Plate Boundaries & Land forms Quiz

Use the drop down word bank to complete the passage below. The area 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 towards each other, some are moving apart, and some are sliding past each other. Because of these differences, tectonic plate boundaries are grouped into threemain types.A convergent boundary occurs where two plates are pushing toward each other.A divergent boundary occurs where two plates are moving apart from each other.A transform boundary occurs where two plates slide past each other. For each picture below, identify the plate boundary by clicking on the blinking dot and typing in the name. (*Use all lower case letters. Spelling will count against you, so use your resources!) divergent convergent transform What is the name for the proccess that causes one plate to sink under another at a convergent plate boundary? subduction island arc rift Match each land form with the appropriate definition. Sea Floor Spreading The process by which magma rises from the ocean floor at a divergent boundary and cools to form new crust (pushing older crust further away from the source). Ring of Fire A string of volcanoes and sites of seismic activity (earthquakes) around the edges of the Pacific plate. Mid-Ocean Ridge A land form created on the ocean floor that occurs when convection currents rise in the mantle beneath oceanic crust and spew up magma at a divergent boundary. Rift Valley A land form created on Earth's surface that occurs when 2 continental plates move away from each other at a divergent boundary. Use the drop down word bank to complete the passage below. Continental plates are less dense. Oceanic plates are more dense. Use the drop down word bank to complete the passage below. Mountains can form when 2 continental plates collide at a convergent boundary.Volcanoes can form when continental and oceanic plates create subduction zones at convergent boundaries.Deep ocean trenches can form when 2 oceanic plates create subduction zones at convergent boundaries. An earthquake can occur when 2 plates slide past each other creating friction and building energy until it is released. True False Earthquakes can occur at any boundary, but occur most often at a divergent boundary. True False Sort the different types of Convergent and Divergent boundaries into the correct category.
