Types of Plate Boundaries

Seafloor spreading is a theory proposing that new ocean crust forms at mid-ocean ridges and is destroyed at trenches.
Plates are large slabs of Earth's crust and upper mantle.
Convection currents in the mantle drive plate movement.
Magma rises at mid-ocean ridges, creating new seafloor.
Plates collide at convergent boundaries, where one plate may subduct (slide under).
Subduction results in volcanic activity and deep trenches.
Divergent boundaries are where plates pull apart, forming rift valleys or mid-ocean ridges.
Transform boundaries are where plates slide past each other, generating earthquakes.

Divergent Boundaries

Plates move apart, creating gaps.
Magma rises to fill the gap, forming new seafloor.
Mid-ocean ridges are examples of divergent boundaries.
Found primarily under the oceans, creating new seafloor.
Earthquakes and volcanic activity frequently accompany divergent boundaries.
Iceland is a unique location with a divergent boundary on land.

Convergent Boundaries

Plates collide.
One plate may subduct (slide under) another, leading to trenches.
Subduction causes volcanic activity.
Oceanic-oceanic collisions form volcanic island arcs.
Oceanic-continental collisions result in volcanic mountain ranges.
Continental-continental collisions create the highest mountain ranges.

Transform Boundaries

Plates slide past one another horizontally.
This movement generates tremendous stress and strain.
Earthquakes are a common feature of transform boundaries.
The San Andreas Fault is an example of a transform boundary.
