As a general rule, if rock is just broken down through mechanical or chemical means, then weathering has occurred. ... Weathering and erosion are: Definition. is the movement of rock particles. Mechanical weathering is the breaking of rocks by expansion and contraction. A short reading passage explaining the difference between weathering, erosion and deposition. Web. Organic weathering happens when plants break up rocks … ‘the weathering and erosion of the limestone over millions of years has produced the characteristic form of the gorge’ Sediment is constantly being worn down by some type of weathering, carried away by an agent of erosion and deposited in a different place. What is weathering? On the seashore, the action of waves chips away at cliffs and rakes the fragments back and forth into fine sand. It’s the process of moving things from one place to another. Erosion is distinct from weathering which involves no movement. Water, wind, and other natural forces cause rocks and earth to wear away. The Weathering, Erosion, and Deposition PowerPoint to go over with the students. Define ‘erosion’. Describe the various types of mass wasting processes. The three main forces that cause erosion are water, wind, and ice. Weathering and erosion are two different, but related, processes. Mechanical weathering is the breaking of rocks by expansion and contraction. Diffen.com. Carbonation occurs on rocks which contain calcium carbonate such as limestone and chalk. Erosion definition, the act or state of eroding; state of being eroded. 4. Both weathering and erosion are geological processes. erosion meaning: 1. the fact of soil, stone, etc. A reading passage explaining the different types of weathering. is a chemical weathering process affecting Silicate minerals. Weathering and erosion are processes by which rocks are broken down and moved form their original location. Carbonation is the process in which atmospheric carbon dioxide leads to solution weathering. two very different processes that tend to act sequentially. You will learn how different rocks are weathered and eroded and the implications of this weathering. It is sometimes used interchangeably with weathering. However, the fundamental processes behind erosion and weathering are vastly different. These atmospheric conditions may be heat, pressure etc. The primary process in mechanical weathering is abrasion - the process by which clasts and other particles are reduced in size. -, http://www.pages.drexel.edu/~ks73/Weatheringanderosion.htm, Erosion is displacement of solids (soil, mud, rock and other particles) usually by the agents of currents such as, wind, water, or ice. See more. What's the difference between weathering and erosion? Factors that Effect Weathering Cold and Moist Warm and Moist - Creates more surface area where weathering can occur - Longer exposure = more weathering - Weaker rocks are less resistant and weather faster - Occurs on the surface where the rock is exposed to the atmosphere or hydrosphere. Weathering is the breaking down of rocks, soils, and minerals as well as wood and artificial materials through contact with the Earth's atmosphere, water, and biological organisms. When the glacier begins to melt, it deposits its cargo of soil and rock, transporting the rocky debris toward the sea. Carbonation occurs on rocks which contain calcium carbonate such as limestone and chalk.
