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.
How Do Rivers Change the Land? Running water is a major factor in changing the surface of Earth.
Basins: land area that contributes water to a river system Divide: separates different drainage basins Ex. Drainage basin of Mississippi River 9: Running.
RIVER FORMATION EARTH’S GRAVITATIONAL FORCE PULLS OBJECTS TOWARD IT’S CENTER OF MASS. EARTH’S GRAVITATIONAL FORCE PULLS OBJECTS TOWARD IT’S CENTER OF MASS.
Chapter 3 Erosion and Deposition Suppose that you fill a jar halfway with layers of gravel, sand, and soil. Then you fill the jar with water, cover it.
EROSION- The transport of weathered materials….
EROSION AND DEPOSITION. Runoff and Erosion Precipitation over the United States averages about 75 cm per year. About 22.5 cm becomes runoff. Generally,
River Features Rivers are formed by erosion due to Running Water.
River Terminology 10/17/00. Erosion The break up and transport of earth materials by moving natural agents. Natural agents: Glaciers, Wind and Moving.
Section 1 Changing Earth’s Surface Erosion movement of weathered rock and soil from one place to another.
Water Erosion Chapter 3 Section 2. Standard S 6.2.a – Students know water running downhill is the dominant process in shaping the landscape S 6.2.a.
You have learned how to interpret how landforms are the result of a combination of constructive and destructive forces such as deposition of sediment and.
Chapter 9 Erosion and Deposition. Review terms and ideas ______________ is the material moved by erosion. SEDIMENT What materials does sediment consist.
Chapter 2: The Flow of Freshwater. Draw the water cycle diagram in your daybook and label it in your own words. p.41 in your text.
Guided Notes on Erosion and Deposition Section 7.2.
Chapter 9 Water Erosion and Deposition 9.1 Water Erosion and Deposition Notes Sheet.
Chapter 6: Erosion & Deposition. 6.1 Changing the Earth’s Surface Erosion: the process by which weathered rock and soil particles are moved from one place.
EXIT CHAPTER CHAPTER 13.1 Streams and Rivers 13.2 Stream Erosion and Deposition 13.3 River Valleys 13.4 Flood Plains and Floods CHAPTER OUTLINE Surface.
Running water: The major force of erosion acting on Earth today. If it weren’t for the mountain- building activity of plate tectonics, Earth would be completely.
Erosion and Deposition. Running Water is the most effective agent of erosion. Erosion is the process by which earth materials are moved by natural agents.
Erosion & Deposition Mr. Skirbst Life Science Topic 21.
Erosion Or... How to make molehills out of mountains.
Essential Questions How does moving water cause erosion? What land features are formed by water erosion and deposition? Chapter4 Lesson 1 Water Erosion.
A.Erosion – The transportation of weathered sediments 1. Agents of Erosion or Transport Systems: a. Running water b. Wind c. Glaciers d. Waves & Tidal.
The hydrologic cycle. Running water Streamflow Two types of flow determined primarily by velocity –Laminar flow –Turbulent flow Factors that determine.
Erosion and Deposition Do Now 1.What are the four main agents of physical weathering? 2.Give two examples of chemical weathering. 3.What factors influence.
Stream Erosion & Deposition Chapter 6 sections 1 and 2.
Stream Development. Objective 1. Define deposition as the process by which Earth materials carried by wind, water, or ice settle out and are deposited.
Rivers and Streams. River Systems A river or stream: any body of water flowing downhill in a well defined channel A river or stream: any body of water.
Water is responsible for a majority of all erosion on Earth Runoff - after rain the water remaining on the surface is called runoff. › As runoff moves.
Water Erosion “We’re changing Earth’s Surface!” A. Stream Erosion 1. Running Water 2. Energy 3. The water cycle -Most effective agent in wearing down.
Water Erosion Chapter 3 Section 2. Standard S 6.2.a – Students know water running downhill is the dominant process in shaping the landscape S6.2.b-
Surface Water Stream landscapes, erosion and deposition.
Erosion and Deposition Water Sculpting the Earth’s Surface.
Surface Water BIG Idea: Surface water moves materials produced by weathering and shapes the surface of Earth. Surface water moves materials produced.
Water Erosion. Moving Water Is the major agent of erosion that has shaped Earth’s land surface. The force of a falling raindrop can loosen and pick up.
AIM: What is a stream/river? Do Now: Answer the following questions in your notebooks. Where does the water come from that fills streams and rivers? Where.
Water Shapes the Land Objective: Explain how running water erodes the land. Water from precipitation soaks into the ground, evaporates, or flows.
11.1 The Active River. Do you think a river can have a source? Describe where you would expect to find a river’s source. The source of a river is where.
Water Erosion Chapter 3 Section 2 Pages Moving water is the major agent of the erosion that has shaped Earth’s land surface. Run-Off: The water.
Weathering and Erosion Unit 9. Weathering Sediments- rock particles that are carried by wind and water. Weathering- chemical and physical breakdown of.
Running Water. Includes all water that falls on Earth as rain or snow, and moves downhill Running water weathers the rock and erosion then follows Bedrock.
The Hydrologic Cycle PARTS OF A STREAM Channel - path of river Bed - bottom Head - beginning/source Mouth - ending Gradient - steepness of.
Streams A stream is a body of water that carries rock particles and dissolved ions and flows down slope along a clearly defined path, called a channel.
WEATHERING AND EROSION. Processes that change the surface of the Earth n Mechanical n Mechanical or Physical Weathering n Chemical n Chemical Weathering.
Rivers 11.1 – Zones in rivers From Miller’s Living in the Environment.
Running Water & Groundwater Chapter 6 (sec. 1 & 2 only) 200.
Runoff Streams Rivers Water picks up particles of clay, sand, and gravel as it moves along Earth’s surface Small grooves form – called rills.
By Water and Wind. Any natural process that removes sediments and carries them away from one place to another is called erosion. Gravity is the driving.
