PPT-Deposition of sediments outpaces erosion and forms sandy be

Beach zone of loose particles that covers part or all of a shore US has about 11000 miles of beaches 30 of shoreline Beaches form at calm spots between headlands shores sheltered by barrier islands Outer Banks. Weathering. , Erosion and Deposition. . How can wind and water change our landscapes?. . Weathering- the . destructive processes . by which materials at or near the Earth’s surface are changed in color, texture, composition, firmness or form. . Agents of Deposition. 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.. Erosion by rivers, streams, waves, floods.. Rivers and streams often sort sediments. Large sediments are deposited upstream and small sediments are deposited downstream. . Floods to not sort sediments.. 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.. 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. 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. Contrast. the features left from different types of erosion.. Analyze. the impact of living and nonliving things on the processes of weathering and erosion.. Erosion and Deposition. Section 7.2. gravity: . What Is An . Ecoregion. ?. Ecoregion. - . a major ecosystem with distinctive geography, characteristic plants and animals, ecosystems, and receiving uniform solar radiation and moisture . Sometimes called an ecological region or bioregion. Finley’s 6. th. grade Science. Table of contents. How science works pg 1-2. Scientific Method pg 3-10. Science engineering and tech. pg 9-12.

Seaside Cliff – Seaside cliff is located above and just to the north of the Town Beach. When erosion moves sediments off of the cliff, they fall down to the beach area, adding material to the beach.. Aim: We must know and understand the following:. What do they look like? What factors influence their formation?. What is coastal erosion?. Specification content. Starter – .

What are Sediments. Sediments are loose Earth materials (unconsolidated materials) such as sand . which are . transported by the action of water, wind, glacial ice and .
