The lithosphere is broken into Tectonic Plates

• The lithosphere is made from the crust and the uppermost part of the mantle

• The lithosphere is rigid, brittle rock

• These plates float on the asthenosphere

How do the plates ACTUALLY MOVE?

• Convection currents in the asthenosphere drive the movement of lithospheric plates

Multiple Choice

Tectonic plates consist of

• continental crust

• mesospheric crust

• both continental and oceanic crust

• oceanic crust

Multiple Choice

_______________ Currents within the mantle cause the earth's plates to move and shift s molten material rises and falls due to density and gravity

• Convection
• Radiation
• Conduction
• Wind

Multiple Choice

How long did it take the continents to move from Pangaea into their current position?

• Hundreds of years

• Thousands of years

• Millions of years

Multiple Choice

What is a plate boundary?

• when two plates come together

• the second layer of earth

• ocean component

• continental drift

Divergent Boundaries

• Plates move apart

• Creates mid - ocean ridges and rift valleys

• Creates new crust through Seafloor Spreading

Seafloor Spreading

At a divergent boundary, two oceanic plates move apart. This allows mantle material to rise and cool, forming new crust. Older crust moves further away.

Transform Boundaries

• Plates slide past each other

• Creates faults

• Does not destroy or create crust

Convergent Boundaries

• Collide (crash into eachother)

• Create mountains, trenches, volcanoes

• Destroys crust during subduction

Subduction

At a convergent boundary, plates collide. Heavier (more dense) oceanic crust goes under and melts into the mantle. This destroys the crust.
