  1. 4. was a supercontinent that existed during the late Paleozoic and early Mesozoic eras.
  2. 5. a process in plate tectonics that occurs when one tectonic plate slides beneath another, usually at a convergent plate boundary
  3. 6. is the wearing down of rocks, soils, minerals, wood, and artificial materials by the action of water, atmospheric gases, sunlight, and biological organisms
  4. 7. Plates crash together, causing earthquakes and sometimes the formation of volcanoes.
  5. 9. the edges where two tectonic plates meet and move relative to each other
  6. 10. Plates slide past each other, causing shallow earthquakes and sometimes the creation of fault valleys or undersea canyons
Down
  1. 1. the number of major tectonic plates
  2. 2. a sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earth's crust or volcanic action.
  3. 3. Plates move apart, causing volcanic activity and shallow earthquakes
  4. 8. is a geological process in which earthen materials (ie, soil, rocks, sediments) are worn away and transported over time by natural forces
