EROSION AND DEPOSITION Erosion Transportation of loose rocks and sediments (weathered material) Agents of Erosion 1. Primary Force of Erosion Gravity 2. Running Water • Streams and Rivers – most common type, greatest agent of erosion 3. Waves 4. Wind 5. Glaciers Deposition • Release of sediment when erosional agents lose their carrying power (ability to “hold” materials) Factors Affecting Deposition • 1. Particle Size • Larger particles settle first • 2. Shape • Smooth and round settle faster than flat and/or irregular ones (less friction) • 3. Density – • more dense settles first
