Answer An Island Arc Home What is an undersea mountain range formed at a divergent boundary? Answer Mid-ocean Ridge Home What kind of boundary would from a mountain range? Answer Convergent Home Boundary where 2 plates are moving away from each other Answer Divergent Home Where are most divergent boundaries found? Answer On the ocean floor Home The San Andreas Fault is an example of this type of boundary Answer Transform . Home What are 2 types of surface waves? Answer Love and Rayleigh Home What is an area where no direct seismic waves can Be detected? Answer Shadow Zone Home What scale do we use to describe the intensity of an earthquake? Answer Modified Mercalli Home What is it called when rocks on each side of a fault suddenly return to their undeformed shape? Answer Elastic Rebound Home What are the most damaging seismic waves? Answer Surface Waves Home When this molten rock solidifies beneath Earth’s surface, intrusive igneous rock forms Answer Magma Home Magma that erupts onto Earth’s surface is called what? Answer Lava Home Volcanically active area of Earth’s surface commonly far away from a tectonic plate Answer Hot Spot Home This forms in the ocean where one plate is subducted Answer Trench Home Magma formed from an underwater volcano is called what? Answer Pillow Lava Home What is the supercontinent that formed 300 million years ago? Answer Pangea Home What scales do we use to measure the magnitude of an earthquake? Answer Richter and Moment Magnitude Home The point on Earth’s surface directly above the focus of an earthquake Answer Epicenter Home A large pluton that can cover an area as big as 100 km2 is a _________ Answer Batholith Home Devils Tower was caused by the cooling of magma within Earth’s crust until erosion revealed it. What is this structure called? Answer A Pluton Home
