  c) Hotspots surround the Pacific Plate
  d) The Ring of Fire is folklore, and the rate of earthquakes is the same everywhere

Question 2

At mid-ocean ridges, seamounts and pillow lavas (basalts) are found. What is the difference between these structures?
 
  a) Seamounts are found at convergent boundaries while pillow lavas are found at divergent boundaries.
  b) Pillow basalts form when hot lava from the sea floor is cooled quickly by cold seawater, creating smooth, rounded lobes. A seamount is an underwater volcano.
  c) Seamounts are flat topped while pillow lavas are rounded.
  d) Pillow lavas are formed at continental arcs while seamounts are formed at island arcs.
