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.
