The Earth’s tectonic plates float on top of the: (A) crust (B) lithosphere (C) upper mantle (D) lower mantle (E) asthenosphere</p><p>8. Less dense continental crust floats higher than more dense oceanic crust.

Two plates move toward each other ______boundaries. (A) divergent (B) lateral (C) convergent (D) transform (E) isostatic</p><p>15. Two plates slide parallel to each other at ______boundaries.

In some places two oceanic plates converge. One plate stays at the surface and the other plate dives down beneath it. This process is called: (A) convergence (B) subduction (C) divergence (D) transformation (E) rift formation</p><p>18. Sometimes down-going oceanic plates drag below continental plates.
