Which evidence provides support for the motion of Earth's tectonic plates being predictable?

The mantle plume is slowly moving east

Performing field surveys will help scientists study Earth's crust.

Older rocks are found on continents vs. the ocean floor.

The oceanic plate is moving west

Drilling bore holes will help scientists study Earth's crust.

Which statement describes the boundary where two oceanic plates collide?
