…and bumping, bubbling boundaries Plate Tectonics …and bumping, bubbling boundaries

Plate Tectonics The theory that explains how the solid lithosphere consists of a series of plates that float on the partially molten section of the mantle.

A is something that indicates the farthest limit, as of an area; border boundary

Plate boundaries are the location where different plates meet.

Geologic Action at Plate Boundaries

Transform Boundaries San Andreas fault zone, California

Divergent Boundaries Mid-ocean ridge Rift valley, Quiolotoa, Equador

Convergent Boundaries Subduction leads to trenches The Himalayan Mountains, Tibet

Use text pp. 42-47 to gather the information needed to complete your notes. EQ: What are the 3 types of plate boundaries described through the theory of plate tectonics? Type Characteristics Visual 2 plates slip past each other in the opposite direction Earthquakes often occur here transform 2 plates are moving apart Forms a rift valley, many happen at the mid-ocean ridge divergent 2 plates collide Can cause trenches or mountains convergent INB p. 11
