Geology a science that examines the earth, its form and composition, and the changes it has undergone and is undergoing involves the knowledge of what happened before and the events occurring within the atmosphere requires not only a study of the materials found on earth but an understanding of the various geologic processes aims to develop an understanding of the earth’s materials and how these materials were changed and modified through the action of natural forces over a period of time
Geology as a Discipline
Two areas of Geology:
Physical Geology – deals with the study of the materials composing the earth and the processes and phenomena that operate beneath and upon its surface.
Historical Geology – deals with the study of the evolution of the earth. Physical geology precedes historical geology because we need to know how our own planet works before we attempt to open its past.
Astronomical Studies

    How has society responded to coastal changes initiated by sand transportation, and have these responses been wise environmentally and economically? What do you do when mid-latitude cyclones get larger, strong frontal winds are more frequent, and waves and currents get stronger? How can we control high waves and storm surges that drive more sediment transport, permanently changing the coast? Coastal dunes, of all shapes and sizes, are are dense enough to prevent rapid and significant changes…
