In This Lab You Will Use Topographic Maps And Online Satellite Images
In this lab you will use topographic maps and online satellite images to explore the terrain changes on Earth. Please keep in mind, those changes are caused by various geomorphic agents, including running water, ocean waves and tides, wind, glaciers, living plants and animals, through their erosion, transportation, and deposition work! In this lab, you will learn and appreciate the geomorphic processes operating on our Earth surface through three case studies. All answers should be directly filled into the geomorphology file, with each answer placed below each corresponding question.

Understanding Terrain Changes through Topographic and Satellite Analysis
In this comprehensive study, I will explore the dynamic processes shaping the Earth's surface by analyzing topographic maps and satellite images. The focus will be on understanding how geomorphic agents such as water, wind, ice, and biological activity influence terrain evolution through processes of erosion, transportation, and deposition. The analysis will be structured around three distinct case studies, each illustrating different geomorphic processes and landform developments.
Case Study 1: Fluvial Erosion and Valley Formation
My first case study involves a river valley profile captured via topographic maps and satellite imagery. The selected area displays characteristic features of fluvial erosion, including a defined river channel, alluvial fans, and terraces. The analysis reveals that running water is the primary agent shaping this landscape. The meanders and cut banks indicate active erosion, while depositional features suggest periods of sediment accumulation. Through the topographic profiles, we observe elevation changes consistent with down-cutting and lateral erosion processes. The satellite images demonstrate recent changes in river course, emphasizing the dynamic nature of fluvial landscapes.
Case Study 2: Coastal Erosion and Shoreline Changes
The second case study focuses on a coastal region affected by ocean waves and tides. Using satellite images and shoreline maps, I analyze the progressive retreat of the shoreline over time. Coastal erosion is evident where wave action causes sediment removal, leading to features such as sea cliffs, beaches, and barrier islands. The presence of wave-cut platforms and the recession of the shoreline illustrate ongoing erosional processes driven by wave energy. Tidal influences are visible in the shape and size of tidal flats and estuaries. Human interventions, such as seawalls, are noted where infrastructure impacts natural processes.
Case Study 3: Glacial Landforms and Ice-Related Erosion
The third case study examines a glacial landscape, characterized by U-shaped valleys, cirques, and moraines. Satellite images reveal the extent of glacial coverage and the erosional features left behind after glacial retreat. The ice acts as a powerful geomorphic agent, eroding bedrock through plucking and abrasion. The deposition of till and the formation of terminal and lateral moraines showcase the depositional work of glaciers. The observed landscape demonstrates how glacial processes contribute to significant terrain transformation, especially during ice advance and retreat cycles.
