2. I. Changing Surface A. Movement 1. Sediment = Material moved by erosion 2. Deposition = Build-up of sediment B. Gravity (Mass) 1. Landslides 2. Mudflow 3. Slump 4. Creep
3. II. Water A. Runoff Amounts 1. Rain amount 2. Vegetation 3. Soil Type 4. Shape of land 5. Human use
4. B. Types 1. Rills – Tiny grooves 2. Gully – Large groove 3. Stream – Gullies combine 4. River – Streams combine 5. Tributaries – Into major river
5. C. Erosion Waterfall 2. Flood Plains 3. Meanders – Curved flow in flat plain 4. Oxbow lake – Cut off from river
8. E. Ground 1. Caves i. Stalactite ii. Stalagmite 2. Karst
9. III. Moving Water A. Erosion 1. Abrasion – Wearing away rock with sediment 2. Load – Amount of sediment in river
10. B. Load Slope – Faster means more load 2. Volume – More water means more load 3. Shape – Deep stream is faster i. Turbulence – Multidirectional movement
11. C. Factors 1. Slower side leaves deposits 2. Faster side causes erosion
12. IV. Glaciers A. Types 1. Continental i. 10% of Land 2. Valley Glaciers i. High mountain snow fall ii. Motion cm to meters per day.
13. B. Shaping Land 1. Plucking 2. V-shape river to U shape valley 3. Deposits i. Till ii. Moraine – Edge of glacier iii. Kettle – Depression in surface
14.
15. V. Waves A. Erosion 1. Hitting shoreline 2. Abrasion 3. Worst at headlands
16. B. Deposition 1. Beach – Wave washed sediment 2. Longshore drift – Movement with current 3. Spit – Fingerlike projection of sand 4. Sandbars – Broken up spits
