A MAP OF EARTH'S TECTONIC PLATES. DIVERGENT PLATE BOUNDARY: - Plates move away from the mid-ocean ridge due to the direction the convection currents.

A MAP OF EARTH'S TECTONIC PLATES

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.
