(a)
Select ALL the reasons for plate movement.
Polar Reversal
Convection Currents
Ridge Push
Slab Pull

A mid-ocean RIDGE is located at the boundary of two tectonic plates. Which diagram correctly models the relative plate motion on each side of a mid ocean ridge?
The San Andreas fault is a transform fault. The map below shows a student's approximation of where the fault line crosses through the United States. Students were asked to make maps predicting which way land would most likely move over thousands of years.
The image shows a plate boundary. Arrows have been added to indicate the movement of the plates.What plate boundary feature is also shown?
A ridge formed by an inactive convergent boundary
A valley forming at an active divergent boundary
A fault forming at an active transform boundary
A volcano formed by an active transform boundary
This landform can occur at a divergent plate boundary.
ocean trench
mid-ocean ridge
tall mountains
transform fault
