It consists of eight questions, of which five are to be attempted, with compulsory questions 1 and 5. Aspirants must select at least one question from each of the two sections (A and B) from the remaining six. The paper is designed to assess a candidate's in-depth knowledge of geological concepts, including isostasy, landforms, projection diagrams, remote sensing data, seismic zones, volcanic belts, Earth's origin theories, geomorphology, mineral deformation, and tectonites. This paper is crucial for candidates aiming for a career in forestry through the IFS examination.
(a) Discuss the characteristics and location of global volcanic belts. On an outline map of the World, show the volcanic belts by hatch marks over the terrain.
(b) Explain how parasitic folds are used in interpreting large-scale folding.
(c) Critically evaluate the different theories of origin of Earth and explain in detail the most accepted theory. Illustrate your answer with suitable sketches.
(a) Critically assess the role of geomorphology in evaluating the ancient and modern hydrological regime of a terrain. Elucidate your answer by taking examples from Indian fluvial systems.
(b) Discuss the spectral range, ground resolution and image swath of IRS series sensors.
(c) Describe the deformation mechanisms of minerals and rocks, and add a note on their characteristic features.
(a) Explain with the help of sketches how microstructures in porphyroblasts can be used to determine post-crystallization deformation. List five other features which are also indicative of such deformation.
(b) Describe the Low Earth Orbit (LEO) satellites and their typical applications.
(c) Define tectonites and describe the three types of tectonites with examples. Explain how each type of tectonite can be used to decipher strain.
