Answer:
Planting vegetation & reducing slope steepness
Step-by-step explanation:
Planting vegetation and reducing slope steepness can decrease soil erosion.
Philadelphia urban farms purchased their own soil instead of using the soil already there for fear of it could've been polluted
Soil erosion is a process where soil is moved from one place to another, often by wind or water. It can cause damage to the environment and can make it harder for plants to grow.
Imagine a playground with a slide that's too steep and doesn't have any
grass or plants around it. When it rains, the water carries away all the dirt
and makes it hard to play. But if you plant grass and reduce the steepness
of the slide, the water can't carry away the dirt as easily, and the
playground stays nice and fun.
Universal Soil Loss Equation:
Soil erosion =
rainfall intensity x slope length x slope steepness x soil erodibility factor
