Description :

The book present The subject of this geology, from the Greek geo, "Earth," and logos, "discourse." It is the science that pursues an understanding of planet Earth. Geology is traditionally divided into two broad areas—physical and historical. Physical geology examines the materials composing Earth and seeks to understand the many processes that operate beneath and upon its surface (FIGURE 1.1). The aim of historical geology, on the other hand, is to understand the origin of Earth and its development through time. Thus, it strives to establish a chronological arrangement of the multitude of physical and biological changes that have occurred in the geologic past. The study of physical geology logically precedes the study of Earth history because we must first understand how Earth works before we attempt to unravel its past. It should also be pointed out that physical and historical geology are divided into many areas of specialization. TABLE 1.1 provides a partial list.
