List three evidences Wegener used to support his theory that all the continents used to be joined together? 200 pts. What kind of plate boundary causes sea floor spreading? 300 pts. List three evidences that support Hess’s Theory of Sea Floor Spreading. 400 pts. What volcanic mountain range is forming in South America as a result of the South American plate colliding with an oceanic plate? 500 pts. Pangaea 100 pts. Landforms, Fossils, Climate, Glacial scarring, and/or Rock types. 200 pts. Divergent Boundary 300 pts. age of ocean floor, record of magnetic reversals, and mid ocean ridges. 400 pts. The Andes Mountains 500 pts. • Why are there convection currents in the mantle? 100 pts. • List the three types of Plate Boundaries and draw arrows to show the direction the plates are moving. 200 pts. • What causes the plates to move around? 300 pts. • What is it called when one plate moves under another plate? 400 pts. • What are the two types of crust? 500 pts. Heat from the core heats and expands lower mantle, making it less dense so it floats to the top, where it cools and contracts, making it sink. 100 pts. Convergent, Divergent, and Transform 200 pts. Convection currents 300 pts. subduction 400 pts. Continental and oceanic. 500 pts. • Draw an anticline. 100 pts. • Draw a reverse fault. 200 pts. • _______________ is the type of stress in which rock is squeezed. 300 pts. • What kind of stress causes a normal fault? 400 pts. • What is the difference between a fold and a fault? 500 pts. 100 pts. 200 pts. compression 300 pts. Tension 400 pts. Folds occur when the rock BENDS, Faults occur when the rock BREAKS. 500 pts. • What are the three types of volcanoes? 100 pts. • List three places volcanoes can form. 200 pts. • What causes Earthquakes? 300 pts. • What type of plate boundary causes earthquakes along California’s San Andreas Fault? 400 pts. • What three variables can be changed to allow the rock in the Earth’s Mantle to melt? 500 pts. Shield, cinder cone, and composite 100 pts. Divergent boundaries, convergent boundaries, and hot spots. 200 pts.
