Earths Core

Earth’s Core: Geophysics of a Planet’s Deepest Interior provides a multidisciplinary approach to Earth’s core, including seismology, mineral physics, geomagnetism, and geodynamics. The book examines current observations, experiments, and theories; identifies outstanding research questions; and suggests future directions for study. 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 multidisciplinary perspective on what we know and what we know we have yet to discover. The book begins with the fundamental material and concepts in seismology, mineral physics, geomagnetism, and geodynamics, accessible from a wide range of backgrounds. The book then builds on this foundation to introduce current research, including observations, experiments, and theories. By identifying unsolved problems and promising routes to their solutions, the book is intended to motivate further research, making it a valuable resource both for students entering Earth and planetary sciences and for researchers in a particular subdiscipline who need to broaden their understanding. Includes multidisciplinary observations constraining the composition and dynamics of the Earth’s core Concisely presents competing theories and arguments on the composition, state, and dynamics of the Earth’s interior Provides observational tests of various theories to enhance understanding Serves as a valuable resource for researchers in deep earth geophysics, as well as many sub-disciplines, including seismology, geodynamics, geomagnetism, and mineral physics

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

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.

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.

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.

Telepathic birds, cavemen and prehistoric monsters. Not exactly what you would expect to find at the centre of the Earth! 'At the Earth’s Core' is the first novel in Burroughs’ fantasy series about the fictional Hollow Earth land of Pellucidar. The narrator finds a strange machine and its engineer in the Sahara desert, from whom he learns about the machine’s objective. Popularizing the concept of the "Hollow Earth" in fiction, Burroughs depicts a haunting subterranean world of endless oceans, vast jungles, and bizarre weather conditions. The author expresses the ludicrous and ridiculous beliefs of the seventeenth and eighteenth-century scientists that the earth was hollow, explaining some of its anomalies. "At the Earth's Core" was made into a movie in 1976 starring Doug McClure and Caroline Munro. The vivid natural descriptions, terrific adventures, and fascinating characters make this novel a must for fans of Burroughs and the fantasy genre. Edgar Rice Burroughs (1875-1950) was an American author, best known for his novel ‘Tarzan of the Apes’ (1914) and its sequels, as well as the Barsoom series. During World War II, he was one of the oldest U.S war correspondents. Tarzan and his adventures are loved by both young and old, and are evergreen classics. Many have watched at least one Tarzan TV series or movie with the most popular probably being the Walt Disney animation film from 1999 and "The Legend of Tarzan" from 2016 starring Alexander Skarsgård and Samuel L. Jackson.

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.

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.

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.

Edgar Rice Burroughs' 1914 pulp fantasy epic comes to life! Follow David Innes and Abner Perry as they take their "iron mole" five hundred miles below the Earth's crust to a world known as Pellucidar. Thrill as they cross paths with the evil Mahar, the ape-like Sagoths, and all manner of prehistoric creatures . . . as well as the lovely Dian the Beautiful! More than simply an epic adventure, At the Earth's Core is also one of Burroughs' most compelling love stories.

Forget the bunny trail.…In this addition to the groundbreaking series from the legendary William Joyce, Guardian E. Astor Bunnymund is on the warpath. Pitch, the Nightmare King, and his Fearlings had been soundly driven back by Nicholas St. North and company in the first Guardians’ adventure. But now Pitch has disappeared completely—and out of sight does NOT make for out of mind. It seems certain that he’s plotting a particularly nefarious revenge, and the Guardians suspect he might have gone underground. But how can they find him there? Enter E. Aster Bunnymund, the only emissary of the fabled brotherhood of the Pookas—the league of philosophical warrior rabbits of imposing intellect and size. Highly skilled in martial arts (many of which he invented himself), Bunnymund is brilliant, logical, and a tunnel-digger extraordinaire. If the Guardians need paths near the Earth’s core, he’s their Pooka. He’s also armed with magnificent weapons of an oval-sort, and might just be able to help in the quest for the second piece of the Moonclipper. This second book in The Guardians series is about much more than fixing a few rotten eggs—it brings the Guardians one step closer to defeating Pitch!
