Question

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

plate | density \\(\left(\frac{\text{g}}{\text{cm}^3}\
ight)\\)
--- | ---
a | 2.85
b | 3.20

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 B has a higher density ($3.20\ \frac{g}{cm^3}$) than Plate A ($2.85\ \frac{g}{cm^3}$), so Plate B will be pushed below Plate A.

Answer:

B. Plate B will be pushed below plate A.
