Soil Degradation AP Human Geography Quiz: Test Your Knowledge

📚 Quick Study Guide

🌍 Soil Degradation: The decline in soil quality caused by improper use, usually for agricultural, industrial, or urban purposes. 🌱 Erosion: The process by which soil and rock are removed from the Earth's surface by wind, water, or ice. It's a major contributor to soil degradation. 🚜 Agricultural Practices: Intensive farming, monoculture (growing the same crop repeatedly), and overgrazing can deplete soil nutrients and structure. 🧪 Chemical Degradation: Includes pollution, acidification, and salinization (increase in salt content), making the soil less fertile. 🌳 Deforestation: Removal of forests exposes the soil to erosion, reducing its ability to retain water and nutrients. 💡 Desertification: The process by which fertile land becomes desert, often due to a combination of climate change and human activities. 🛡️ Conservation Techniques: Practices like terracing, contour plowing, crop rotation, and no-till farming can help prevent soil degradation.
