What causes foliation in a metamorphic rock?
Regional SpecificsFoliation forms when pressure squeezes the flat or elongate minerals within a rock so they become aligned. These rocks develop a platy or sheet-like structure that reflects the direction that pressure was applied. What causes foliation to occur? Foliation is caused by the re-alignment of minerals when they are subjected to high pressure and temperature.

What are typical rates of seafloor spreading?
Regional SpecificsThese age data also allow the rate of seafloor spreading to be determined, and they show that rates vary from about 0.1 cm (0.04 inch) per year to 17 cm (6.7 inches) per year. Does seafloor spreading occur at the same rate? Seafloor spreading is mainly the result of convection currents dragging the ocean plate

What type of earthquake generates a tsunami?
Regional SpecificsMost tsunamis are generated by earthquakes with magnitudes over 7.0 that occur under or very near the ocean and less than 100 kilometers (62 miles) below Earth’s surface (earthquakes deeper than this are unlikely to displace the ocean floor). What type of earthquake produces tsunamis? The earthquake must be a shallow marine event that displaces
