Answer:
A straw bale barrier lining the perimeter of a home construction site protects against erosion.
Step-by-step explanation:
- A straw bale barrier functions similar to a filter. It is porous only enough to let the water pass but the pores aren't big enough to let other particulate matter pass through it.
- When the water washes off the material that forms the surface layer of an area, erosion is said to have occurred.
- This particulate material is stopped by the straw bale barrier from flowing off and hence the site is protected against erosion.
