    Explore how environmental conditions and changes have had a profound effect on history. These classroom-ready activities show students how to apply the principles of earth science to events that have dictated America's past and present, f years ago to today. Such historical events as early migrations to and from North America, the building of the Panama Canal, and the Johnstown flood. The categorization of the past into discrete, quantified named blocks of time is called periodization. This is a list of such named time periods as defined in various fields of study. Major categorization systems include cosmological (time periods in the origin and mass evolution of the universe), geological (time periods in the origin and evolution of the Earth), anthropological and.

    Geologic history of Earth, evolution of the continents, oceans, atmosphere, and biosphere. The layers of rock at Earth’s surface contain evidence of the evolutionary processes undergone by these components of the terrestrial environment during the times at which each layer was formed. By studying. In the 19th Century, critical thought was extended even further into the domain of human social life by Comte and Spencer. Applied to the problems of capitalism, it produced the searching social and economic critique of Karl Marx. Applied to the history of human culture and the basis of biological life, it led to Darwin’s Descent of Man.

    History demonstrates that warmer is healthier. Since the end of the last Ice Age, the earth has enjoyed two periods that were warmer than the twentieth century. Archaeological evidence shows that people lived longer, enjoyed better nutrition, and multiplied more rapidly than during epochs of cold. Origin and Evolution of Earth Research Questions for a Changing Planet Questions about the origins and nature of Earth have long preoccupied human thought and the scientific endeavor. Deciphering the planet’s history and processes could improve the abil-ity to predict catastrophes like earthquakes and volcanoes, to manage Earth’s resources, and.
