because it is dense
Clay has very small pore spaces
Because gravel has gaps that the water can travel through and clay is less likely to although water can still travel through it but slower
Gravel doesn't fit close together like clay soil particles do, slowing down water flow through mud. If you visualize gravel as a screen of 1/8th inch mesh and clay soil as a screen of 1/128th mesh ( 16 times smaller holes ) you can then easily understand that water flows very swiftly through the gravel screen compared to the fine particles of clay soils.
Water beetles move through the water by thrusting their legs back and forth. This allows them to quickly move and catch prey.
Water can easily move through sandy soils, wheras clay-rich soil is much harder for water to penetrate, so sandy soils are drier.
The wind does not move through water to any significant extent.
Rain and water cause water to move throughout the hydrosphere.
If you are asking about a garden water hose. This can move with the force of water traveling through it. It can also move from the temperature of the water it holds.
It spins to move through the water
Water is tranparent; light passes through it.
sea stars move through the water by emitting a fluid from the hole on their underside; it propels them through the water
Capillary action, transpiration, and root pressure move water up through the plant.
