Mid-ocean ridges form when this happens

This is the cause of continental drift

This is what creates deep ocean trenches

The ocean floor is the newest at this topographic feature and the oldest and this other topographic feature

This is why magnetic stripes support the theory of plate tectonics

This is the type of boundary when two plates slide past each other in opposite directions

This feature forms at transform boundaries

This topographic features forms when two continental plates collides

These are 2 features that form at an oceanic-continental convergent boundary

These are 3 topographic features that form at divergent plate boundaries

This rock is formed when old rocks are changed by heat and pressure

This rock contains strata (layers) that keep a record of earth’s history

This type of rock makes up mid ocean ridges

This type of rock is most likely found in a subduction zone

These are 3 differences between extrusive and intrusive igneous rocks

This is the first step to cause an earthquake

A cinder cone volcano would likely form at this plate boundary

This type of earthquake occurs at transform boundaries

These are 4 differences between the Richter and the Mercalli Scale
