Geology is the science that deals with the Origin, age physical structure and substance of the earth, their history, and the processes which act on them. (i.e. Evolutionary History of the Earth). Considering the earth’s Crust(containing rocks and minerals) which does not form simultaneously with the Core and the Mantle. Much of the growth history of the Earth’s early Crust staring from the date when the Earth evolved as a solid body to about 4000 million years ‘before present’ is speculative as we generally do not find any preserved records of rocks of that age on the earth’s surface whereas the rocks formed later are well preserved.
Evolution, modification and extinction of various surface and sub-surface physical features (like mountains, plateaus, plains, valleys, basins).
And also encompasses many different phenomena, including plate tectonics, volcanoes and earthquakes, and the long-term evolution of Earth’s atmosphere, surface and life.
Similarly the study of all the water bodies existing on the surface or underground i.e. the hydrosphere, which forms a important part of geology. The Interaction of the Hydrosphere, Lithosphere and the atmosphere, including the processes involved and the results produced due to such interactions also fall in the domain of the science of Geology.
Geology also includes the study of physical dynamic and physic-chemical processes operating on and within the earth.
Because of the ever-increasing demand for resources, the growing exposure to natural hazards, and the changing climate, geology is of considerable societal relevance. This course introduces students to the basics of geology. Through a combination of lectures, labs, and field observations, we will address topics ranging from mineral and rock identification to the origin of the continents, from geologic mapping to plate tectonics, and from erosion by rivers and glaciers to the evolutionary history of life.
