The importance of the oceans to life on Earth cannot be overstated. Liquid water covers more than 70% of our planet's surface and, in past geological time, has spread over 85%. Life on Earth began in the oceans over 3.5 billion years ago and remained there for the great majority of that time. Today the seas still provide 99% of habitable living space, the largest repository of biomass, and holds the greatest number of undiscovered species on the planet. Our oceans are vital for the regulation of climate, and with global warming and decreasing land area, they have become increasingly important as the source of food, energy in the form of oil and gas, and for their mineral wealth. Oceans also form a key part of the biogeochemical cycles of carbon, nitrogen, and other elements critical to life. Nutrients in upwelling areas are spread by ocean currents, and the plankton of the seas supports a wealth of wildlife. In this Very Short Introduction Dorrik Stow analyses these most important components of our blue planet and considers their relationship with, and exploitation by, humans. He shows how the oceans are an essential resource to our overpopulated world, and discusses why exploration and greater scientific understanding of the oceans, their chemistry, and their mineral wealth are now a high priority. Stow also explores what we know of how oceans originate, and evolve and change; the shape of the seafloor and nature of its cover; the physical processes that stir the waters and mix such a rich chemical broth; and the inseparable link between oceans and climate. As polar ice melts and sea-levels rise, countless millions who have made their homes on low-lying lands close to the sea are threatened. As scientific exploration of the seas gathers pace, the new knowledge gained of the ocean-Earth systems and their interaction with the human environment is vital to our understanding of how we can preserve these ultimately fragile environments.

The atmosphere is the thin, diffuse fluid that envelops the Earth's surface. Despite its apparent fragility, the existence of this fluid is vital for human and other life on Earth. In this Very Short Introduction Paul Palmer describes the physical and chemical characteristics of different layers in the atmosphere, and shows how the interactions where the atmosphere is in contact with land, ocean, and ice affect its observed physical and chemical properties. He also looks at how movement in the atmosphere, driven by heat from the sun, transports heat from lower latitudes to higher latitudes, and is a fundamental feature of the general circulation in the atmosphere. Finally, Palmer presents an overview of the types of measurements used to understand different parts of the atmosphere, and identifies the future challenges for atmospheric scientists.

For generations, the ground beneath the feet of our ancestors seemed solid and unchanging. Around 30 years ago, two things happened that were to revolutionize the understanding of our home planet. First, geologists realized that the continents themselves were drifting across the surface of the globe and that oceans were being created and destroyed. Secondly, pictures of the entire planet were returned from space. As the astronomer Fred Hoyle had predicted, this 'let loose an idea as powerful as any in history'. Suddenly, the Earth began to be viewed as a single entity; a dynamic, interacting whole, controlled by complex processes we scarcely understood. It began to seem less solid. As one astronaut put it, 'a blue jewel on black velvet; small, fragile and touchingly alone'. Geologists at last were able to see the whole as well as the detail; the wood as well as the trees. This book brings their account up to date with the latest understanding of the processes that govern our planet.

The 1960s revealed a new and revolutionary idea in geological thought: that the continents drift with respect to one another. After having been dismissed for decades as absurd, the concept gradually became part of geology's basic principles. We now know that the Earth's crust and upper mantle consist of a small number of rigid plates that move, and there are significant boundaries between pairs of plates, usually known as earthquake belts. Plate tectonics now explains much of the structure and phenomena we see today: how oceans form, widen, and disappear; why earthquakes and volcanoes are found in distinct zones which follow plate boundaries; how the great mountain ranges of the world were built. The impact of plate tectonics is studied closely as these processes continue: the Himalaya continues to grow, the Atlantic is widening, and new oceans are forming. In this Very Short Introduction Peter Molnar provides a succinct and authoritative account of the nature and mechanisms of plate tectonics and its impact on our understanding of Earth.

Der Wandel eines faszinierenden, bedrohten Lebensraums Die Ozeane sind nicht nur der größte Lebensraum der Erde, sondern auch der am wenigsten erforschte. Die unermessliche Vielfalt dieses Ökosystems beginnen wir erst jetzt bis in die letzten Winkel zu begreifen – auch wie wichtig das Meer für unser Leben ist. Im letzten Jahrhundert hat jedoch die Herrschaft des Menschen über die Natur auch die Ozeane erreicht: Wir fischen die Meere leer und füllen sie stattdessen mit Umweltgiften. Tiefseebergbau droht den Lebensraum unzähliger Pflanzen und Tiere bis zur Unkenntlichkeit zu verändern. Die Klimaerwärmung ließ bereits ein Viertel aller Korallen zugrunde gehen. In seinem aufrüttelnden Buch beschreibt der Meeresbiologe und –schützer Callum Roberts den großen Reichtum der Ozeane und ihren Wandel, und er ruft dazu auf, der Zerstörung der Meere endlich Einhalt zu gebieten, denn noch ist es nicht zu spät.

