DIVERGENT PLATE BOUNDARY: -Plates move away from the mid-ocean ridge due to the direction the convection currents in the asthenosphere are traveling.-Sea-floor spreading happens here.
THE RED SEA:
- This is an example of a Divergent Plate Boundary.
-The African and Arabian plates are moving in opposite directions away from the mid-ocean ridge that runs through the center of this sea.
-The Red Sea gets slightly larger each year due to the sea-floor spreading that happens here.

CONVERGENT PLATE BOUNDARIES
1. Oceanic-Oceanic2. Continental-Continental3. Oceanic-Continental
Questions to think about:-What happens at each of these types of convergent boundaries?-What features will you find on the Earth's surface at each of these 3 convergent boundaries?
Oceanic-Oceanic Convergent Plate Boundaries The denser oceanic crust subducts forming a trench
above the subduction zone.
CONTINENT-CONTINENT CONVERGENT PLATE BOUNDARY Continental crust will not subduct, results in the formation of a mountain range.
Mountain Range
CONTINENT-CONTINENT CONVERGENT PLATE BOUNDARY
- When an oceanic plate converges with continental, the denser oceanic plate subducts.
- This forms a trench above the subduction zone that runs parallel to the coastline and a volcanic mountain range along the continent's coast.
Oceanic-ContinentalConvergent Plate Boundary
When an oceanic plate converges with continental, the denser oceanic plate subducts. This forms a trench above the subduction zone in the ocean adjacent to the coastline and a mountain range along the continent's coast. The Andes Mountain Range

TRANSFORM PLATE BOUNDARY
THE SAN ANDREAS FAULT-This is an example of a transform plate boundary.-The 2 sides of this boundary move passed each other in opposite-horizontal directions.
