Weathering Erosion Deposition Science Lesson Changes To Earth Surface forces are natural phenomena that shape and reshape the earth’s surface. these forces contribute to the processes of weathering, erosion, and deposition. key learning objectives: – understand how surface forces shape the earth. – identify different types of weathering. – explain how erosion and deposition affect the landscape. Weathering, erosion, and deposition are important processes that shape the earth’s surface and create landforms, such as mountains, valleys, and cliffs. here are some of my favorite activities for slow changes to earth’s surface.

Ixl Changes To Earth S Surface Erosion 2nd Grade Science Explain weathering, erosion and deposition (w.e.d) and show how they all interconnect and interlink. for example weathering is the breaking down of rocks and minerals, erosion is the movement the weathered material and deposition is the dropping off of the eroded material. Wind, water, and ice can cause weathering and erosion because they all change earth’s surface. in order to tell the difference, consider whether there is breaking (weathering), or movement (erosion). The soil erosion in the area has affected local farmers and communities in the follow • the eroded land cannot be used for growing crops as there is no fertile soil left. • the eroded land will have no vegetation for the grazing of animals. • people have to move further away to find suitable land to farm and grow crops. Students investigate examples of each erosion type and discuss how erosion changes the surface of the earth. students also learn why engineers need to be aware of the different types of erosion in order to protect structures and landmarks from the damaging effects erosion can cause.

Ixl Changes To Earth S Surface Erosion 3rd Grade Science The soil erosion in the area has affected local farmers and communities in the follow • the eroded land cannot be used for growing crops as there is no fertile soil left. • the eroded land will have no vegetation for the grazing of animals. • people have to move further away to find suitable land to farm and grow crops. Students investigate examples of each erosion type and discuss how erosion changes the surface of the earth. students also learn why engineers need to be aware of the different types of erosion in order to protect structures and landmarks from the damaging effects erosion can cause. In this lesson students are provided with hands on experiments that teach about the different types of erosion. students rotate through four stations, with each station providing an experiment regarding one type of erosion. students fill out a science journal along the way. Students will use sand or sediment mixed with rocks to investigate agents of erosion (ice, wind, water, and waves) and their impact on the land. students will collect data and reflect on their experiences with erosion and deposition during their investigations. Do erosion patterns change with different types of sediment? what about a steep mountain versus a valley? water and earth’s surface erosion is a two part activity spanning multiple days. in the first part, students use a rock tumbler to explore the effect of weathering on different rock samples. • the land close to a gully cannot be farmed and therefore the land is not used; • gully erosion happens more on community owned land than privately owned land; • poor farming control such as overgrazing causes loss of vegetation cover.
