Learn more about the Earth and how weathering, erosion and deposition happens. While it is mainly caused by rainfall, inter-rill erosion can be accelerated by factors such as gradient, topography, vegetative cover, and climate. Examples of Water Erosion 1. For this, it is best to work in the kitchen. While there are several types of water erosion, they can generally be grouped into four major types: Inter-rill erosion describes the movement of topsoil by rainfall and its resultant surface flow. Soil erosion is the displacement of the upper layer of soil; it is a form of soil degradation. In partners or small groups, give the supplies to each group. They make model buildings either with a 3D printer or with LEGO® pieces and then see how their designs and riverbank placements are impacted by slow (laminar) and fast (turbulent) water flow over the soil. It depends largely on the kind of rainfall found experienced at any particular time or place. Hands on activities with experiments for third, fourth and fifth graders. The magnitude of water erosion depends on many factors, including the type of soil, the steepness of the slope, and the amount of vegetation in the area. Divide the class into four or six groups and have students number the paragraphs . A set of PowerPoint slides supports a lecture or class review of weathering and erosion. You can put a piece of chalk into a cup of vinegar or a couple of sugar cubes into a cup of water. 4. Underground streams can dissolve rock and create caves, and ocean waves can make coastal cliffs collapse. Earth Eclipse. Erosion is when tiny pieces of the Earth’s surface are moved from one place to another. Summary: Many landforms on Earth are the result of erosion and weathering. Sometimes a simple refresh solves this issue. Cancel anytime in 1-click on the manage account page before the trial ends and you won't be charged. Fact 3: Rivers and streams erode land in three ways depending on the velocity of the water. Over the course of many centuries, the water erosion managed to create a natural spectacle that attracts thousands of tourists every year. Activity 2 - Discovering erosion Its rate ranges from very slow to very rapid, depending on various factors such as the soil type, prevailing weather conditions, and the local topography. You get a zip file with:- the lesson plan with daily target, steps, 5. Flowing water curves out caves over thousands of years. A certain amount of erosion is necessary. The splash erosion activity shows how water erosion begins. The equipment we offer at Scientific Gear uses the Resistive Electrolytic technique and is manufactured by Novasina. activity and a close reading activity on Erosion.. Find Forest brooks and Mountain creeks in your explorations. Soil erosion may be a slow process that continues relatively unnoticed, or it may occur at an al… Have you seen small clods of sand being washed out or moved around by water? Click on the link to the left and watch the video about erosion. Water erosion comes in several different forms with various causes. Mudslides are caused by moving water and gravity, and happen in only minutes. It is however intensified and accelerated by human activities, such as inappropriate cultivation techniques and cropping practices, changes in Weathering : The process by which water, wind, and ice wear down rocks and other exposed surfaces. Erosion is when water actually transports rock and sediment from one place to another. Fact 1: A single rainstorm can wash away 5 tons of soil per acre. Weather, erosion, deposition activity water table (either commercial or teacher made one) or small rectangular pans (if using in small groups) Students bring in soil samples, âbareâ soil, grass covered soil, hose or watering can. Weathering and Erosion Science Lab Activity (Continued) Directions for â¦ In accordance with these agents, erosion is sometimes divided into water erosion, glacial erosion, snow erosion, wind (aeolean) erosion, zoogenic erosion and anthropogenic erosion. Look closely at the pictures and compare the 2 photos. Then show your child how shaking or stirring the cup -- in other words, moving the water over the chalk or sugar -- makes them dissolve faster. In our model we used flowing water to move soil. Otherwise you will pay just $10 CAD/month for the service as long as your account is open. Water erosion occurs when rain drops hit soil particles hard enough to dislodge them and wash them downslope. Students will be able to: Rocks break down from large pieces to smaller pieces by physical and chemical processes. Water and soil conservation measures, such as wooden dams, are very effective in reducing runoff and transferring sediment to the alluvial plain. The fast-moving particles gradually chip away at bedrock, promoting the erosion. In our model we used flowing water to move soil.
