On a mountain front with sudden slope change which deposit may show decreasing particle size outward?
Answer and explanation
Correct answer: Alluvial fan
The correct answer is B, an alluvial fan. When a stream leaves a steep mountain valley and suddenly enters flatter land, its gradient and carrying energy decrease. Coarse gravel and sand are deposited near the fan apex, while finer sand, silt, and clay are carried farther outward. A stalactite is a cave deposit, a sea stack is a coastal erosional feature, and a cirque is a glacial hollow.
