PPT-Sorting of Sediments and Deposition

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. 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.

Question #1. Describe how each of the landforms below contribute sediments to the Town Beach in Boomtown.. 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.. and . Stratigraphy. 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 . what grains can tell us. Most sediments contain particles that have a range of sizes, . so the mean or average grain size is used in description.. Mean grain size of loose sediments is measured by size analysis using sieves.
