PPT-Focus Task Describe the 4 types of erosion.

What are the landforms caused by erosion Friday 30 August 2019 What is a landform What do you think this means A landform is something that has been createdformed by natural processes Examples include a coastal stack. 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 Methods of soil conservation (ch3). The key aspects discussed in this chapter are:. Windbreaks. Contour ploughing. Stubble planting. Terraces. Stone walls. Reduce farming in dry weather. Windbreaks. Reforestation. Big . Idea 6:. Earth Structures. Description .   . Over geologic time, internal and external sources of energy have continuously altered the features of Earth by means of both constructive and destructive forces. All life, including . Weathering. The breakdown do the materials of Earth’s crust into smaller pieces.. Physical Weathering. Process by which rocks are broken down into smaller pieces by external conditions.. Types of Physical weathering. 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 . 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.. Waves strike the headland first.. Waves refract. around the headland and put . hydraulic pressure. on the sides of the headland.. Describe how sea caves are formed. (P. 48). The hydraulic pressure rips away sections of weakened rock.. Chapter 4.1. Pages 118-127. Key Questions. How does moving water cause erosion?. What land features are formed by water erosion and deposition?. The GREAT . BLUE. HOLE . p. 118. Where is it located?. formation of landforms. weathering and erosion. The process of weathering and erosion are the main forces behind landscape types. . However, they are not the only reason for a plain, plateau, or a mountain region to form. . 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. . 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. another.. 2 . kinds:. 1) . Rill erosion. is the erosion by running water in small channels. , on the side of a slope.. 2) . Gully erosion. is when a rill channel evolves to become deep and wide.. Aim: To be able to make links between resistance of geology and erosion rates. . Specification content. Starter . Whiteboards at the ready!. 1. Which rock type erodes the slowest?. IGNEOUS. 2. Name an Igneous Rock?. 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
