Answer:
The orientation of sedimentary rocks surrounding older igneous and metamorphic rocks in the Black Hills can vary. In general, sedimentary rocks tend to form horizontal or gently dipping layers. However, their orientation can be altered by tectonic forces, resulting in folded or faulted layers.
To determine the orientation of sedimentary rocks in a specific area, geologists study the rocks' physical characteristics, such as bedding planes, mineral composition, and texture, as well as their position relative to other rock units.
