Geology is a discipline that studies the solid aspect of our planet earth. These are rocks that the surface of the earth is composed. It also studies the transformation of the Earth's surface over time. It analyses the historical and physical structure of the earth as well as the chemical and physical properties of materials that are found under the surface of the Earth. These include minerals, water, and gas. The modern definition of the term Geology includes Hydrology and the Atmospheric Sciences and hence it is considered as a major part of the integrated Earth System Science and the overall Planetary Sciences.

Geology is closely related to other disciplines like Physics, Maths, Chemistry, Geography, and Biology. Students pursuing Geology as a degree identify and assess environmental problems and try to develop ways in which they can be prevented or minimized. Besides theoretical knowledge, students also gain practical experiences in the field. Since Geology seeks to study the evolutionary history of our planet and integrate several other subject areas, hence, its reach is very elaborate. This broadens its areas of specialization in addition to its scope of employability.
