Help please Determine whether each action will increase or reduce soil erosion.
cattle grazing
contour plowing
deforestation
hydroseeding
planting vegetation sort into either increse soil erosion or reduce soil erosion

Cattle grazing will increase soil erosion as it is removing the soil's vegetation and therefore exposing it more to the wind and rain.

Contour ploughing will help reduce soil erosion. By revolving the soil, and also planting after, but simply contouring can be enough, the capacity to withhold water, breaking its run-off will help contain the soil where it is rather than being pushed and taken away by water.

Deforestation will increase soil erosion by exposing the soil to water run-off and wind.

Hydroseeding can reduce soil erosion more than the sowing of dry seed, for example.

Planting vegetation reduces soil erosion as it creates protection to the soil from the weather and keeps it healthy for soil revolving animals that also contribute to reducing soil.
