Water.
Detrital sediments would predominate in environments such as rivers, deltas, and beaches where erosion and transportation of rocks and minerals occur. These sediments consist of weathered fragments of pre-existing rocks and are typically deposited by the action of water or wind.
erosion, which is caused by wind or water
Deltas are created by pieces of rock being weathered, washed away by erosion and deposition at the mouth of the river where it meets an ocean. Beaches are created by deposition of sand by waves. Dunes are created by erosion of sand by wind.
If it doesn't have cracks in it it can still be weathered. Wind, water, hot, and cold can make the rock chip away.
Erosion
Mostly water determines but even wind helps in it.
The creation of energy is weathered material being moved by wind, water, or ice. . This is done by creating energy through kinetic movement. It also happens to be clean energy, due to absence of fossil fuels.
Erosion. Weathering is the physical and chemical breakdown of rock. Erosion is the removal of of weathered sediments. Transport is the movement of weathered sediments (say in suspension in river water) during the erosion process. Deposition is the laying down of the transported sediments in a new location.
A delta is formed when sediment is deposited at the mouth of a river. A valley is formed when a river runs through a flat surface, erodes the soil, and creates a depression. So delta=deposition and valley/canyon=erosion. I hope that helped!
The process by which wind and water remove and carry small pieces of weathered rock from one place to another is called erosion. This erosion occurs as the moving wind or water wears away the rock surface and transports the loosened particles to new locations. This movement of rock particles can lead to the formation of landforms such as valleys, river beds, and sand dunes.
Transportation of weathered rock can occur via flooding, river, glacier, wind, landslides, earthquakes, meteor impacts, and volcanism.
