Erosion Erosion = the transport of sediments from weathering. *Gravity and Water are biggest factors* 1. Streams 2. Glaciers 3. Landslides 4. Waves
Streams Running water carries sediment downstream Scours bedrock Carves V-shaped gorges.
Vocabulary Suspended Load = particles suspended in stream. Bed Load = particles rolling on bottom (abrasion polishes rocks). Discharge = amount of water flowing past a given point.
Sheet Erosion = flows in sheet over flat land.
Rill and Gully
Stream Evolution 1.Youth = head, high elevation, steep slope, rapid erosion, V-shaped valley 2.Middle Age = Small streams merge to form tributaries, gentler slopes, stream begins to meander.
Old Age Gentler slope, meander widens, reaches mouth. Mouth = where stream meets ocean or lake. Sediment deposits form delta or alluvial fan.
Erosion and Deposition
9: Running Water Basins: land area that contributes water to a river system Divide: separates different drainage basins Ex. Drainage basin of Mississippi.

Chapter 9 Water Erosion and Deposition
Unit 2: Erosion and Deposition by Water
HYDROLOGIC CYCLE Precipitation Runoff or infiltration(groundwater flow and plant uptake) Flow to and/or gather in basin Evapotranspiration into air Condensation.

Chapter 6: Erosion & Deposition
Objectives Describe how surface water can move weathered materials.
Rivers are formed by erosion due to Running Water.
A.Erosion – The transportation of weathered sediments 1. Agents of Erosion or Transport Systems: a. Running water b. Wind c. Glaciers d. Waves & Tidal.
RIVER FORMATION EARTH’S GRAVITATIONAL FORCE PULLS OBJECTS TOWARD IT’S CENTER OF MASS. WATER FALLING DOWN A SLOPE IS EVIDENCE OF GRAVITY. AS OBJECTS DROP.
