Protection at a Price follows the shifts in Aboriginal protection policy, and the price Aboriginal people had to pay for that protection, in almost seventy years of Commonwealth administration of the Northern Territory. It begins with the Aboriginals Ordinance 1911 when Aboriginal people were believed by many to be dying out, and ends with the Land Rights (Northern Territory) Act (Clth) 1974, not long before Territory self-government, when Aboriginal people were a vibrant part of the Terri...

This introductory text explains the fundamentals of the chemistry of the natural environment and the effects of mankind's activities on the earth's chemical systems.Retains an emphasis on describing how natural geochemical processes operate over a variety of scales in time and space, and how the effects of human perturbation can be measured.Topics range from familiar global issues such as atmospheric pollution and its effect on global warming and oz...

A classic introduction to the story of Earth's origin and evolution—revised and expanded for the twenty-first centurySince its first publication more than twenty-five years ago, How to Build a Habitable Planet has established a legendary reputation as an accessible yet scientifically impeccable introduction to the origin and evolution of Earth, from the Big Bang through the rise of human civilization. This classic account of how our habitable planet was as...

The remarkable scientific story of how Earth became an oxygenated planetThe air we breathe is twenty-one percent oxygen, an amount higher than on any other known world. While we may take our air for granted, Earth was not always an oxygenated planet. How did it come to be this way? Donald Canfield covers this vast history, emphasizing its relationship to the evolution of life and the evolving chemistry of Earth. He guides readers through the various lines of scient...

You may be asking "why does a primary teacher like me need to know anything about science? Is there any chance of my enjoying this book if I am not a scientific nerd?" Fair questions. Here are the answers. Our general aim in writing this textbook material was to provide some basic knowledge about how science works. After all, we live in a very science-oriented and techno world, and it would be nice, surely, to understand a bit about how it all works. We are also wanting...

This modern climatology textbook explains those climates formed near the ground in terms of the cycling of energy and mass through systems.

A must-have introduction to this fundamental driver of the climate systemThe Global Carbon Cycle is a short introduction to this essential geochemical driver of the Earth's climate system, written by one of the world's leading climate-science experts. In this one-of-a-kind primer, David Archer engages readers in clear and simple terms about the many ways the global carbon cycle is woven into our climate system. He begins with a concise overview of the subj...

The new revised edition of a classic Earth science textThis newly revised edition of Global Environment discusses the major elements of the geochemical cycles and global fluxes found in the atmosphere, land, lakes, rivers, biota, and oceans, as well as the human effects on these fluxes. Retaining the strengths of the original edition while incorporating the latest discoveries, this textbook takes an integrated, multidisciplinary, and global approach to geo...

How does life on our planet respond to--and shape--climate? This question has never been more urgent than it is today, when humans are faced with the daunting task of guiding adaptation to an inexorably changing climate. This concise, accessible, and authoritative book provides an unmatched introduction to the most reliable current knowledge about the complex relationship between living things and climate.Using an Earth System framework, David Schimel describes how organisms, commu...

The book is designed to provide you with dictionaries of terms in chemistry to make science simpler for you. The terms have been arranged alphabetically for quick reference. Suitable explanations of terms that have come into public domain recently also find mention. The standard of explanation has been kept at a level of understanding expected from an average secondary and senior secondary student. Illustrations and examples, at appropriate places, have been given. Readers who have not mad...

In 1936 a German chemist identified certain organic molecules that he had extracted from ancient rocks and oils as the fossil remains of chlorophyll--presumably from plants that had lived and died millions of years in the past. It was another twenty-five years before this insight was developed and the term "biomarker" coined to describe fossil molecules whose molecular structures could reveal the presence of otherwise elusive organisms and processes. Echoes of Life is the story of...
