1-5 Plate Tectonics (pp. 42-47)
∆Introduction (p. 42)

dropped on the floor similar?

The separate sections of the lithosphere are called p________.
Plates can carry c_________, the o________ floor, or both.

Faults – b_________ in the Earth’s crust where rocks have
slipped p_________ each other.
∆Plate Boundaries (pp 44-46)
Plate Boundary – the line where different p_________ of the
lithosphere meet
Rift Valley – Deep valley that f_______ where two plates meet.
3 types of plate boundaries
Transform Boundary – crust is neither created nor destroyed
Plates slip past each other in o___________
directions.
Earthquakes are frequent here. (California)
Divergent Boundary – 2 plates pull apart
(Mid Ocean Ridge) and r___________ valleys
(Great Rift Valley in Africa)
Convergent Boundary – 2 plates c___________ together
Can be continental plates, oceanic
Plates or both. (Himalayas)
What happens where two plates converge?
How do you know which plate will rise above the other, and which
one will sink down under the other?

So…what happens to two continental plates that collide?
Continental vs. continental = ____________________________

What happens to two oceanic plates that collide at a trench?
Oceanic vs. oceanic = deep ocean trench – __________________

And what happens when a continental plate collides with an oceanic
plate? _____________________________________________
