outer core

Answer

convection currents

Answer

asthenosphere

Question 14

Difference between continental drift (CD) and plate tectonics (PT)

Accepted Answer

PT-explains how CD happened

PT-asthenosphere moves plates

Answer

CD-no evidence for it

Question 15

Subduction occurs when one plate slides beneath another plate. The figure below shows the process of subduction. Notice that the oceanic plate slides beneath the continental plate.

What happens when the crustal plates move as shown in the figure?

Accepted Answer

Volcanic mountain ranges form.

Answer

An ocean forms.

Answer

Sea-floor spreading occurs as the oceanic plate moves.

Answer

A transform boundary forms where the subduction occurs.
