RATIONALE Plate Tectonics is the under-riding paradigm of modern Earth Science and plays a pivotal role in developing a student’s understanding of the Earth. This course will provide an introduction to the structure of the Earth and the principles of plate tectonics. The course will also begin building the key geological skills necessary for a first year undergraduate in observing, analyzing, describing and classifying crystals, minerals and rocks. The course is designed to develop the student’s knowledge base in geology/earth science at level 1 through lectures and tutorials. In practical exercises the student can use this knowledge base to describe and identify specific minerals and rocks and critically deduce their likely method of formation. An introduction to fieldwork is included to sensitize the student to the importance of field observation in geology and earth science. 1 COURSE DESCRIPTION This is a course in physical geology and introduces the study of earth materials and earth systems. It is the foundation for understanding how basic earth processes work and how rocks and minerals are formed. This course provides a basis upon which all other courses in the Geology major are built. It will also provide nonmajors with the essentials of earth science which are invaluable for disciplines, such as, Environmental Science and Material Science. This course introduces topics including: the structure of the Earth, its internal processes, and basic earth materials, minerals and rocks. A central focus of the course is on the paradigm of plate tectonics that is now seen as the unifying concept linking earth processes and materials in the rock cycle. Practical instruction will provide the basic skills of mineral and rock identification, and will also cover volcanic and seismic processes on broader regional and global scales. LEARNING OUTCOMES At the end of the course, the student will be able to: Describe and explain the fundamental structure of the Earth including the Earth’s compositional layering and layers of differing physical properties. Describe and justify plate tectonics theory, inclusive of: the types of lithospheric plate, the different types of plate boundaries; the movement of the plates, and how this is manifest in volcanism and seismicity. Identify specific modern mantle hotspots, and divergent, convergent, and transform plate boundaries, especially those in the greater Caribbean region. Describe and analyze minerals as crystalline solids and rocks as aggregates of minerals. Explain the basic structure of silicate minerals and the polymerization of silica tetrahedra.

These processes are central to developing a student’s understanding of how geological processes work and are used to explain the formation of different landforms in different environments. An appreciation of the history of the Earth is also crucial to geological thinking; students must be capable of rationalizing the development of the Earth, the changing processes that have shaped the planet, the development and evolution of life, and the values of absolute versus relative dating methods. The course is designed to develop the student’s knowledge base in geology/earth science at level 1 through lectures and tutorials. In practical exercises the student will use this knowledge base to identify features on topographic maps and produce topographic profiles. COURSE DESCRIPTION This course in physical geology involves the study of the different physical and chemical processes that operate within different environments and produce a range of geomorphological features on the Earth. The 3 course will cover the introductory aspects of physical geology including: weathering and erosion; landforms (rivers, slopes, coastlines, arid lands and glaciated environments); and the use of topographic maps. An appreciation of the processes acting on the Earth’s surface and how they can be used to interpret Earth history is central to understanding the global distribution of rocks, geologic features and earth resources. This course also provides an introduction to historical geology – origin of the Earth, origin of life on Earth, and the geological timescale – with an emphasis on using present geological processes to interpret the past. LEARNING OUTCOMES At the end of the course, the student will be able to: Describe the processes of weathering, erosion and soil formation. Define geomorphic features associated with landforms, rivers, slopes, coastlines, arid lands and glaciated environments.

An understanding of structural geology allows students to explain and predict the distribution of rocks and mineral resources. Such information is conventionally displayed on geological maps and the analysis and interpretation of geological maps (two-dimensional representations of a three-dimensional world) are key skills to develop. Students must also develop a deep awareness of how the exploitation of natural geological resources, the deposal of waste products, and various geological hazards are increasing affecting the world we live in. The course is designed to develop the student’s knowledge base in geology/earth science at level 1 through lectures and tutorials. Practical exercises will develop the student’s skills in presenting, analyzing and interpreting structural data and geological maps. The student will also develop an awareness of energy resources, environmental geology and hydrogeology. COURSE DESCRIPTION This course is a course in physical geology/earth science and provides students with skills to understand structural geology 8 and geological maps as well as providing an introduction to environmental geology, geological hazards and basic concepts of environmental pollution. In structural geology the student will learn how to describe, measure, and analysis planar and linear features in rocks, including folds, faults, and fabrics. Geological map interpretation will allow the recognition of how rock relationships are depicted on maps and practical classes will concentrate on the construction of geological cross-sections and the interpretation of geological histories. In environmental geology students will be introduced to the natural and anthropogenic physical and chemical factors that affect the environment, with topics including: climatic change and the combustion of fossil fuels; ocean pollution; toxic and radioactive waste disposal; land use management; geological hazards; water resources; and energy resources. Discuss the various forms of energy available including non-renewable and renewable forms. CONTENT This course will introduce the following topics Structural Geology: Folds, Faults and Fabrics and their relationships to Tectonic Settings; The interpretation of Geological Maps; Environment geology and pollution; Energy Resources: oil, gas, coal, nuclear, geothermal, hydro, solar, wind, tidal; Hydrogeology Pollution Liquid and Solid Waste Radioactive Waste COURSE DELIVERY METHODS LEARNING OUTCOMES At the end of the course, the student will be able to: Describe the different structural features, such as, folds, faults, joints in the field. Identify the different geologic structures on a geologic map and construct the cross-section and the sequence of occurrence of the different structural events. Discuss the tectonic settings under which the different geologic structures originate. Locate the different types of environmental hazards and their causes Explain the effects of coal and petroleum combustion on the environment. Define the hydrological cycle and the factors affecting the balance of the hydrological cycle. 9 Contact Hours Credit Hours Lectures 18 18 Practicals (12 × 2 hours) 24 12 Field Trip 6 3 Tutorials 6 6 Total 39 DELIVERY METHODS/APPROACHES Practicals will concentrate on understanding, analyzing and interpreting geological structures and geological maps.
