Final answer:
Puddles on top of a mountain create pits due to the process of erosion.
Step-by-step explanation:
Puddles on top of a mountain create pits due to the process of erosion. When rainwater or snow melt collects in depressions on the mountain, it can slowly erode the surface material over time, forming pits or potholes.
For example, consider a snowy mountain. As the snow melts, it can gather in small depressions or crevices on the mountain's surface. Over time, the water can seep into cracks in the rock, and if the temperature drops, it can freeze. The expansion of freezing water can create enough force to break up the rocks, forming pits or potholes.
Similarly, when rainwater collects in depressions on the mountain, it can gradually wear away the rock or soil, creating pits or potholes.
