Which hypothesis explains why continental plates have higher elevations than oceanic plates?

a. continental plates are less dense than oceanic plates.
b. oceanic plates are less dense than continental plates.
c. continental plates and oceanic plates have the same density but different mass.
d. continental plates and oceanic plates have the same

A. Continental plates are less dense than oceanic plates.

Explanation:

Continental tectonic plates have a lesser density than the oceanic plates, that's partly why they are higher.   Continental plates are also much thicker (40 km, 25 miles) than the oceanic places (6 km, 4 miles).

The oceanic plates are of course also pressed down by the weight of the oceans, which is a huge force.

A. Continental plates are less dense than oceanic plates.
