Correct statements: 1, 3, and 5.
- Erosion can lead to increased sedimentation in local rivers and waterways — True. Soil washed into streams raises turbidity, clogs channels, and deposits silt downstream.
- Erosion can lead to loss of fertile land for farming — True. Erosion removes nutrient‑rich topsoil, reducing productivity and causing farmland degradation.
- Erosion can lead to loss of local species such as fish — True. Sedimentation and habitat changes harm spawning grounds and reduce oxygen/food availability for aquatic species.
Why the others are not generally correct:
- “Increase in available land for businesses and homes” — Generally false; erosion removes land rather than creates it (though deposition can build new land in some places, this is not the usual or reliable outcome).
- “Increase in fertile land for farm use” — Rare/context‑specific: deposition can create fertile alluvial soils in some areas (deltas, floodplains), but overall erosion more commonly reduces agricultural land quality.
