Explain why each of these boundaries has the particular observable phenomena the students have seen. 14. Have the students turn in their two annotated plate boundary maps.

destructive plate boundaries (margins) are formed. Constructive plate margins close constructive plate marginAn area where two tectonic plates are moving away from one another. are where tectonic ...

These convergent boundaries also occur where a plate of ocean dives ... Earth's mantle rises toward the surface and pushes apart two or more plates. Mountains and volcanoes rise along the seam.

In regions of convergence, one plate can sink under another in a subduction zone, or two colliding plates can form a mountain belt. At divergent boundaries, plates move away from each other and ...

plate tectonic activity takes place at four types of boundaries: divergent boundaries, where new crust is formed; convergent boundaries, where crust is consumed; collisional boundaries, where two ...

Transform boundaries neither create nor consume crust. Rather, two plates move against each ... To the west of the fault is the Pacific plate, which is moving northwest. To the east is the North ...
