Which term best describes sediment that measures between 1 and 10 mm?

The term that best describes sediment measuring between 1 and 10 mm is gravel. Gravel is defined as sediment particles that range in size from approximately 2 mm (the smallest class of gravel) to 64 mm (the largest). While there may be some overlap in terms for sediment sizes, the specific range of 1 to 10 mm is generally considered to fall within the category of gravel, particularly closer to the lower end, as it is coarser than sand.

Medium sand typically measures between 0.25 mm to 0.5 mm in diameter, and fine sand is even smaller at around 0.1 mm to 0.25 mm. Pebble, on the other hand, is classified as sediment that starts from sizes above 4 mm up to 64 mm, thus would not encompass the 1 mm to 10 mm range effectively either. By understanding these classifications, it becomes clearer why gravel is the appropriate designation for sediment within this size range.
