In which type of geological formation are gorges most commonly developed?
Hard rocks
A gorge is a deep, narrow valley with steep, almost vertical sides. Gorges form mainly by river down-cutting (vertical erosion) when the river flows over hard, resistant rocks. Because the rock walls resist lateral (sideways) erosion, the valley remains narrow even as it deepens. Soft sediments and glacial till are too unconsolidated to support steep walls and tend to form broad valleys instead.
Hence, the correct answer is Hard rocks.
