CHSE Odisha Elective Geology study plan

Define and classify the three major rock types (igneous, sedimentary, metamorphic) with at least two examples each

Sketch and label the rock cycle, identifying the processes that transform one rock type into another

Explain the difference between minerals and rocks, listing the five criteria for a substance to be a mineral

Identify the eight most common rock-forming minerals by their physical properties (hardness, cleavage, luster, color, streak)

Describe the internal structure of the Earth (crust, mantle, core) with depths, compositions, and densities

Explain the theory of plate tectonics, including evidence from continental drift, seafloor spreading, and paleomagnetism

Differentiate the three types of plate boundaries and the geological features associated with each

Summarize the elastic rebound theory and the difference between focus and epicenter, and between P, S, and surface waves

Outline the geological time scale (eons, eras, periods, epochs) with key events and approximate dates for each era

Apply the principles of stratigraphy (superposition, original horizontality, cross-cutting relationships, faunal succession) to interpret a sequence of rock layers

Explain relative and absolute dating methods, including radiometric dating and half-life calculations

Describe the major mass extinctions and their possible causes, and the evidence used to support them

Identify and describe the major types of folds (anticline, syncline, monocline) and faults (normal, reverse, strike-slip) with their stress regimes

Explain the formation of mountains, rift valleys, and ocean basins in the context of plate tectonics

Summarize the causes and effects of earthquakes and volcanoes, including hazard mitigation strategies

Interpret a simple geological map showing strike and dip symbols, and construct a cross-section from it

Describe the processes of weathering, erosion, transportation, and deposition, and distinguish between physical and chemical weathering

Explain the formation of soils, their profiles, and the factors affecting soil formation

Outline the hydrological cycle and the geological work of rivers, including erosion, transportation, and depositional landforms

Compare and contrast the geological work of groundwater, glaciers, wind, and waves, with characteristic landforms for each

Classify ore deposits by origin (magmatic, hydrothermal, sedimentary, residual) and give examples of important ores for each

Explain the formation of coal and petroleum, including the conditions required and the concept of source, reservoir, and cap rock

Describe the distribution of major mineral and energy resources in India, with at least five specific locations

Discuss the environmental impacts of mining and the principles of sustainable resource management

Define the scope of engineering geology and list the geological factors considered in site selection for dams, tunnels, and bridges

Explain the causes, types, and mitigation of landslides, and the role of geology in landslide susceptibility mapping

Describe the geological considerations for groundwater exploration and the difference between aquifers and aquicludes

Summarize the principles of environmental geology, including waste disposal, pollution, and natural hazard management

Synthesize all topics by creating a one-page summary sheet of key definitions, classifications, and processes

Solve 20 mixed practice questions (multiple choice and short answer) covering the full syllabus under timed conditions

Review and correct all errors from practice questions, explaining the correct reasoning for each

Recite the geological time scale and the rock cycle from memory, and list the main ore deposits of India
