Overview
Alluvial fan systems are fascinating geological formations that arise from the deposition of sediment by flowing water. They typically occur at the base of mountains where rivers spread out, losing energy and depositing materials. These systems are not only important for understanding sediment trans...
Key Terms
Example: The alluvial fan at the base of the Sierra Nevada mountains.
Example: Sand and gravel are common types of sediment found in alluvial fans.
Example: Sediment is deposited at the mouth of a river, forming an alluvial fan.
Example: Erosion in the mountains contributes to sediment supply for alluvial fans.
Example: Rivers transport sediment downstream to form alluvial fans.
Example: The fan shape is created by the spreading of sediment as water flows out.
