What is the primary objective of erosion and sediment control?

Increase the amount of soil exposed
Minimize the extent and duration of soil exposure
Enhance soil nutrient content
Use chemical agents for soil stabilization

The correct answer is: Minimize the extent and duration of soil exposure

The primary objective of erosion and sediment control is to minimize the extent and duration of soil exposure. This is crucial because exposed soil is more susceptible to erosion by wind and water, which can lead to soil loss and the transport of sediments into nearby water bodies. By reducing the amount of time that soil is exposed to these elements, erosion and sediment control practices aim to protect the environment, preserve soil health, and maintain water quality. Effective methods might include the use of ground cover, silt fences, and other techniques designed to shield the soil from erosive forces. This not only helps protect the site during construction activities but also contributes to broader environmental management goals by preventing sediment pollution in waterways.
