Geology

Geology is the science and study of the solid Earth and the processes by which it is shaped and changed. Geology provides primary evidence for plate tectonics, the history of life and evolution, and past climates. In modern times, geology is commercially important for mineral and hydrocarbon exploration, is publically important for predicting and understanding natural hazards, plays an essential role in geotechnical engineering, and is a major academic discipline. One who studies geology is called a Geologist.
