Divergent Plate Boundary

Mantle

The earth's crust is broken into tectonic plates that move constantly.

Transform Plate Boundary

Convergent and Divergent Plate Boundary

Continental Crust and Oceanic Crust

Oceanic crust is denser and heavier than continental crust

The Mid-Atlantic Ridge

Convection Currents

Subduction

Hot air rises, cold air sinks

Slab-Pull Force

The Pacific Plate, despite being the largest and heaviest plates, moves the fastest (10-11cm per year)

Seafloor Spreading

Convection currents in the mantle drive plate movements.

The thickness and density of oceanic and continental crust differ significantly.

The three types of plate boundaries result in different landforms and phenomena.

The Pacific Plate is one of the fastest-moving tectonic plates.

The core’s high temperature causes mantle convection, which moves the overlying tectonic plates.

Convection Currents and Slab-Pull Force

The process of subduction creates deep oceanic trenches.

Magnetic Striping

The age of rocks near a mid-ocean ridge is younger than those farther away.

Age of Rocks

Japan experiences frequent earthquakes because it sits on multiple plate boundaries.
