What is Geology
• The scientific study of the origin, history, and structure of the earth.
• The structure of a specific region of the earth's crust.
• A book on geology.
• The scientific study of the origin, history, and structure of the solid matter of a celestial body.
Geology is the study of the Earth, and in particular the history, the structure, the evolution of life, and the processes that have molded the Earth and its inhabitants. The coming of the space age has also extended the field to include the solid planets of the solar system. Although often attracted to the study of geology by an aesthetic appreciation and enjoyment of the earth, geologists commonly approach their studies from an interest either in the academic or the applied aspects of the science.
1. The academic aspects include the study of the history of life, the Earth, and the planets, and of the processes that drive the historical evolution.
The study of historical evolution through "deep time" is what fundamentally distinguishes geology from most of the other physical sciences. The study of the processes that drive this evolution can involve the application of any of the physical or life sciences to understanding the Earth. In this sense, geology is truly an interdisciplinary science.
The applied aspects of the science generally involve the interaction between humans and the earth. Applied studies include the study of mineral resources including oil and water; identification and mitigation of Earth hazards such as earthquakes, landslides, and volcanic eruptions; identification and mitigation of polluted ground water; and land use planning.
