How much has human history been influenced by the earth and its processes? This volume in the Science 101 series describes how both slow changes and rapid, violent, ones have impacted the development of civilizations throughout history. Slow changes include variations in climate, progressive development of types of tools and sources of energy, and changes in the types of food that people consume. Violent changes include volcanic eruptions such as the one at Toba 75,000 years ago, which may have caused diversification of people into different races, and the eruption of Santorini in 1640 BC, which may have destroyed Minoan civilization. Other disasters are Hurricane Katrina in 2005 and the tsunami in the Indian Ocean in 2004. Earth Science and Human History 101 describes basic principles of geology and shows how the earth affected history and is affecting present events. The volume has four sections: Processes in the atmosphere, oceans, and riversPlate tectonicsThe conflict between the evidence for evolution during the long history of the earth and the beliefs of creationistsResources and the environmentThe volume includes a glossary, numerous illustrations, and a bibliography of works useful for further research.

To this day, there is a great amount of controversy about where, when and how the so-called supercontinents--Pangea, Godwana, Rodinia, and Columbia--were made and broken. Continents and Supercontinents frames that controversy by giving all the necessary background on how continental crust is formed, modified, and destroyed, and what forces move plates. It also discusses how these processes affect the composition of seawater, climate, and the evolution of life. Rogers and Santosh begin with a survey of plate tectonics, and go on to describe the composition, production, and destruction of continental and oceanic crust, and show that cratons or assemblies of cratons became the first true continents, approximately one billion years after the earliest continental crust evolved. The middle part of the book concentrates on supercontinents, beginning with a discussion of types of orogenic belts, distinguishing those that formed by closure of an ocean basin within the belt and those that formed by intracontinental deformation caused by stresses generated elsewhere. This information permits discrimination between models of supercontinent formation by accretion of numerous small terranes and by reorganization of large old continental blocks. This background leads to a description of the assembly and fragmentation of supercontinents throughout earth history. The record is most difficult to interpret for the oldest supercontinent, Columbia, and also controversial for Rodinia, the next youngest supercontinent. The configurations and pattern of breakup of Gondwana and Pangea are well known, but some aspects of their assembly are unclear. The book also briefly describes the histories of continents after the breakup of Pangea, and discusses how changes in the composition of seawater, climate, and life may have been affected by the sizes and locations of continents and supercontinents.

First published in 1993, this book surveys both the history of the Earth and the nature of the processes that controlled its history. It integrates information from many fields to provide a comprehensive summary of an interdisciplinary topic. Fundamental processes such as convection, thermal evolution of the Earth, evolution of the crust, mantle, orogeny, and rifting are explained. Historical topics such as the origin of life, paleontologic extinction events, differences between the Archean and younger time periods, deposition of Precambrian sediments, and evolution of the atmosphere and oceans are discussed. The book then focuses on the development of modern ocean basins, the history of Phanerozoic orogenic belts, and the nature of cratonic sedimentary cover sequences. The book can be used as a reference to give an overview of earth history for readers in other research areas, and as a broad introduction to this vast subject for all interested in earth science.
