Question

which feature may form as a result of erosion related to runoff?
deltas
gullies
flood plains
stalactites

Explanation:

• Deltas form from sediment deposition at river mouths, not direct runoff - related erosion.
• Flood plains are areas adjacent to rivers that experience flooding, mainly due to water overflow rather than runoff - driven erosion.
• Stalactites form in caves from mineral deposition, not related to surface runoff erosion.
• Gullies are formed by the erosive action of runoff water cutting into the soil.

Answer:

gullies
