This document explores the fundamental processes that shape the Earth's surface: Weathering, Erosion, and Deposition. It introduces these processes through engaging definitions and examples, explaining how weathering breaks down rocks into sediment, erosion transports this sediment via water, wind, and ice, and deposition refers to the dropping of particles when movement slows down. The document also features case studies like Mammoth Cave to illustrate these concepts in action, demonstrating how these processes have influenced the landscape over millions of years. Additionally, it invites reflection and understanding through thought-provoking scenarios and check-in questions.
