Activity 1: What Is Plate Tectonics?• The Earth’s surface is broken up into

15 lithospheric plates. • These plates are composed of the top

part of the mantle and the crust. • There are oceanic plates (more dense)

and continental plates (less dense). • These plates “float” on the

asthenosphere, the plastic-like flowing part of the mantle.

PLATE TECTONICS: the theory that states that

pieces of the Earth’s lithosphere are in slow constant motion, driven by convection currents in the mantle

The Earth’s plates are constantly moving. What are some ways they may interact with each other?

a. come together (collide) b. move apart (separate) c. slide past each other

Transform Boundaries

• An area where two plates slip past each other, moving in opposite directions

• Example – the San Andreas Fault in CA.

• Earth’s crust is neither created nor destroyed.

• Earthquakes occur along these boundaries.

Divergent Boundaries

• An area where two plates move apart• Occur on land and on the ocean floor• Example – the Great Rift Valley in East

Asia.• New crust is created along the boundary in

an ocean, or a deep valley is created on land.

(Valley could fill with water…new ocean) • In oceans, ridges form. Constructive Boundary

Convergent Boundaries

• An area where two plates come together.

• Example – the Himalaya Mountains in Asia• Collisions occur a. cont. into cont. - (mountains) b. cont. into ocean - (trench) subduction c. ocean into ocean - (trench) Destructive Boundary

Subduction Zone

• An area where an oceanic plate converges with a continental plate.

• Can happen where two oceanic plates collide

• The Ring of Fire in the Pacific Ocean. • The dense oceanic crust sinks below the

less dense continental crust forming a deep trench.

• Ocean crust is forced back into the mantle, sometimes forcing molten rock upward forming volcanoes.
