Excerpt from Elementary PhysiographyDefinition. Physiography deals with (1) the solid part of the earth, the lithosphere, (2) the liquid part Of the earth, the water or hydrosphere, and (3) the gaseous part of the earth, the air or atmos phere. The land, the water, and all animal and plant life are affected by the atmosphere, while the water is related in many ways to the land and to the life of the globe. As to the lithosphere, physiography has to do with its surface only, a surface which has not always had its present form. It has been shaped and re - shaped by winds, rivers, waves, and ice. Volcanic forces, too, have had their part in building it up and tearing it down, and over and over again the outer part of the earth has been warped and wrinkled. It is this ever-changing surface which concerns man and life generally, and physiography has to do chie¿y with the surface of the litho sphere and with the relation of air and water to it.Physiography and geology are closely related. The history of the earth has been written in the rocks for the student of geology, and physiography deals with the latest chapter of that history, the history of the present surface.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
