The point where two or more plates meet is known as a plate boundary. It is at these locations where earthquakes, volcanoes and fold mountain form. There are four main types of plate boundary. These are constructive, destructive, conservative and collision margins.
Constructive / Tensional (divergent ) Plate Boundary
A constructive plate margin
A constructive plate boundary occurs when two plates move away from each other.
Landforms: Ocean ridge and volcanic islands
Destructive plate boundary (subduction zones)
A destructive plate margin
A destructive plate boundary occurs when an oceanic plate is forced under (or subducts) a continental plate.
Landforms: Fold Mountains and Oceanic trenches
Example: Pacific Plate and the Eurasian Plate
Conservative (transform faults) plate boundary
A conservative plate margin
A conservative plate boundary occurs when two plates slide past each other.
Example: North American Plate and the Pacific Plate
Collision plate boundaries
Collision plate boundaries occur when two continental plates move towards each other.
Landforms: Fold Mountains
Example: Australian and the Eurasian Plate
