Question

the table below shows the densities of two oceanic plates at a convergent boundary.

plate	density ($\frac{g}{cm^3}$)
b	2.75

based on the information in the table, what will most likely happen as the two plates converge?

choose 1 answer:

a) plate a will be pushed below plate b.

b) plate b will be pushed below plate a.

c) both plates will be pushed upwards.

Explanation:

At convergent oceanic plate boundaries, the denser plate subducts (is pushed below) the less dense plate. Plate A has a higher density ($3.15\ \frac{g}{cm^3}$) than Plate B ($2.75\ \frac{g}{cm^3}$), so Plate A will sink below Plate B.

Answer:

A. Plate A will be pushed below plate B.
