Question

question 16 of 25
which statement best describes subduction?
a. two plates move toward each other.
b. a less dense plate moves under a denser plate.
c. a denser plate moves under a less dense plate.
d. two plates slide past each other.

Explanation:

Subduction occurs when a denser tectonic plate (such as an oceanic plate) moves under a less - dense plate (like a continental plate). This is due to differences in density. Option A describes a convergent boundary in general, not specifically subduction. Option B is incorrect as it's the denser plate that goes under. Option D describes a transform boundary.

Answer:

C. A denser plate moves under a less dense plate.
