Question

where may sediments be deposited? at a convergent plate boundary in a newly formed mountain at a divergent plate boundary in a river delta

Explanation:

Sediments are deposited in areas where the transporting agent (such as water, wind, or ice) loses energy. In a river delta, the river slows down as it enters a larger body of water (like a lake or ocean), causing it to deposit the sediments it was carrying. Convergent plate boundaries are areas of tectonic activity (subduction, mountain - building) which are more about destruction and deformation of rocks rather than sediment deposition. Divergent plate boundaries are associated with magma upwelling and new crust formation. Newly formed mountains are areas of uplift and erosion (initially), not sediment deposition.

Answer:

in a river delta
