PPT-Erosion & Deposition

The creation of sedimentary rocks Weathering and Mass Movement Objectives 1 Describe the processes by which erosion wears down and carries away rock 2 Distinguish between chemical and mechanical weathering. California Deposition Reporters takes pride in our reporters by providing you with experienced reporters who arrive early to court and depositions, and provide the kind of service dictated in the professional atmosphere in which they take the spoken word and put into print witness' testimony utilizing the many tools utilized in today's market. They are then able to provide to you in many formats the transcripts either electronically or on paper. With scanned, linked and searchable exhibits.

The agents of erosion are also agents of deposition.. Depositional rate depends on sediment size, shape and density.. Depositional rate also depends on characteristics of the depositional agent.. 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.. 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.. Deposition. is the process whereby sediments. are “released” or “fall out” of an . erosional system.. River Delta. Glacial Moraine. Sand Dune. Barrier Island. Factors. that Impact . Deposition -- Velocity. pH Scale. PRIMARY POLLUTANTS (sulfur dioxide & nitrogen oxides) are emitted by combustion.. Primary pollutants can travel as far as 1,000 km. .. As the primary pollutants react with H. 2. O vapor and O. Weathering. Weathering is the process that breaks down rock and other substances at the Earth’s surface. . Heat, cold, water, and ice all contribute to weathering.. Repeated freezing and thawing for example can crack rock apart into smaller pieces. . 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). Scenario #1. Flood water pounds against a canyon wall and wears it down.. Weathering. Scenario #2. Rain washing soil away from a hillside. Erosion. Scenario #3. Layers of sediment forming at the bottom of the ocean. . (“Flow-Assisted”. . or “Flow-Accelerated”. . Corrosion). An increase in corrosion brought about by a high relative velocity between the corrosive environment and the surface.. Removal of the metal may be:. Predict how weathering might reshape surface features (topography). Weathering and Erosion. The top part of the lithosphere—the earth’s surface—changes as rocks are broken down to smaller pieces and carried away.. - running water is the most effective agent of erosion. - gravity draws surface water downhill, which allows the water to erode soil and rock materials. - rivers also eventually leave their eroded materials behind, which we refer to as . V-Map. 1 side for chalk. 1 side for . m&m’s. . Do Now. SWBAT describe mechanical weathering. 1. Where do pebbles and small particles of rock come from?. 2. . Did anyone carve pumpkins this weekend?.
