Which geologic formations can occur at a convergent plate boundary? Ocean + Continental Crust: ____________________________ Continental + Continental Crust: ____________________________ 9. Where do earthquakes occur (what type of boundaries)? 6.E.2.2 Maps 10. The boundary at point A is the same as the B boundary at point C. What type of boundary is at A and C? _______________________ -Explain what geologic formations will happen at A? C A -What geologic formations will happen at C? -Why will these A and C have different geologic activity even though they are the same type of boundary? 11. Where are earthquakes and volcanoes most often located? 12. Why do you think there are so few earthquakes in North Carolina? 13. What will happen when all the inner core heat energy is lost? (Think about convection currents) 14. Based on this map, where would you expect to find a plate boundary (Area A, B, C or D) and WHY? 15.
