Introduction to Geophysics


Free Download Introduction to Geophysics: Global Physical Fields and Processes in the Earth
English | 2024 | ISBN: 3031178661 | 403 Pages | PDF (True) | 111 MB
This textbook on geophysics is a translated and revised editon from its third German edition Einführung in die Geophysik – Globale physikalische Felder und Prozesse in der Erde.Explaining the technical terminology, it introduces students and the interested scientific public to the physics of the Earth at an intermediate level. In doing so, it goes far beyond a purely phenomenological description, but systematically explains the physical principles of the processes and fields which affect the entire Earth: Its position in space; its internal structure; its age and that of its rocks; earthquakes and how they are used in exploring Earth’s structure; its shape, tides, and isostatic equilibrium; Earth’s magnetic field, the geodynamo that generates it, and the interaction between the Earth’s magnetosphere and the solar wind’s plasma flow; the Earth’s temperature field and heat transport processes in the core, mantle, and crust of the Earth and their role indriving the geodynamo and plate tectonics.

Geologic Life Inhuman Intimacies and the Geophysics of Race


Free Download Kathryn Yusoff, "Geologic Life: Inhuman Intimacies and the Geophysics of Race"
English | ISBN: 1478030305 | 2024 | 608 pages | PDF | 14 MB
In Geologic Life, Kathryn Yusoff theorizes the processes by which race and racialization emerged geologically. Examining both the history of geology as a discipline and ongoing mineral and resource extraction, Yusoff locates forms of imperial geology embedded in Western and Enlightenment thought and highlights how it creates anti-Black, anti-Indigenous, and anti-Brown environmental and racial injustices. Throughout, she outlines how the disciplines of geology and geography–and their conventions: surveying, identifying, classifying, valuing, and extracting-established and perpetuated colonial practices that ordered the world and people along a racial axis. Examining the conceptualization of the inhuman as political, geophysical, and paleontological, Yusoff unearths an apartheid of materiality as distinct geospatial forms. This colonial practice of geology organized and underpinned racialized accounts of space and time in ways that materially made Anthropocene Earth. At the same time, Yusoff turns to Caribbean, Indigenous, and Black thought to chart a parallel geologic epistemology of the "earth-bound" that challenges what and who the humanities have chosen to overlook in its stories of the earth. By reconsidering the material epistemologies of the earth as an on-going geotrauma in colonial afterlives, Yusoff demonstrates that race is as much a geological formation as a biological one.

Avalanches in Functional Materials and Geophysics (2024)


Free Download Avalanches in Functional Materials and Geophysics by Ekhard K.H. Salje, Avadh Saxena, Antoni Planes
English | PDF (True) | 2017 | 310 Pages | ISBN : 3319456105 | 19.4 MB
This book provides the state-of-the art of the present understanding of avalanche phenomena in both functional materials and geophysics. The main emphasis of the book is analyzing these apparently different problems within the common perspective of out-of-equilibrium phenomena displaying spatial and temporal complexity that occur in a broad range of scales. Many systems, when subjected to an external force, respond intermittently in the form of avalanches that often span over a wide range of sizes, energies and durations. This is often related to a class of critical behavior characterized by the absence of characteristic scales. Typical examples are magnetization processes, plastic deformation and failure occuring in functional materials. These phenomena share many similarities with seismicity arising from the earth crust failure due to stresses that originate from plate tectonics.
