What is continental drift?
You tell me!
A theory that states continents were once one land mass: Pangaea.
A theory that states continents were once one land mass: America.
A theory that states continents were once one land mass: India.
What is used to support the Theory of Continental Drift?

What is the seafloor?
Portion of Earth's crust that lies beneath ocean water.
Portion of Earth's mantle that lies beneath ocean waters.

Which best describes the Seafloor Spreading Theory?
Material creates mid ocean ridges, which then carries seafloor apart. Magma flows into crevices and hardens.
Material pushes Africa from South America, India from Australia, etc.
Mountains are created that push continents away from each other.
Glaciers cause rifts in between continents.
What is the largest mountain range on the seafloor?

Mid-African Rift
Mid-African Ridge
Mid-Atlantic Rift
Which group best supports the Seafloor Spreading Theory?

Contour
What best describes the Theory of Plate Tectonics?
Lithosphere is broken into plates that move atop the asthenosphere.
The African Plate and Nazca Plate formed Pangaea.
Asthenosphere is broken into plates that move atop the lithosphere.
Lithosphere and asthenosphere collide.
Which type of plate boundary is incorrect?
Divergent (plates move away)
Convergent (plates collide into each other)
Transform (plates slide past each other)
Transform (plates transform into Optimus Prime)
What are features caused by tension forces?
Mid-ocean ridges, rift valleys, and faults.
Mid Atlantic Drift, rift valleys, and faults.
Mid ocean ridges, strike slip faults, and rift valleys.

What features are caused by compression forces?
Mountains and volcanoes.
Fault block mountains, fault lines, and faults.
The Rocky Mountains.
Volcanic islands and plateaus.
What best describes strike slip faults?
Plates slide past each other and stick / slide horizontally.
Plates collide and cracks open that magma soon fills.
Plates cause upwarped mountains.
Faults start to enlargen.
What is an area where an oceanic plate subducts into the mantle?
Subduction zone.
Convergent plate boundary.
Transform plate boundary.
Divergent plate boundary.

Between Mantle and Crust.
Between Inner Core and Outer Core.
Between Outer Core and Inner Core.
