Front

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. Options: Convergent Boundary, Divergent Boundary, Transform Boundary

Back

Divergent Boundary

Front

This boundary is described as two plates moving past each other ALONG THE EDGES horizontally. These boundaries will get stuck or lock against each other causing earthquakes when they slip and release. Options: Convergent Boundary, Divergent Boundary, Transform Boundary

Back

Transform Boundary

Front

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.
