Answer:
In a region where the temperature is warm, rainy and has high humidity, there occurs frequent rainfall as the rate of evaporation and cloud forming processes are quite faster. This has a direct impact on landforms, especially in the hilly regions. It is because the water in this region is one of the factors that lead to the weathering and the erosion of the rocks. Weathering refers to the breakdown of the rocks and erosion refers to the transportation of the rock particles.
The rock minerals dissolve when reacts with the flowing water. The soft rocks are eroded more readily compared to the hard rocks. The carbonate rocks are also easily weathered and eroded.
Thus, water erosion is more likely to have an impact on the landforms in the hilly region, where the temperature is high and precipitation takes place frequently. It thus makes changes to the topography of the area.
