Question

During her survey, Gabriella noticed upon closer inspection that there were preserved stream channels between the limestone layer and the sandstone layer, indicating significant stream erosion happened to the limestone before the sandstone was deposited on the limestone layer. No other geologic disturbance was observed or noted by Gabriella. Which type of geologic feature exists between the limestone layer and the sandstone layer

Answer 1
