Answer 2

Modern theories of plate tectonics describe the relative movement of continents.

Explanation:

These ideas explain how lithospheric plates, which include the visible continents, travel over the asthenosphere (the molten, ductile top section of the Earth's mantle). In a historical sense, the now-discredited theories for continental drift were based on out-of-date ideas about the structure of the Earth.

Continental drift explanations that lasted long into the twentieth century made the unlikely geophysical claim that continents migrated through and over an underlying oceanic crust in the same way as ice floats and drifts across water. Multiple lines of evidence eventually led to the replacement of continental drift hypothesis by current tectonic theory.
