describe what happened to the landscape without vegetation. (0:58)
how does vegetation affect erosion?

Explanation:

1. For the landscape with vegetation: The plant roots hold soil in place, so when water is poured, the soil stays stable, and the landscape shows little to no erosion or change.
2. For the landscape without vegetation: There are no roots to bind the soil, so water washes away loose soil, creating visible rills, carrying soil off, and altering the landscape's shape via erosion.
3. Vegetation reduces erosion by anchoring soil with roots, absorbing water to slow runoff, and shielding soil from direct water impact.

Answer:

1. Landscape WITH vegetation: When water was poured, the landscape showed almost no change; the soil remained intact because plant roots held it in place, preventing erosion.
2. Landscape WITHOUT vegetation: When water was poured, the loose soil was easily washed away, creating small channels (rills) and altering the shape of the landscape as soil was carried off by the water flow.
3. Vegetation reduces erosion: Plant roots anchor soil particles to prevent them from being carried away by water; vegetation also absorbs water to slow down surface runoff, and plant cover shields the soil surface from the direct impact of water droplets, all of which minimize soil loss.
