Which landform results from variations in stream deposition rates?

💡 Explanation

An alluvial fan forms from sediment deposition as stream velocity decreases suddenly; because a radial decrease in transport capacity causes sediment to deposit rapidly, forming the fan-like shape; therefore it creates an alluvial fan, rather than other erosional formations.

• Which erosional pattern emerges when acidic groundwater percolation weakens cave structures?
• Which risk increases after a large inland earthquake ruptures along a transform vault zone far from coastlines?
• Which risk increases during rapid snowmelt in mountainous permafrost regions experiencing solifluction?
• Which risk increases when a city's sewage pipes cross a strike-slip fault?
• Which outcome occurs when crustal subduction ceases at depth?
• Which hydrological outcome is accelerated when overlying soil collapses into a sinkhole?
