Crust is destroyed at the same time it is created

New crust is underwater where it sinks

New crust breaks more easily than old crust

continental landmasses were too big to move slowly over Earth's surface

Wegener couldn't explain why or how the continents  moved

magnetic and sonar data proved that Wegener's hypothesis was incorrect

mantle convection currents weren't in motion at that time

The mirror image show they formed under the same magnetism

They are nearest the trench

They show magnetism and the white bands have no magnetism

They are still cooling because they were formed most recently

it creates rift crack and valley, water enters forming a lake/sea, eventually becoming an ocean

Earth's internal heating

cooler, denser crust sinks (is pulled) into the mantle along a trench

when edges become denser and gravity pulls them downward and away from one another

currents just beneath Earth's crust flow very slowly, causing movement in the plates above them
