What is the main similarity between an alluvial cone and an alluvial fan?
Answer and explanation
Correct answer: Both form when a stream deposits sediment after its slope decreases
An alluvial cone and an alluvial fan are depositional landforms formed where a stream leaves a steep valley or mountain front and enters gentler terrain. The sudden reduction in slope lowers stream velocity and carrying capacity, so gravel, sand, and finer sediment are spread outward. A cone is generally steeper and narrower, while a fan is broader, but the basic process is the same. Option C is correct.
