Question

how can humans reduce erosion along a riverbank? choose 1 answer: a by increasing the amount of vegetation on the riverbank b by breaking up the soil on the riverbank into smaller pieces c by cutting down all of the trees on the riverbank

Explanation:

Riverbank erosion is caused by water flow displacing soil. Vegetation (like trees, grasses) has root systems that bind soil particles together, reducing the ability of water to wash away the soil. Breaking up soil into smaller pieces makes it easier for water to carry away, increasing erosion. Cutting down trees removes the root structures that hold soil, also increasing erosion.

Answer:

A. by increasing the amount of vegetation on the riverbank
