Vocabulary Terms:
Convection currentsConduction currentsRadiationAsthenosphereSliding boundaryRift valleyColliding boundarySubduction
Sea-floor spreadingContinental drift-
Key Skills (Students should be able to):

Label the Earth’s layers on a diagram.

Locate the asthenosphere on a diagram. Identify

Describe which kind of plate boundary occurs when the sea-floor spreads.
Key Concepts:

Convection currents occur in the mantel and outer core.

Mi-ocean ridges occur at spreading boundaries.

In sea-floor spreading, the sea floor spreads apart along both sides of a mid-ocean ridge
as a new crust is added.

Convection currents move through the mantle.

Pressure increases inside Earth from the crust to the core.

The continental crust is made mostly of granite rock.

The oceanic crust is made mostly of basalt.
