[Q]: - The movement is due to a combination of gravity acting on the sediment, and/or the movement of the fluid in which the sediment is entrained - Sediment transport occurs in natural systems where the particles are clastic rocks (sand, gravel, boulders, etc.), mud, or clay - The fluid is air, water, or ice - And the force of gravity acts to move the particles along the sloping surface on which they are resting - Sediment transport due to fluid motion occurs in rivers, oceans, lakes, seas, and other bodies of water due to currents and tides - Transport is also caused by glaciers as they flow - What might be the first step of the process?
