Answer 14

transform boundary

Question 15

pulling plates

Answer 15

convergent boundary

Question 16

seprating plates

Answer 16

divergent boundary

Question 17

sea-floor spreading landforms

Answer 17

◍ rift valleys

Divergent/constructive plate boundaries

Answer 18

◍ sea floor spreading
◍ Mid-Atlantic ridge
◍ \two plates pull apart
◍ plates move in opposite directions
◍ Rising magma solidifies making new land and rift valleys
