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
