Question

questions 1 through 3 refer to the following. 3 mark for review at which of the following sites does seafloor spreading result in rifts and possible volcanoes? a a b b c c d d

Explanation:

Seafloor spreading occurs at divergent plate boundaries. In the diagram, site A shows the plates moving apart (divergent boundary). At divergent boundaries, magma rises from the mantle to fill the gap created by the spreading plates. This can result in rifts (as the plates pull apart) and volcanic activity (as magma erupts onto the seafloor).

Answer:

A. A
