Where is Earth's heat energy most concentrated?

• the mantle

• the lithosphere

• the core

• the crust

Which of the following best describes the location of the mantle?

• above the crust

• between the crust and the lithosphere

• between the crust and the core

• beneath the core

What is the underlying force that drives plate tectonics?

• ocean tides

• volcanic eruptions

• the rock cycle

• convection currents

• pressure

• heat

• density

The diagram below shows the collision of an oceanic plate and a continental plate. Collisions between oceanic plates and continental plates are thought to result primarily from

• hot liquid magma in the inner core

• convection currents in the mantle

• volcanic eruptions along coastlines

• meteor impacts in the ocean basins
