Here's why:
* Vast quantities: Water exists in massive quantities on Earth, covering 71% of the planet's surface. This vast amount of water provides a significant force for moving sediment.
* Erosive power: Water has tremendous erosive power, especially in moving forms like rivers, waves, and glaciers. It can wear down rocks, break them into smaller particles, and transport them downstream, down coastlines, or across vast distances.
* Transportation capacity: Water can carry sediment of varying sizes, from fine clay to large boulders, depending on the flow velocity and the size and shape of the sediment particles.
While other agents like wind and ice can also move sediment, water is by far the most dominant force in sediment transport due to its abundance, erosive power, and transportation capacity.
