Contextualization

Geomorphology: A brief introduction

Our adventure begins with Geomorphology, a part of geography that studies the Earth's surface and its physical characteristics. This branch of science explores how mountains are formed, why rivers flow the way they do, and how winds and rains shape deserts and beaches. It is a study of the different terrains found on our planet and the processes that contribute to their formation and modification.

Terrains are not created equal. They vary in shape, size, and type, each with its own distinct characteristics. Moreover, they are also composed of different types of rocks, which play an important role in determining the type of terrain. Studying the different types of rocks, such as Igneous, Metamorphic, and Sedimentary, and how they interact with each other and with other elements of nature, allows us to better understand the formation of the terrain.

Geomorphology is fundamental in understanding various aspects of our planet. Humanity has long been using this knowledge in planning and executing various activities, from agriculture to civil construction and mineral exploration.

Why study Geomorphology?

We live in a world full of mountains, valleys, plateaus, and plains. Each of these formations has a direct impact on our lives, from where we build our homes and cities to where we plant our food. Understanding geomorphology helps us manage and protect the environment around us.

In this sense, in addition to its intrinsic value as a scientific area of knowledge, Geomorphology has important practical implications. For civil engineering, for example, it is essential to know the types of rocks and the structure of terrains before starting a construction. In agriculture, knowledge about the type of soil and terrain is crucial to determine the best planting and harvesting practices.

To delve into the topics of Geomorphology and its practical applications, students can explore the following resources:

• Joaquim Nabuco Foundation - Geomorphology
• InfoEscola - Geomorphology
• Portal Educação - Types of Terrain
• Mundo Educação - Types of Rocks

Practical Activity

Activity Title: Modeling Geomorphology

Project Objective:

The objective of this project is to understand the complex interactions between the geological processes that shape our planet and the different types of rocks that characterize these processes. We will do this by creating a three-dimensional model of a terrain with different types of rocks to represent a variety of formations and geological processes.

Detailed Project Description:

Students, divided into groups of 3 to 5 members, will research a specific type of terrain (mountains, plateaus, plains, etc.) and the types of rocks that are predominant in such formation. They will be encouraged to choose an existing terrain and make a detailed analysis of its geological characteristics. After conducting extensive research, students will use clay, paint, and other materials to create a physical model of the chosen terrain. The models should be colored according to the types of rocks found in the area.

Required Materials:

1. Clay or similar material for modeling
2. Colored paints
3. Brushes
4. Cardboard or base for the model
5. Research materials (books, internet access, etc.)

Detailed Step-by-Step for Activity Execution:

1. Form groups of 3 to 5 students and assign each group a type of terrain to research.
2. Start a detailed research on the selected terrain, focusing on geology and the types of rocks present.
3. After the research, sketch a plan for the model, indicating where the different types of rocks will be and the distinct characteristics of the terrain's geography.
4. Begin shaping the model using clay or other similar material.
5. Once the model is sculpted, start painting indicating the different types of rocks present.
6. Review if all the characteristics of the chosen terrain have been adequately represented in the model.
7. Document the model construction with a detailed documentation of the process, which will be used for the final report.

Group work is essential for this project, with various tasks that can be divided among students, such as: research, sketching, modeling, and painting.

This project should be developed over several weeks, with an estimated time of over 12 hours per student for research, model creation, and report writing.

Project Delivery:

The project delivery will include the physical model of the terrain and a detailed report documenting the entire research and model construction process.

The report should be structured in the following topics:

1. Introduction: Detailed description of the chosen terrain, its geological relevance, and the reason for its choice for this project.
2. Development: Explanation of the theory behind the geological characteristics of the terrain, the methodology used to build the model, and a discussion of the results obtained.
3. Conclusions: Lessons learned during the project execution, challenges faced and solved, and conclusions about the importance of studying geomorphology.
4. Bibliography: Sources used in the research for the project elaboration.
