Plate Tectonics

Identify the Major Plate labeled B

• African Plate
• Antarctic Plate
• Pacific Plate
• Eurasian Plate 

This boundary is described by two plates moving away from each other along the edges and separating. The resulting gap allows magma to rise and create new crust, forming new lithosphere.

• Convergent Boundary

• Divergent Boundary

• Transform Boundary

This boundary is described as two plates moving past eachother ALONG THE EDGES horizontally. These boundaries will get stuck or lock against each other causing earthquakes when they slip and release.

• Convergent Boundary

• Divergent Boundary

• Transform Boundary

This boundary is described as moving toward one another. When the plates are both continental plates they will crumple up and form mountains. When they are continental and oceanic plates, subduction occurs and earthquakes and volcanoes form.

Trenches, deep underwater canyons on the sea floor, are created at this type of boundary

Mid Ocean Ridge Formation  is created at this type of  boundary.

The process by which the ocean floor sinks beneath a deep-ocean trench and back into the mantle is known as _______

• convection

• continental drift

• subduction

• conduction

Most geologists think that the movement of Earth’s plates is caused by _______
