What is the difference between a fracture zone and transform fault?
a) A transform fault is perpendicular to the mid-ocean ridge, but a fracture zone is not
b) A transform fault is a crack in the crust, but a fracture zone is a hole in the crust that extends into the mantle
c) A transform fault runs along a zone of weakness in the crust while a fracture zone runs along a zone of strong, erosion-resistant rock
d) Transform faults run between offsets in a mid-ocean ridge while fracture zones extend beyond the offsets
e) Transform faults are stationary while fracture zones have strike-slip motion
Question 2
What would happen to longshore transport along the coast if rivers on the coast were dammed, trapping sand behind the dams?
a) The longshore current would become less.
b) The longshore transport would become less.
c) There would be no effect because sand would get through with water released from the dams.
d) Sand from beaches upstream in the longshore current would replace the sand missing from the rivers.
e) Sand in the longshore current would be replaced by finer grained sediments from the rivers.
