Which term refers to movement of sediment by water in jumps?

• A. Sediment
• B. Store
• C. Saltation
• D. Source

Answer: (C)

The movement of sediment by water in jumps is saltation. In rivers and streams, grains near the bed can be lifted briefly by turbulence or by impacts from other grains, travel a short distance as a hop or bounce, and then land again, potentially causing more grains to be ejected. This hopping motion sits between rolling along the bed (traction) and being carried completely within the water column (suspension), making saltation a key way that sand-sized particles move as bedload. The other terms refer to what the material is (sediment), where it is stored (store), or where it comes from (source), not the action of moving in jumps.
