Physical Geology

PHYSICAL GEOLOGY Physical Geology is that part of the science which deals with the form and constitution of the accessible portion of the earth, and studies the nature of the processes that have been at work in the past and are still moulding and modifying the earth's surface. The term has to be interpreted very widely, in order to avoid unnecessary and confusing subdivisions of the subject, and physi cal geology has of necessity to take cognizance of all other parts of geology, as well as of mineralogy and of physics, chemistry, biology, etc.---which have a direct bearing on it. The relationship between physical geology and physical geography is very close.

Physical-geology also entails some acquaintance with the general principles of meteorology, since climate is a factor of great importance.
