Sediments can be deposited by wind or water but water moves most. Loess is wind deposited particles. Alluvium is water deposited soil. The particles are one part but the place they settle impacts how they become rock because the geologic process will be different at the bottom of a deep marine sea than it is in a shallow off shore shelf.
Only the very smallest particles will be moved to mid-ocean but there will be many plankton and other organic deposits.
Coastal particles will vary in sizes . Water temperature will have more impact on the organic contributions here. Shallow tropical waters have coral and can form limestone.
