Explanation / Answer

The answer would be:

Size: boulders, pebbles

Sorting: moderately

Shape: rounded

The term, mountain front, is an imaginary borderline between a mountainous area and a low, gently dipping plain (either a pediment or alluvial fan). When mountain streams emerge onto a relatively flat lowland their gradient drops and they deposit a large portion of their sediment load. They are mostly rounded to semi angular in shape owing to the erosive transportation process. Coarser material is dropped near the apex of the fan, while finer materials are carried toward the base of the deposit, which is why the deposits appear moderately sorted.
