Plate Tectonics MrB

What happens in sea-floor spreading?

Earth's inner core consists of

The process by which the ocean floor sinks beneath a deep-ocean trench & back into the mantle 

Matching fossils & rock types on continents that are separated by ocean today supports the idea

Relating cause & effect: What causes the convection currents labeled A? (label A and B)

Scientists think all present-day continents were once joined in a single super-continent called

How does fossil evidence support Wegener's hypotheses of continental drift?

Most of the world's folded mountains formed as a result of

A boundary where two plates push together is called

Once magma reaches the surface it is called
