Continental slope Large flat area of the ocean floor is called a _____ plain What rock continental plates are made of. granite What rock ocean plates are made of. basalt What is the other name of a plate ? lithosphere What the plates slide on asthenosphere How many major plates are there ? 10-12 The thickest layer of the earth’s interior mantle Thinnest layer of the earth crust Which layer is liquid Outer core List the 4 layers of Earth’s interior in order Crust, mantle, outer core, & inner core How did we figure out what the inside of the Earth was made of ? earthquakes Plate boundary that creates folded mountains. Convergent continent and continent Type of plate boundary that creates a mid-ocean ridge and rift zone. divergent Type of plate boundary that only creates earthquakes. Transform fault What are the 2 types of plate boundaries that create trenches Convergent ocean – ocean and convergent ocean - continent How many plate boundaries create volcanoes ? 3 What is the name of the Island Arc volcanic mountains created Plate Interactions Japanocean-ocean at a convergent boundary. What is an example.
