Plate Tectonics Review

Identify the three types of plate boundaries. Using the word list fill in the blanks on the picture with the word that matches the picture. Convergent Divergent Transform Divergent Convergent Transform Which layer of the Earth do convection currents occur? crust inner core mantle What causes the crustal plates to move? Earthquakes Volcanoes Convection Currents Which of the following is not a type of crust? continental oceanic mountainic What is the name for process that causes one plate to sink under another at a convergent plate boundary? Subduction Island Arc Rift Read the following passage about tectonic plate boundaries and fill in the blanks as you go. The border between two tectonic plates is called a boundary. All the tectonic plates are constantly moving — very slowly — around the planet, but in many different directions. Some are moving toward each other, some are moving apart, and some are sliding past each other. Because of these differences, tectonic plate boundaries are grouped into three main types.A convergent boundary occurs where two plates are pushing toward each other.A divergent boundary marks two plates that are moving apart from each other.A transform boundary occurs where two plates slide past each other. Sea-floor spreading, middle ocean ridges, and rift valleys all form along which type of plate boundary? Divergent Convergent Transform Mountains, subduction, and trenches all form along which type of plate boundary? Divergent Convergent Transform What is the image above demonstrating? Convergent boundary Transform boundary Seafloor spreading Ridge push On the image above, where is the OLDEST crust found? 1 2 3 Zone of magma generation Thich of the following tectonic plates is the most dense? Oceanic Continental Both Neither What is the image above showing? Divergent boundary Mantle convection Subduction and convergent boundary Transform boundary Convergent Boundary Plates moving together Subduction Trenches created Example: Appalachian mountains Creates chain of volcanoes Divergent Boundary Plates moving apart Seafloor spreading Rift valley created Example: East African Rift Transform Boundary Plates sliding past each other Earthquakes Long faults Example: San Andreas Fault
