why do we need to be concerned about the orientation of bedding planes and other sedimentary structures

It helps with stratigraphic studies.

Explanation:

Bedding planes are the sheets that distinguish each successive layer of a stratified rock from its preceding layer, also known as sedimentary planes or stratification planes.

When one layer of sediment that is completely different from the former is formed or created over the old layer, bedding is said to have occured. This new layer may comprise of sand and tiny stones (called pebbles) or other sedimentary material. Because the components of the each new successive layer are totally different from the former in terms of composition, there is a marked division between each of them identifable by their quality and colur.t

The study of each of these layers to ascertain their time scale which provides basis for studies in historical geology is called stratigraphic studies.

The initial placement of strata in geologically diverse terrains is suggested in stratigraphical studies and the depositional nature of the sediment is established.
