Gravity, the force that pulls objects toward the center of Earth, can sometimes have a significant impact on the rate of erosion, thereby increasing the rate of deposition. Which feature is most likely impacted by gravity because it can form at the bottom of a steeply sloped river?

An alluvial fan forms where a steep river or stream flows onto flatter ground. Gravity helps move sediment downhill, and when the water slows at the bottom of the slope, it deposits that sediment in a fan-shaped pile. Loess is wind-deposited silt, a wave-cut cliff is shaped by ocean waves, and a cave forms through processes such as rock dissolution.
