Soil erosion and sediment control is not a new technology The USDA Soil Conservation Service and a number of State and local agencies have been developing and promoting the use of erosion and sediment control devices for years This chapter provides Objectives. Learn basic concepts of sediment transport and fluvial geomorphology. Understand sediment budgets (sources, sinks, pathways for sediment). Discuss infrastructure and ecosystem response. 1. Chapter 4.1. Pages 118-127. Key Questions. How does moving water cause erosion?. What land features are formed by water erosion and deposition?. Moving water is the major agent of the erosion that has shaped Earth’s land surface.. Physical Weathering. Weathering. is the breakdown of rock or soil. . Physical . weathering occurs when natural forces, such as wind, running water, and moving ice, physically break up rock and soil into smaller particles. . The . surface. features of the Earth change as a result of observable physical and chemical processes . Weathering and Erosion. This is a monument . called Cleopatra’s . Needle. It was carved in Egypt around 1450B.C. The sides are carved with hieroglyphs, the writing of ancient Egypt. It stood in the dry, hot Egyptian desert for over 3000 years. During that time, the hieroglyphs remained distinct.. Water Erosion. How Does Moving Water Cause Erosion?. Erosion by water begins with a splash of rain.. Some rainfall sinks into the ground.. Some evaporates or is taken up by plants.. The rest of the water runs off over the land surface.. __________, ___________, and __________ act together in a cycle that wears down and builds up Earth’s surface.. ________, ___________, __________, _______, and ________ all cause erosion.. _______ causes mass movement, the process that moves sediment downhill..

J. Quigley. 4/2012. Water Shapes the Land. Water Shapes the Land. The Mississippi River is like a thousand dump trucks… every year it carries more than 300 million tons of sediment to the ocean! . This sediment is being washed away from the surface of the land and is called erosion.. Lesson 1. Water Erosion. How does Moving Water Cause Erosion?. Erosion is the process in which sediment that has been broken down through weathering is moved.. Agents of Erosion are:. Water. Wind. Glacial (ice). Chapter 9 - Section 3, 4, 5, and 6. How Water Erodes. Most sediment washes or falls into a river as a result of mass movement and runoff. Other sediment erodes from the bottom or sides of the river. Streams carry sediment in several .
