The inner core is a planet within a planet: a hot sphere with a mass of one hundred quintillion tons of iron and nickel that lies more than 5000 kilometres beneath our feet. It plays a crucial role in driving outer core fluid motion and the geodynamo, which generates the Earth's magnetic field. This book is the first to provide a comprehensive review of past and contemporary research on the Earth's inner core from a seismological perspective. Chapters cover the collection, processing and interpretation of seismological data, as well as our current knowledge of the structure, anisotropy, attenuation, rotational dynamics, and boundary of the inner core. Reviewing the latest research and suggesting new seismological techniques and future avenues, it is an essential resource for both seismologists and non-seismologists interested in this fascinating field of research. It will also form a useful resource for courses in seismology and deep Earth processes.
With topics ranging from the structure of the core-mantle boundary region, to the chemical and physical properties of the core, the workings of the geodynamo, inner core seismology and dynamics, and core formation, this book offers a ...
This edition discusses the accretion mechanism, heat sources in the early Earth, time of core formation, thermal regime of the Earth, melting-point depth curves, and thermal consequences of iron-alloy core.
Describes how the Earth was formed, explains how scientists study the Earth's interior, and discusses how the makeup and movement of the mantle and core affect the surface.
Published by the American Geophysical Union as part of the Geodynamics Series, Volume 31. Geomagnetism, dynamo theory, seismology, geodesy, and mineral physics each present significant perspectives on Earth's core. When...
Explains how scientists use modern tools like seismology, geodesy, computer modeling, and GPS instruments to study the workings of the inner Earth.
Discusses the properties of the Earth's layers, explains how plate techtonics help to form the planets geographic features, and describes how earthquakes and volcanoes occur.
Explains what the center of the earth is made of and describes what the reader would need to dig to the core, including a special outfit and ship to survive the heat and pressure.