When humanity first glimpsed planet Earth from space, the unity of the system that supports humankind entered the popular consciousness. The concept of the Earth's atmosphere, biosphere, oceans, soil, and rocks operating as a closely interacting system has rapidly gained ground in science. This new field, involving geographers, geologists, biologists, oceanographers, and atmospheric physicists, is known as Earth System Science. In this Very Short Introduction, Tim Lenton considers how a world in which humans could evolve was created; how, as a species, we are now reshaping that world; and what a sustainable future for humanity within the Earth System might look like. Drawing on elements of geology, biology, chemistry, physics, and mathematics, Lenton asks whether Earth System Science can help guide us onto a sustainable course before we alter the Earth system to the point where we destroy ourselves and our current civilisation.

Bacteria form a fundamental branch of life. They are the oldest forms of life as we know it, and they are still the most prolific living organisms. They inhabit every part of the Earth's surface, its ocean depths, and even terrains such as boiling hot springs. They are most familiar as agents of disease, but benign bacteria are critical to the recycling of elements and all ecology, as well as to human health. In this Very Short Introduction, Sebastian Amyes explores the nature of bacteria, their origin and evolution, bacteria in the environment, and bacteria and disease. In looking at our efforts to manage co-evolving bacteria, he also considers the challenges of resistance to antibiotics.

Deserts make up a third of the planet's land surface, but if you picture a desert, what comes to mind? A wasteland? A drought? A place devoid of all life forms? Deserts are remarkable places. Typified by drought and extremes of temperature, they can be harsh and hostile; but many deserts are also spectacularly beautiful, and on occasion teem with life. Nick Middleton explores how each desert is unique: through fantastic life forms, extraordinary scenery, and ingenious human adaptations. He demonstrates a desert's immense natural beauty, its rich biodiversity, and uncovers a long history of successful human occupation. This Very Short Introduction tells you everything you ever wanted to know about these extraordinary places and captures their importance in the working of our planet.

The three centuries which followed the conquests of Alexander are perhaps the most thrilling of all periods of ancient history. This was an age of cultural globalization: in the third century BC, a single language carried you from the Rhône to the Indus. A Celt from the lower Danube could serve in the mercenary army of a Macedonian king ruling in Egypt, and a Greek philosopher from Cyprus could compare the religions of the Brahmins and the Jews on the basis of first-hand knowledge of both. Kings from Sicily to Tajikistan struggled to meet the challenges of ruling multi-ethnic states, and Greek city-states came together under the earliest federal governments known to history. The scientists of Ptolemaic Alexandria measured the circumference of the earth, while pioneering Greek argonauts explored the Indian Ocean and the Atlantic coast of Africa. Drawing on inscriptions, papyri, coinage, poetry, art, and archaeology, in this Very Short Introduction Peter Thonemann opens up the history and culture of the vast Hellenistic world, from the death of Alexander the Great (323 BC) to the Roman conquest of the Ptolemaic kingdom (30 BC).

Who were the Druids? What do we know about them? Do they still exist today? The Druids first came into focus in Western Europe - Gaul, Britain, and Ireland - in the second century BC. They are a popular subject; they have been known and discussed for over 2,000 years and few figures flit so elusively through history. They are enigmatic and puzzling, partly because of the lack of knowledge about them has resulted in a wide spectrum of interpretations. Barry Cunliffe takes the reader through the evidence relating to the Druids, trying to decide what can be said and what can't be said about them. He examines why the nature of the druid caste changed quite dramatically over time, and how successive generations have interpreted the phenomenon in very different ways.

Rocks, more than anything else, underpin our lives. They make up the solid structure of the Earth and of other rocky planets, and are present at the cores of gas giant planets. We live on the rocky surface of the planet, grow our food on weathered debris derived from rocks, and we obtain nearly all of the raw materials with which we found our civilization from rocks. From the Earth's crust to building bricks, rocks contain our sense of planetary history, and are a guide to our future. In this Very Short Introduction Jan Zalsiewicz looks at the nature and variety of rocks, and the processes by which they are formed. Starting from the origin of rocks and their key role in the formation of the Earth, he considers what we know about the deep rocks of the mantle and core, and what rocks can tell us about the evolution of the Earth, and looks at those found in outer space and on other planets.

Minerals existed long before any forms of life, playing a key role in the origin and evolution of life; an interaction with biological systems that we are only now beginning to understand. Exploring the traditional strand of mineralogy, which emphasises the important mineral families, the well-established analytical methods (optical microscopy and X-ray diffraction) and the dramatic developments made in techniques over recent decades, David Vaughan also introduces the modern strand of mineralogy, which explores the role minerals play in the plate tectonic cycle and how they interact with the living world. Demonstrating how minerals can be critical for human health and illness by providing essential nutrients and releasing poisons, Vaughan explores the multitude of ways in which minerals have aided our understanding of the world.
