A(n) plain is formed where streams deposit fertile soil. a. scroll b. coastal c. glacial d. alluvial

The most appropriate answer is D. alluvial. A glacial plain is formed by the accumulation of till and other debris A coastal plain Would be formed by deposition and erosion from and by ocean waters A scroll plain refers to deposition of sediment from a meandering river, leaving sediment in areas of lower relief I suppose the answer could be a scroll OR an alluvial fan dependent on how specific the question intends to be and the material used to make the question. I would refer to a text to be 100% sure but alluvial is my guess.

Correct Answer is: D. Alluvial

Explanation:

Alluvial plains are landforms created by the deposition of sediments from a river and its floodplain, this deposits are exposed to different erosion conditions such as Physical weathering ( Rain and Wind) and as a result of these processed the soil will be formed, a soil rich in nutrients that where carried down by the river and will often be a fertile soil.
