Earth’s Core

In the Symmesian world of Pellucidar, David Innes searches the jungle for Dian the Beautiful and attempts to unify the various tribes of beast-men, animals and dinosaurs into a loose federation.

In response to a radio plea from Abner Perry, a scientist who with his friend David Innes has discovered the interior world of Pellucidar at the Earth's core, Jason Gridley launches an expedition to rescue Innes from the Korsars (corsairs), the scourge of the internal seas. He enlists Tarzan, and a fabulous airship is constructed to penetrate Pellucidar via the natural polar opening connecting the outer and inner worlds. The airship is crewed primarily by Germans, with Tarzan's Waziri warriors under their chief Muviro also along for the expedition.

Scientists have made new inroads in the study of the Earth's deep interior. They have forged developments in this fascinating arena using experimental and observational techniques,. including seismology, monitoring of the Earth's rotation, geomagnetism, and accurate measurements of Earth's gravity fields. These techniques along with more theoretica

The Earth's Core, Second Edition is a six-chapter book that begins with the general physical properties of the Earth, with emphasis on the core-mantle boundary. 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. Subsequent chapters focus on reversals of the Earth's magnetic field; the energetics and the constitution of the Earth's core; and the cores of the Moon and other planets. The role of the Earth's core is vital to the understanding of many geophysical phenomena. It is the seat of the Earth's magnetic field and is responsible as well to some variations in the length of the day.

Paul Roberts' research contributions are remarkable in their diversity, depth and international appeal. Papers from the Paul Roberts' Anniversary meeting at the University of Exeter are presented in this volume. Topics include geomagnetism and dynamos, fluid mechanics and MHD, superfluidity, mixed phase regions, mean field electrodynamics and the E

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.

At the Earth's Core is a 1914 fantasy novel by American writer Edgar Rice Burroughs, the first in his series about the fictional "hollow earth" hollow earth It first appeared as a four-part serial in All-Story Weekly from April 4-25, 1914. It was first published in book form in hardcover by A. C. McClurg in July, 1922.

An expanded version of a course on the physics of the Earth's interior by an internationally recognised expert in the field. It is a reference text providing condensed information on those essential physical topics needed by both the non-specialist scientist and student to follow the most recent developments in internal geophysics. It is a key to understanding papers covering theoretical geophysics where the basic formulae, definitions and theorems cannot be explained in detail due to the limited space and thus enables the reader to remain aware of the continuous progress being made in studying the Earth's interior.

This volume contains papers given at a workshop on the earth's core boundary and geodynamos held at Liblice Castle, Czechoslovakia in 1988.

From the Earth's Core to Outer Space focuses on four themes: (1) Evolving Earth’s crust, (2) Changing Baltic Sea, (3) Climate Change, and (4) Planet Earth, third stone from Sun. The focus on these four topics provides both a state of the art review of earth science topics of particular importance to Scandinavia and the Baltic and also the global context in which a consideration of these topics must be made. It finishes by discussing our use of space born technologies for understanding these topics and places the Earth within the context of our neighbouring planets and their satellites. The first theme includes papers on the structure, origin and evolution of the Earth’s crust and in particular the ore deposits in Fennoscandia, plate-tectonic drift of Fennoscandia (Baltica), and postglacial isostatic rebound of the crust. The second theme contains papers dealing with changes in the ice season of the Baltic Sea, inflow and stagnation in deep basins, biology of the Baltic Sea, and carbon dioxide balance in sea water. The third theme deals with origin and evolution of oxygen in atmosphere, postglacial climate change, effects of aerosols and greenhouse gases on climate, interplay between anthropogenic and natural factors in the current climate change, and Earth’s water resources. The fourth theme includes articles on Earth’s space environment, use of satellites in cartography and geodesy, information obtained by space probes on Mars and other planets and their moons, and possibilities to find life on them.

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.

An interdisciplinary review of research in geomagnetism, aeronomy and space weather, written by eminent researchers from these fields.

E. Aster Bunnymund uses his martial arts skills, his network of tunnels, and the help of MiM, Sand Mansnoozy, and Nicholas St. North to battle the Nightmare King, Pitch, who has sent a venomous serpent to attack Bunnymund's royal guard of warrior eggs.

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 interelated, scientists gain and invaluable vantage from which to understans the evolution, dynamics, and state of the core. Earth's Core: Dynamics, Structure, Rotation presents a synthesis of current understanding in proactive analyses of Earth core phenomena, including research in core composition, wave-speed variation, magnetic field signatures, core mantle boundary issues, and more.

At the Earth's Core is a 1914 fantasy novel by American writer Edgar Rice Burroughs, the first in his series about the fictional "hollow earth" land of Pellucidar. It first appeared as a four-part serial in All-Story Weekly from April 4-25, 1914. It was first published in book form in hardcover by A. C. McClurg in July, 1922The author relates how, traveling in the Sahara desert, he has encountered a remarkable vehicle and its pilot, David Innes, a man with a remarkable story to tell.David Innes is a mining heir who finances the experimental "iron mole," an excavating vehicle designed by his elderly inventor friend Abner Perry. In a test run, they discover the vehicle cannot be turned, and it burrows 500 miles into the Earth's crust, emerging into the unknown interior world of Pellucidar. In Burroughs' concept, the Earth is a hollow shell with Pellucidar as the internal surface of that shell.

As the distance closed between him and those he went to investigate, his keen ears cataloged the sound of padding, naked feet and the song of native carriers as they swung along beneath their heavy burdens. And then to his nostrils came the scent spoor of black men and with it, faintly, the suggestion of another scent, and Tarzan knew that a white man was on safari before the head of the column came in view along the wide, well marked game trail, above which the Lord of the Jungle waited.

Tarzan at the Earth's Core is a novel by American writer Edgar Rice Burroughs, published in 1930, the thirteenth in his series of twenty-four books about the title character Tarzan and the fourth in his series set in the interior world of Pellucidar
