Weathering vs Erosion Sort the actions into the correct column.

Which layer of this Soil Profile would be the least affected by or show signs of Erosion? 1 2 3 4 In the above Soil Profile Image, what layer is at location 3? A B C R What is Humus? Great with Pita Chips Organic Material Sediments Parent Rock Inorganic Material Why is Humus so important for Soil? It improves Water Filtration. It breaks down Oganic Pollutants. It is rich in nutrients, which is important for fertility. It converts Nitrogen into Nitrates, which are absorbed by Plants. What does the texture of "Sandy" Soil feel like?
