At the end of the syllabus content, we will also attach the link to download the latest Geology syllabus in PDF format.
Geology is the branch of Science that deals with the origin, interior and composition of the earth and primarily the rocks, their constituents as minerals, their structures and the way of their distribution has taken place on the continents and also on the ocean floor. It is not only the study of surface processes and surface geology but also various processes in the interior of the earth.
