Description/Features of Plate Boundary
Examples
A rift area occurs where plate movement
creates a crack in Earth’s crust. Lava flows
through to fill the crack, creating new crust.
Volcanoes and earthquakes occur here.
The Mid-Atlantic
Ridge
Jerky motion is felt as the plates slide past
each other causing earthquakes
The San Andreas
Fault causes
earthquakes in CA
Sliding Boundary
Plates slide past
each other in
opposite
directions.

Collision
Plates are moving When continental plates collide, crustal

mountains.
The Himalayas
were created when
the Indian Plate
collided with the
Eurasian Plate.
Subduction:
Ocean-Ocean
One ocean plate
dips beneath the
other ocean plate.
Deep trenches are formed at the boundary
site. Volcanoes and under-water earthquakes
occur here.
The Marianas
Trench
The ocean plate
dips beneath the
continental plate.
Deep trenches occur at the collision site.
These areas are also prone to earthquakes and
volcanoes.

North American
