Wegener's hypothesis of continental drift was finally confirmed by

evidence supporting the idea of sea-floor spreading.

Tectonic plates can include

both oceanic and continental crust

What occurs at a transform boundary?

Two plates slide past each other.

There are two types of divergent boundaries:

mid-ocean ridges and rift valleys.

To assign ages to sea-floor rocks, scientists used

the geomagnetic reversal time scale.
