It is a basin
Explanation:
The Midwestern region is made up of sedimentary rocks because it is a basin. In a basin, sediments accumulates and they form sedimentary rocks there.
- Sedimentary rocks are rocks that are laid down in natural depression on the earth surface.
- These depressions serves as the collection point of sediments from different sources.
- When wind, water glaciers brings materials here, they settle and accumulate.
- Compaction, cementation and lithification of sediments occur here and sediments are transformed into sedimentary rocks.
Therefore, the Midwestern region must have been a basin for sedimentary rocks to have formed there.
