The water can be chemically attacking the minerals contained in the rock, or be the medium which carries abrasive rock particles which weather solid rock. The power of moving water can tumble rocks into each other, rounding them and reducing their size, in the same principle as a rock tumbler. Crashing waves can pound into rock cliffs, reducing them to rubble, where they can be further weathered by the previously mentioned water effects. Pressures caused by freezing and thawing water in rock fissures will also reduce rock size.
Water, Waves, Glacier and Wind.

Any rock can wear away to form sediment; be it sedimentary, metamorphic or igneous.
Water fall
When wind or water wear away a rock, the process is called "erosion".

Weathering.
Constant erosion from wind and water makes the rock wear away. It's how canyons and mountains were formed.
Water, Waves, Glacier and Wind.
Abrasion is when rock particles are wearing away from the rocks surface. This is done by wind, water, and ice in nature.
The force of moving water alone can wear away particles of rock.
the water hits the rock and wears it down
yes, the force of the currents can slowely wear it down

Water fall
By the water scraping along it so often that little bits come off.
