WGU C165 Questions and Answers Rated A Speed ✔✔how fast an object is moving Which of the following statements BEST describes the locations of volcanoes? ✔✔Most volcanoes are located along the edges of some continents or in chains off the coast of continents. Some plate boundaries have ✔✔active volcanoes but some don't, and almost all volcanoes are at boundaries. The typical speed of a plate is ✔✔a few centimeters per year. An atmospheric instability causes a column of air to rotate. ✔✔Tornado A moist mass of air over warm ocean water condenses as it rises, forming a massive spinning storm. ✔✔hurricane This type of storm is common at cold fronts and often produces lightning. ✔✔Thunderstorms This is the most violent storm on Earth. ✔✔tornadoes. A hurricane has an ✔✔eye in the center that is very calm. Lightning is an ✔✔electric glow that can be seen during a storm. Differences in temperature within Earth and within the plates result in ✔✔processes that move plates. A low-lying cloud of small water droplets that reduces visibility to less than 1 km (0.62 mi) is called ✔✔fog Which radiation can greenhouse gases absorb that nitrogen and oxygen cannot? ✔✔Greenhouse gases can absorb infrared radiation, which nitrogen and oxygen cannot. Which of the following are considered greenhouse gases? ✔✔carbon dioxide and methane Which kind of plate boundary produced the Himalayas? ✔✔Two plates pushed into each other to push the land upward and generate a mountain range. Greenhouse gases in Earth's atmosphere ✔✔absorb infrared radiation emitted by the ground. After absorbing incoming solar radiation, Earth emits mostly __________, which is the radiation associated with heat. ✔✔infrared radiation The greenhouse effect __________. ✔✔helps keep Earth's surface sufficiently warm for life to exist The greenhouse effect occurs because greenhouse gases __________. ✔✔absorb infrared radiation emitted by the surface If more water vapor was present in Earth's atmosphere, what would happen to Earth's temperature? ✔✔The temperature would increase. The most abundant greenhouse gas in volcanic eruptions is __________. ✔✔water vapor Solar radiation __________. ✔✔has been increasing over the past several billion years Which of the following is a natural process that adds carbon dioxide to the atmosphere? ✔✔respiration Plants remove carbon dioxide from the atmosphere and cutting down forests ✔✔increases the rate of global warming. If the mass of the box increases, but the force remains the same, the box's acceleration will ✔✔decrease Why does San Francisco have earthquakes? ✔✔San Francisco lies along the boundary between the North American plate and the Pacific plate. At this location, they are grinding past each other, occasionally slipping suddenly along a transform fault. If the mass of an object increases, ✔✔a given force will produce less acceleration. When force increases ✔✔acceleration also increases, according to Newton's second law.
