Water flowing over something still creates friction, albeit it's fluid friction. So while it won't wear as efficiently as grinding friction, it still does. Additionally, water dislodges objects and causes them to tumble into each other, which adds to the friction.
Water can chemically weather rocks by dissolving minerals, water can also physically weather rocks by fracturing them by hydraulic pressure or frost wedging.

Wind and water
Living things can contribute to chemical weathering by secreting organic acids that can break down minerals in rocks, roots of plants can physically break apart rocks, and by facilitating the growth of mosses and lichens that produce acids that break down rocks.
A mineral is a solid inorganic matter found in the earth that can break down when weathered. Minerals can be chemically altered or physically broken down through processes like erosion, temperature changes, and chemical reactions with water.
Erosion is the main force that acts on rocks to break them down into sand. Water getting into cracks, freezing and expanding also helps to break down rocks.
They erode by the effects of wind and water
Rocks break down into smaller pieces through a process called weathering. Weathering can be caused by physical forces such as wind and water erosion, or by chemical processes like acid rain or the growth of plants. Over time, these processes can break rocks down into smaller particles like sand, silt, and clay.
Sea water can chemically weather rocks through processes like dissolution and oxidation, which erode and break down rock minerals over time. The presence of salt in seawater can also lead to salt crystallization within rock pores, weakening and causing cracks to form. Erosion from waves and tides can physically break down rocks into smaller pieces through abrasion.
Floods can accelerate weathering by increasing the amount of water flowing over rocks and soil, promoting chemical reactions that weaken and break down rocks. The force of the rushing water during a flood can also physically erode and break down rocks, aiding in the weathering process. Floods can transport sediment and debris to new areas, contributing to further weathering as these materials undergo erosion and transport.
