• Slide, Come Together, Spread Apart

• Porcelain, Plastic, Glass

• Mountains, Valleys, and Earthquakes

• Convergent, Divergent, Transform

Alfred Wegener was best known for ___________

• Continental Drift Theory

• Pangea Theory

• How dinosaurs became extinct

• Studying the Galapagos Islands

The Continental Drift Theory states that ...

• The earth has 4 parts

• Explain how the surface of earth is broken into pieces

• Continents fit together like a puzzle

What is the name of the "supercontinent"

• Earth

• Pangea

• Wegener

• Big Plate

What is a tectonic plate?

• The outer core

• Crust that moves on top of the mantle

• Continents that float on the water

What kind of crustal features do convergent boundaries make?

• Earthquakes, faults, fracture zones

• Rifts, volcanoes, valleys

• Mountains, volcanoes, islands

What kind of crustal features do divergent boundaries make?

• Earthquakes, faults, fracture zones

• seafloor spreading, rift valleys

• Mountains, volcanoes, islands

When 2 oceanic plates pull apart, magma rises, and new crust is formed at a divergent plate boundary pushes the continents apart

• Sea-floor spreading

• Convection

• Subduction

• Plates

What kind of crustal features do transform boundaries make?

• Earthquakes, faults, fracture zones

• Seafloor spreading, rift valleys

• Mountains, volcanoes, islands

Convection is....

• When hot air sinks and cold air rises

• Cycle of heating and cooling due to density

• When plates move
