Geology is the study of the earth; the science that examines the earth, its
form and composition,and the changes which it has undergone and is undergoing.
Geologists employ mathematics, physics, chemistry, biology, and geography
to aid them in their study of the earth. Different aspects of the earth are studied
as volcanology, sedimentology, hydrogeology, glacial geology, structural geology,
minerology, paleontology, etc.
In this manual, we will examine some of the processes involved in the shaping
of the earth as we know it today. We will also examine the processes that have
shaped the earth in the past such as: life on earth, the formation of the earth, rocks and minerals, weathering and erosion, mass wasting, the work of water, glaciers, deserts, earthquakes, plate tectonics, oceans and mountains.
