Question

describing plate tectonics
which statement accurately describes plate tectonics?
pieces of the lithosphere move quickly and constantly.
the motion of subduction drives plate movement.
when one plates slides under another, it is called a convection current.
the lithosphere is broken into sections called plates.

Explanation:

• Analyze each option:
• Option 1: Lithospheric plates move slowly, not quickly, so this is incorrect.
• Option 2: Plate movement is driven by convection currents in the asthenosphere, not subduction motion, so this is incorrect.
• Option 3: When one plate slides under another, it's subduction, not a convection current, so this is incorrect.
• Option 4: The lithosphere is indeed broken into sections called tectonic plates, which is the correct description of plate tectonics.

Answer:

The lithosphere is broken into sections called plates.
