GL 101 introduces students to geology, covering topics like the structure and evolution of Earth, its atmosphere, biosphere, hydrosphere and lithosphere. It examines geological processes like weathering, erosion, transportation and deposition that shape the Earth's surface. It also discusses Earth's internal processes such as earthquakes, volcanism and plate tectonics.
GL 102 is a practical course that teaches students to interpret maps and conduct geological mapping exercises.
GL 103 introduces students to crystallography, mineralogy and petrology. It covers the identification and classification of common rock-forming minerals, economic minerals, igneous rocks, sedimentary rocks and metamorphic rocks. It also discusses fossils, their

100 LEVEL COURSES
GL 101 Earth Processes (3 credits)
Introduction to Geology. The universe, the solar system and the earth. Structure of the Earth. Earth's atmosphere, biosphere,
hydrosphere and lithosphere, their origin and evolution. Processes shaping the earth; the agents (rivers, oceans, glaciers and
wind), their actions (weathering, soil formation, erosion, transportation, mass movements and deposition) and the
landforms. Study of Earth's internal processes: earthquakes, volcanism, plutonism, deformation, orogenesis and
metamorphism, and their cause in the light of Plate Tectonics. Timescale of geological processes. Geological Time Scale.
Laws of Uniformitarianism and Superposition. Criteria to determine top and bottom of layered sequences. Unconformities.
Unravelling the past: relative and absolute dating, Geological history of Sri Lanka.
