A collisional boundary occurs where two land masses on plates are pushed together. Trying to occupy the same space, the land masses buckle and fold, creating mountain ranges. A transform boundary ...

Use Graphic 2 to discuss convergent, divergent, and transform boundaries. Explain why each of these boundaries has the particular observable phenomena the students have seen. 14. Have the students ...

The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways ...

New crust is continually being pushed away from divergent boundaries (where sea-floor spreading occurs), increasing Earth's surface. But the Earth isn't getting any bigger. What happens ...
