The formation of new areas of oceanic crust which occurs through the upwelling of magma at midocean ridges and its subsequent outward movement on either side

• Subduction

• Transform

• Convergent

• Sea-Floor Spreading

Look at this image. What type of plate boundary is this?

• Divergent

• Complex or Uncertain

• Transform

• Convergent

The gradual movement of the continents across the Earth's surface through geological time

• Plate tectonics

• Continental Drift

• Earthquake

• Sea-floor Spreading

Mountains and Mountain ranges are created by what kind of plate boundaries?

• Continental - Continental Divergent

• Oceanic - Continental Convergent

• Oceanic - Continental Divergent

• Continental - Continental Convergent

What geologic feature/event you be most likely to find at a transform boundary?

• Rifts

• Mountains

• Valleys

• Earthquakes

Landform created at a divergent boundary on the ocean floor.

• Rift valley

• Trench

• Fault

• Ridge

The theory that continents were once connected but have separated or drifted apart.

• Continetal drift

• Plate tectonic theory

• Evolution

• Big Bang

It consists of the crust and the uppermost part of the mantle divided into plate tectonics.

• Asthenosphere

• Lower mantle

• Lithosphere

• Magnetosphere

Movement of hot rocks up and cooler rocks down forming a cyclical motion.

• Asthenosphere

• Convection current

• Boundary

• Fault

The term for all continental masses joined together during the early Earth.

• Pangea

• Fossils

• Subduction

• Convection
