Allyson Eno. Unit designed using. The Brain Based Teaching Model (. Hardiman. , 2003). Background Information. First Grade Unit. Duration: 5 weeks. Primary Years Programme Curriculum. (PYP). Unit under the Transdiciplinary Theme:. 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.. Allyson Eno. Unit designed using. The Brain Based Teaching Model (. Hardiman. , 2003). Background Information. First Grade Unit. Duration: 5 weeks. Primary Years Programme Curriculum. (PYP). Unit under the Transdiciplinary Theme:. After Unit 9 you should be able to:. Accurately identify common types of weathering. Understand what types of weathering are associated with certain climatic conditions. Be able to identify resistances to weathering in bedrock diagrams. 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. . What is Weathering?. The scenes of the world are continuously mutating. Sun, rain, frost, and wind are breaking down even the most solid of the rocks into smaller bits before they are taken away. This process is termed as weathering. . Geomorphology (. GEO 301).
