PPT-Chapter 5 Erosion and Deposition

The ErosionDeposition Process Constructive vs Destructive Constructive process build up features on Earths surface Lave erupting from a volcano hardens and forms new land on the area where lava falls. Features of River Erosion. 1. Potholes. 2. River Valleys. 3. Gorges and Canyons. 4. Mesa and Butte. 5. Waterfalls. 1. Potholes. Potholes are formed due to stream or river erosion which initiates by simple . 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.. State what is meant by the term acid deposition and outline its origins.. Discuss . the environmental effects of acid deposition and possible methods to counteract them.. . acid deposition. Acid deposition refers to the process by which acidic particles, gases and precipitation leave the atmosphere . __________, ___________, 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.. (work funded through the Great Lakes Restoration Initiative). Dr. Mark Cohen. NOAA Air Resources Laboratory (ARL). College Park, MD, USA. Briefing Slides for GLRI Monthly Call. January 9, 2013. Atmospheric deposition is believed to be the largest . 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. 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: . Introduction to thin film deposition.. Introduction to chemical vapor deposition (CVD).. Atmospheric Pressure Chemical Vapor Deposition (APCVD).. Other types of CVD (LPCVD, PECVD, HDPCVD…).. Introduction to evaporation.. 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.. 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?. WHAT IS COASTAL EROSION? Coastal erosion is the endless reshaping of shorelines by waves, currents, tides, storms, ice, rain and groundwater seepage. Human activities, like construction, dredging, CO Md. Abdullah A. Mamun. Carlos Hernandez-Garcia. Matthew Poelker. P3 . Workshop : . Photocathode Physics for . Photoinjectors. , November 3-5, 2014. Lawrence Berkeley National Laboratory, Berkeley, California, USA.
