This is a method of agriculture conservation that slows the wind by planting tall trees or grasses around an area:

• terracing

• contour plowing

• strip cropping

• windbreak

This layer of the soil profile is important because it grows our food as organic material breaks down:

• topsoil

• subsoil

• transition area

• bedrock
