How do sediments eroded by water become more smooth and round

Liquid water is the major agent of erosion on Earth. Rain, rivers, floods, lakes, and the ocean carry away bits of soil and sand and slowly wash away the sediment causing it to become more round and smooth.

I hope this helps!

through friction.

Explanation:

The sediments rub together to become smoother. Sediments that are transported in a mass by water or stream are in motion with respect to the motion of the stream water. They bump into each other which makes extruding parts vulnerable to getting knocked off which makes these particles round.

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
