Question

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?
alluvial fan
loess
wave - cut cliff
cave

Explanation:

• An alluvial fan is formed when sediment is deposited at the bottom of a steeply - sloped river due to gravity. As the river flows down the slope, gravity causes the water to carry sediment. When the slope flattens (at the bottom of the steep slope), the water slows down, and gravity causes the sediment to be deposited, forming an alluvial fan.
• Loess is wind - blown sediment, not directly related to river - bottom deposition due to gravity in the context of a steeply sloped river.
• A wave - cut cliff is formed by the action of waves (not related to river and gravity in the described river - bottom context).
• A cave is usually formed by chemical weathering (e.g., dissolution of limestone by acidic water) or mechanical weathering over time, not by sediment deposition at the bottom of a steep river due to gravity.

Answer:

alluvial fan
