This series provides a history of time and our gradual comprehension, measuring and recording of different types of time. This text looks at Earth time. It emphasises science and history with key dates boxes and spreads that act as mini timelines and is suitable for school projects.

The dramatic history of planet Earth and the rocky road to understanding the past A probing account of the history of the earth and an introduction to the many eccentric characters that have attempted to understand its origins. Full of fascinating anecdotes about 19th century explorers and natural philosophers who first carved up Earth's history just as others were carving up the globe. Unravels the fascinating history of rock strata and the implications they have had on accepted theories on the Earth's life. Considers the future of the earth, and what a repeat of some of the catastrophic events of the earth's past, such as major earthquakes and asteroid collisions, could mean for life today.

Even in the age of high-tech our bodies still respond to the cycles of earth and moon. This handbook demonstrates how we can rediscover the sacredness of everyday experiences and reconnect with the rhythm of the natural world. It also covers how the energies of your birth moon affect your life.

The Third Doctor and Jo Grant arrive for a well-deserved holiday of sun and ‘blokarting’ on a salt lake in Australia in 2028. Weird sculptures adorn the landscape – statues carved from the salt. People have been leaving them in the salt lakes for years – but these look different. Grotesque, distorted figures twisted in pain. They don’t last long in the rain and the wind, but they’re just made of salt... Aren’t they?

This best-selling historical geology text provides geologists with an excellent balance of basic geology and paleontology. The ninth edition presents rich, authoritative coverage of the history of the Earth, offering the most comprehensive history in the discipline today. It maintains its strong approach to stratigraphy and paleontology that other texts have lost. The text's paleogeographic maps are excellent in detail and are a vital component in understanding the earth's history. Stunning artwork brings the ancient world to life. Geology of National Parks boxes encourage them to visit these parks to appreciate their geological significance. Geologists will also appreciate the questions about past geologic events and the processes used in finding answers.

Are we going too fast to stop? Is there another way? In this new collection of essays David Suzuki points the way to a slower way of life in tune with the Earth and its riches.As we rush towards the end of the millennium, we find ourselves in a time of unprecedented change and growth -- in population, in consumerism, in pollution, in information exchange. Are these changes happening too fast? Is it too late to stop and assess? In these essays, David Suzuki takes stock and points the way to a brighter future and a world that we can proudly leave to our children and grandchildren. He looks unflinchingly at the forces that have driven us to the edge: globalization, political shortsightedness, greed, and willful blindness. And he looks at the places from which we should take strength and hope: nature, nurturing of the Earth, local initiatives, children.

In the twenty-first century, we take the means to measure time for granted, without contemplating the sophisticated concepts on which our time scales are based. This volume presents the evolution of concepts of time and methods of time keeping up to the present day. It outlines the progression of time based on sundials, water clocks, and the Earth's rotation, to time measurement using pendulum clocks, quartz crystal clocks, and atomic frequency standards. Time scales created as a result of these improvements in technology and the development of general and special relativity are explained. This second edition has been updated throughout to describe twentieth- and twenty-first-century advances and discusses the redefinition of SI units and the future of UTC. A new chapter on time and cosmology has been added. This broad-ranging reference benefits a diverse readership, including historians, scientists, engineers, educators, and it is accessible to general readers.

This volume presents the latest science on all significant geological and paleontological aspects of the Earth during the Late Triassic Period. Rather than presenting a collection of narrowly focused research papers, the volume consists of a series of peer-reviewed chapters on specific aspects of the Late Triassic world (e.g., tectonics, magmatism, paleobotany, climate, etc.), all authored by experts in the subject of their respective chapters. Each chapter reviews and summarizes the latest findings in these fields and also includes a review of the pertinent literature. The author list is very broadly international and forms a veritable who’s who of expertise in these fields. The book is loosely organized to present the physical aspects of Earth during the Late Triassic at the outset, followed by the paleontological aspects. The latter section is further organized to present the record of the marine environment first before moving onto land, with fauna followed by flora. The volume closes with a review of the end-Triassic extinctions.
