Answer the following question given this paragraph: In some places, the oceanic crust comes up to a continent. The moving crust pushes that continent away from the ridge axis as well. If the moving oceanic crust reaches a deep sea trench, the crust sinks into the mantle. The creation and destruction of oceanic crust is the reason that continents move. Seafloor spreading is the mechanism that Wegener was looking for!. Q: What happens to the crust if the moving oceanic crust reaches a deep sea trench? Choices: - ocean volcano - it cleaves - forms a continent - sinks into mantle A:
sinks into mantle

Answer the following question given this paragraph: Electromagnetism is magnetism produced by an electric current. Current flowing through a wire creates a magnetic field that surrounds the wire in concentric circles. Q: What is magnetism produced by an electrical current? Choices: - strong magnetism - hydromagnetism - exomagnetism - electromagnetism A:
electromagnetism

Answer the following question given this paragraph: Fats may be either saturated or unsaturated. A saturated fat is a fat that consists of triglycerides whose carbon chains consist entirely of carbon-carbon single bonds. Therefore, the carbon chains are saturated with the maximum number of hydrogen atoms possible. An unsaturated fat is a fat that consists of triglycerides whose carbon chains contain one or more carbon-carbon double bonds . A fat with one double bond is called monounsaturated, while a fat with multiple double bonds is called polyunsaturated (see Figure below ). Q: What are the two types of fats? Choices: - thick and thin - full and empty - liquid and solid - saturated and unsaturated A:
saturated and unsaturated
