Plate Boundaries

Sliding Boundaries Convergent Boundaries Divergent Boundaries

Sliding Boundaries Plates sliding sideways against each other. Plates rubbing together form earthquakes. Example: San Andreas Fault in California.

Convergent Boundaries

Plates pushing together. Plates pushing or colliding together form

earthquake and volcanoes.

Convergent Boundaries Plates push together to form mountains. Example: Rocky and Himalayas Mountains. When continental and oceanic plates collide the

thinner plate slides under the other plate. This is called subduction.

Divergent Boundaries Plates pulling apart. Plates separate to form volcanoes and minor

earthquakes. Example: Mid Atlantic ridge

Mountain Building New mountains form when plates pull apart magma

push out from below and the lava cools and turns to rock.

Mountain Building

When plates push together, one plate is pushed beneath the other one, and this creates mountains.

Fault Block Mountains

Form when masses of rock move upor down along a fault.

Folded Mountains

Form when two tectonic plates collide.

Dome Mountains

Form when the surface is lifted up by magma, forming a bulge.
