3. Which type of plate bounciary occurs where two plates are moving away from each other? a. Convergent boundaries b. Transform boundaries c. Static boundaries d. Divergent boundaries

The correct answer is: **d. Divergent boundaries** **Explanation:** - **Divergent Boundaries** occur where two tectonic plates are moving away from each other. This movement allows magma from beneath the Earth's crust to rise to the surface, creating new crust as it cools. Examples include the Mid-Atlantic Ridge. - **Convergent Boundaries** are where two plates move towards each other, which can result in one plate being forced beneath the other in a process called subduction, or in the formation of mountain ranges. - **Transform Boundaries** involve plates sliding past one another horizontally, which can cause earthquakes. The San Andreas Fault in California is a well-known example. - **Static Boundaries** is not a standard term used in plate tectonics. **Therefore, when two plates are moving away from each other, they are at a divergent boundary.** **Answer:** d. Divergent boundaries
