Final answer:
Rock strata with variations in properties erode dissimilarly even when exposed to the same environmental conditions due to differences in weathering resistance and erosion processes.
Step-by-step explanation:
Rock strata with variations in properties erode dissimilarly even when exposed to the same environmental conditions due to differences in weathering resistance and erosion processes. Physical and chemical weathering break down rocks into smaller pieces or dissolve them in water. This material is then transported away by wind, water, or ice, leading to variations in erosion patterns.
