Wilson Cycle Tectonics

Which statement describes John Tuzo Wilson’s contribution to the theory of plate tectonics?

• He proposed that plates carry parts of the seafloor.

• He theorized that pieces of Earth move for a limited time.

• He suggested that the asthenosphere is broken into segments.

• He observed seafloor cracks similar to existing cracks in the continents.

Which statement describes the process of subduction?

• Convection currents pull a plate into the mantle.

• One plate slides beneath another due to gravitational pull.

• Materials are transferred within Earth’s interior by density.

• Heat cycles in the mantle cause plates to constantly move.
