Deposition
Learning Objectives
- Explain the process of deposition and how it contributes to the formation of landforms like deltas and sand bars.
- Describe the relationship between weathering, erosion, and deposition in shaping Earth's surface.
- Identify the key features of an estuary and how deposition can affect its structure and flow.
- Illustrate how deposition can alter coastlines and create new geological features over time.
Introduction and Hook
Introduce the concept of deposition by showing a short video clip of a river depositing sediments at its mouth.
Direct Instruction
Explain the processes of weathering, erosion, and deposition using diagrams and flowcharts to show their interrelationship.
Use the video 'The Grand Canyon' to illustrate how erosion and deposition have shaped this iconic landscape over millions of years.
Guided Exploration
Facilitate a class discussion on how deposition can alter coastlines and create new geological features over time.
Watch 'Lighthouse Lab – Coastal Erosion' to explore how human intervention can mitigate erosion while maintaining natural beauty.
Hands-On Activity
Conduct a hands-on activity where students create a simple model of a river and observe how deposition occurs as the water slows down.
Independent Practice
Assign students to research and present on a landform created by deposition, such as a delta or sand bar.
Check for Understanding
Use the 'Weathering, Erosion and Deposition' assessment to evaluate students' understanding of how these processes interact to shape the Earth's surface.
Review and Reflection
Reflect on how deposition contributes to the formation of landforms and its impact on the environment.
Assessment and Extension
Administer the 'Review – Processes That Shape the Earth' assessment to reinforce key concepts and assess comprehension.
