CONSTRUCTIVE PLATE BOUNDARY:
A constructive plate boundary, also known as a divergent boundary is when plates are moving apart. Magma rises through the gap into the earth’s crust and new land is formed. An example of a constructive boundary is the Mid-Atlantic Ridge.

DESTRUCTIVE PLATE BOUNDARY: A destructive boundary, also known as a convergent boundary is when the plates are converging and the plate boundary is destroyed. When an oceanic plate moves towards a continental plate, the denser oceanic plate sinks below the continental plate. An example of a destructive boundary is the subduction zone between the Nazca and South American Plate. CONSERVATIVE PLATE BOUNDARY: A conservative plate boundary, also known as a transform plate margin occurs when two plates move horizontally alongside each other. The plates can either move in opposite directions or in the same directions but at different speeds. An example of a conservative plate margin is the San Andreas Fault in California. |
