Kerala Plus Two Geology case studies
Kerala Plus Two Geology · Put your knowledge to work in context.
Kerala Plus Two Geology - the Higher Secondary Geology course examined by the Kerala Board of Higher Secondary Education - is a two-year senior secondary elective for students who want a science stream subject built around the solid Earth rather than around living systems or chemical reactions alone. It suits candidates who intend to continue into B.Sc. Geology, applied geology, earth science education, mining or civil-related fields, and also students who simply want a descriptive, observation-heavy science subject alongside Physics, Chemistry, Mathematics or Biology. The syllabus moves from Earth materials upward: physical geology and surface processes, mineralogy (crystal systems, physical properties, optical basics), the three rock families, structural geology and plate tectonics, fossils and stratigraphy, the geology of India with particular attention to Kerala's laterites, coastal plain and Precambrian shield, economic minerals, groundwater and environmental issues, and the practical skills of hand-specimen identification, map reading and field observation. The Kerala Plus Two Geology case studies are 5 cases and about 3,306 words.
