Thousands of years from now, a continental plate begins to collide with an oceanic plate. which of the following landforms would
gregori [183]
As the two plates collide,the denserr oceanic plate will subduct under the less dense continential plate, causing the continential plate to arch up and form a mountain range.

Let's look into it one by one:

A. An underwater mountain range will will run along the boundary on the oceanic plate. - This is false.

As the oceanic plate subducts under the continential plate, there is no chance for the denser material to accumulate while subducting. What would be find instead is ocean trench.

B. A mountain range will form in the middle of the continental plate. - This is false.

Although pressure will be applied and there would be stress accumulating on the continential plate, the middle is very unlikely to be affected.

C. A mountain range will run along the boundary on the continental plate. - This is true.

As the subduction happens, the continential plate will accumulate as it is less dense. The rock would fold up to form mountain ranges. For example, Rockies is one off the mountain range along the plate.

D. A chain of islands will form along the boundary of the oceanic plate. - This is false.

Similarly to A. it is not possible for the plate to accumulate when it slides under the other plate.

Therefore the answer is C. A mountain range will run along the boundary on the continental plate.

Hope it helps!
