Question

Sedimentation increases with an increase in land used for agriculture.


Please select the best answer from the choices provided

True or False

Answer 1

True.

Converting natural vegetation to agricultural land typically increases soil exposure (from clearing, tillage, and reduced ground cover), which raises erosion and surface runoff. That runoff transports more soil and sediments into streams, rivers, and reservoirs, increasing sedimentation—unless conservation practices (cover crops, no-till, buffer strips, terracing) are used to limit erosion.
