Plate Tectonics

Convergent Plate Movement can create

• Rifts
• Mountains
• Ocean Ridges
• Radiation

Divergent Plate movement can create

• Convection Currents
• Conduction
• Mountains
• Rifts and ocean ridges

The movement of metals within the earth's outer core cause a ____________________________ that is detectable on the earth's surface using a compass

• Gravitational Pull
• Volcanic Eruption
• Magnetic field
• Convection Current

During sea floor spreading, molten material rises up from the mantle...

• along the continents
• at the mid ocean ridges
• deep ocean trenches
• at north and south poles

NGSS.MS-ESS2-3

Thinner, more dense, younger crust, primarily basaltic, making ocean floor

• mantle

• continental crust

• oceanic crust

• asthenosphere

The portion of the earth's crust that primarily contains granite, is less dense than oceanic crust, and is 20-50 km thick

• mantle

• continental crust

• oceanic crust

• asthenosphere

The process that creates new seafloor as plates move away from each other at the mid-ocean ridges

• stressing

• seafloor spreading

• subduction

• shearing
