This PowerPoint is LOADED! Content from this weathering and erosion PowerPoint has been used at academic levels ranging from 6th grade enrichment science to introductory level geology classes at the university level. What makes this PowerPoint special is the QUIZ (assessment) at the end that is scored on a sliding justification scale. In this portion, students interactively choose the best weathering type based on the image and instructional discussion about the image. Answer choices vary because many processes are taking place/have taken place at similar times.
Content addressed in this PowerPoint includes:
Differentiation between weathering and erosion
Mechanical weathering processes: frost action, ice wedging, exfoliation, wetting and drying, plant and root action, abrasion, and spheroidal weathering
Chemical weathering processes: oxidation, carbonic acid, hydrolysis, and natural acids
Differential weathering and erosion
Erosional processes and specific agents
25 question QUIZ with a sliding scale answer key
