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. After reading the above, is "It moves horizontally" the correct answer to the question "Which direction does the mantle move?"?

Answer:
yes

Question:
The dermis is the inner layer of skin. The dermis has blood vessels and nerve endings. The nerve endings explain why your skin is sensitive. You can sense pain, pressure, and temperature. You cut your finger and it starts to bleed. What has happened? If your skin bleeds, it means you have cut the dermis layer and damaged blood vessels. The cut really hurts. It hurts because of the nerve endings in this skin layer. The dermis also contains hair follicles and two types of glands. Hair follicles are structures where hairs originate. Each hair grows out of a follicle. Hair passes up through the epidermis. It then extends above the skin surface. Oil glands produce an oily substance. The oil is secreted into hair follicles. After reading the above, is "The dermis contains hair follicles" the correct answer to the question "What is the relationship of hair to the dermis?"?

Answer:
yes

Question:
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. After reading the above, is "As the temperature rose, the snow started to melt" the correct answer to the question "How does the snow turn into ice?"?

Answer:
no

Question:
(CNN) -- A Christian evangelical group said Thursday that a Bible school -- backed by American evangelist Franklin Graham -- was destroyed in the latest bombing raid to hit South Kordofan, an oil-rich Sudanese province that borders the newly created independent country of South Sudan. At least eight bombs were dropped in the area Wednesday during the school's first day of classes, according to a statement by Samaritan's Purse, Graham's Christian humanitarian group, which supports the school. Two bombs landed inside the compound -- located in the region's Nuba Mountains -- destroying two Heiban Bible College buildings and igniting grass fires across the area, the group said in a statement No injuries were reported. "It was a miracle that no one was injured," the statement added. Graham, who has called on the international community to take out Sudan's air assets and establish a no-fly zone in the region, said in a statement Thursday that he blamed Sudan's air force for the strike. At least four churches have been destroyed since August, the group said. "We are deeply concerned for the welfare and lives of the people of South Kordofan and we condemn the bombing of churches and Christian facilities," added Graham, son of the famed Rev. Billy Graham. More than 78,000 people have fled South Kordofan and Blue Nile states since August of last year after an armed rebellion took root, the United Nations reported. The Sudanese government is thought to have responded to the rebellion by conducting sustained air raids with the use of Russian-made Antonov bombers, which have raised concerns over civilian casualties. Decades of civil war between the north and south, costing as many as 2 million lives, formally ended with a U.S.-brokered peace treaty in 2005. After reading the above, is "North sudan" the correct answer to the question "Where was the location of the bombing?"?

Answer:
no
