Which layer is made of the crust and upper mantle?

• Outer Core

• Inner Core

• Asthenosphere

• Lithosphere

The crust and the upper mantle are both the rigid layers of the Earth that make of the lithosphere. Why do scientists group them together even though they have different chemical compositions?

• they travel at different speeds

• they have the same chemical properties

• they have the same physical properties

• they have different thicknesses

Convection currents are the driving force behind the movement of tectonic plates. In what layer of the Earth do these convection currents occur?

• Asthenosphere

• Lithosphere

• Outer Core

• Inner Core

What creates the magma that erupts from volcanoes in subduction zones?

• Tears in the crust allow magma to rise to the surface.
• Materials on the oceanic plate subduct, melt and evaporate and rise to the surface of the crust.
• The heat from friction between the two plates causes the continental plate to melt.
• None of the above.

What is the best explanation for why oceanic crust is subducted by continental crust?

• The oceanic crust is cooler than continental crust.
• Continental crust is denser than oceanic crust.
• Oceanic crust is denser than continental crust.
• The oceanic crust is hotter than continental crust.
