True
Match the following practices with their corresponding categories to prevent soil erosion:
Planting trees as windbreaks = Agriculture Keeping animals away from stream banks = Grazing Animals Reducing the amount of land that is logged and mined = Logging and Mining Avoiding using off-road vehicles on hilly lands = Recreational Activities
Match the following strategies with their corresponding benefits to prevent soil erosion:
Terracing = Decrease surface water runoff on steep slopes Rotate crops = Keep soil more fertile as it is used season after season No-till or low-tillage farming = Keep soil in place by disturbing the ground as little as possible Planting nutrient-rich cover crops = Provide long-term improvements to soil
Match the following practices with their corresponding methods to prevent soil erosion:
Leave leaf litter on the ground in the winter = Agriculture Cut only small areas at one time and quickly replant logged areas = Logging and Mining Invest in and use new technologies for parking lots = Development Move animals throughout the year = Grazing Animals
