Plate BoundariesPlate Boundaries
• Plate boundaries are found at the edge of the lithospheric plates and are of three types, convergent, divergent and conservative
Plate BoundariesPlate Boundaries
• Convergent Plates: – When plates move toward each other

• Subductions Zones - created where plates collide
