jessica gabriel: Mucking around in the dirt

Reflection: Throughout the week I learned about soil profiles, structures, textures, pHs, Hydroponic systems, and fertilizers. It was important to learn how to see what soil is good, bad, or what needs improvement.

Vocabulary:There are two parts to SEDIMENTATION, DETACHMENT and TRANSPORT. Transport carries the soil away, while Detachment separates the soil. Sometimes Sedimentation runs into a GULLY or a RILL. A Gully is a samall valley orginially worn away by running water and serves as a drainage. A Rill is a small rivulet or channel.

Question: Is sedimentation based on the particles in the water or the color of the water?
