Final answer:
The relationship between resistant and less resistant rocks in cliff morphology can have various effects, such as the protection of less resistant rocks by resistant rocks and the shielding of resistant rocks by less resistant rocks.
Step-by-step explanation:
The relationship between resistant and less resistant rocks in cliff morphology can have various effects. One of the effects is that resistant rocks can protect less resistant rocks by acting as a barrier against erosion. This can result in the formation of cliffs, where the resistant rocks remain intact while the less resistant rocks erode away. Another effect is that less resistant rocks can shield resistant rocks by absorbing the impact of erosion and preventing it from reaching the resistant rocks. Overall, the relationships between resistant and less resistant rocks play a significant role in shaping cliff morphology.
