The soil horizon that sits at the bottom is known as the "C horizon." This layer is composed of partially weathered rock and mineral material, forming the foundation for the other layers above. It’s like the basement of a house—sometimes overlooked, but crucial for holding everything up! Beneath the C horizon is the "R horizon," or bedrock. This solid rock layer is the last fortress beneath our feet, providing important minerals that eventually make their way into the soil above through weathering processes. Think of it as the ultimate hidden treasure waiting to be discovered!
