🌱 Soil Formation & Processes
Explore how soil develops from rock and organic matter through weathering, microbial activity, and time. Learn about the key factors that shape soil composition and why soil formation is a slow, complex process that requires thousands of years to mature. **What you'll learn:** - How weathering breaks down parent rock into soil particles - Why organic matter and humus are essential to healthy soil - The role of climate, organisms, time, and slope in soil formation - How microbes and decomposers contribute to soil development
