What Do You Mean By Plate Boundary?

What do you mean by plate boundary?

 

PLATE BOUNDARY can be charaterized by:

1. Divergent boundaries -- where new crust is generated as the plates pull away from each other.

2. Convergent boundaries -- where crust is destroyed as one plate dives under another.

3. Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other.

4. Plate boundary zones -- broad belts in which boundaries are not well defined and the effects of plate interaction are unclear.
