperatures stay cold enough"

A: yes

Electric charge is a physical property. It occurs between particles or objects. It causes them to attract or repel each other. They do not even have to touch. This is unlike the typical push or pull you may be familiar with. All electric charge is based on the protons and electrons in atoms. A proton has a positive electric charge. An electron has a negative electric charge. Forces on Charged Objects Most atoms are balanced electrically. They have the same number of positive and negative charges. Therefore, the number of protons equals the number of electrons. Neutrons do not matter as they have no charge. When an object loses some electrons, it becomes positively charged. There are now more protons than electrons inside the atom. The lost electrons may remain free. Or, they may attach to another object. The new object now has more electrons than protons. It then becomes negatively charged.

Question: "If a particle loses some of its protons, what is the particle's charge?"

Response: "It is negativity charged"

A: yes

While Nashiri was in Afghanistan, Nibras and Khamri saw their chance. They piloted the explosives-laden boat alongside the USS Cole, made friendly gestures to crew members, and detonated the bomb. Quso did not arrive at the apartment in time to film the attack. Back in Afghanistan, Bin Laden anticipated U.S. military retaliation. He ordered the evacuation of al Qaeda's Kandahar airport compound and fled- first to the desert area near Kabul, then to Khowst and Jalalabad, and eventually back to Kandahar. In Kandahar, he rotated between five to six residences, spending one night at each residence. In addition, he sent his senior advisor, Mohammed Atef, to a different part of Kandahar and his deputy, Ayman al Zawahiri, to Kabul so that all three could not be killed in one attack. There was no American strike. In February 2001, a source reported that an individual whom he identified as the big instructor (probably a reference to Bin Laden) complained frequently that the United States had not yet attacked. According to the source, Bin Laden wanted the United States to attack, and if it did not he would launch something bigger. The attack on the USS Cole galvanized al Qaeda's recruitment efforts. Following the attack, Bin Laden instructed the media committee, then headed by Khalid Sheikh Mohammed, to produce a propaganda video that included a reenactment of the attack along with images of the al Qaeda training camps and training methods; it also highlighted Muslim suffering in Palestine, Kashmir, Indonesia, and Chechnya. Al Qaeda's image was very important to Bin Laden, and the video was widely disseminated. Portions were aired on Al Jazeera, CNN, and other television outlets. It was also disseminated among many young men in Saudi Arabia and Yemen, and caused many extremists to travel to Afghanistan for training and jihad. Al Qaeda members considered the video an effective tool in their struggle for preeminence among other Islamist and jihadist movements.

Question: "What actions did Bin Laden take fearing retaliation?"

Response: "He ordered the evacuation of al Qaeda's Kandahar airport compound and fled- first to the desert area near Kabul, then to Khowst and Jalalabad, and eventually back to Kandahar. In Kandahar, he rotated between five to six residences, spending one night at each residence.
