Download or read book Earth s Early Atmosphere and Oceans and The Origin of Life written by George H. Shaw and published by Springer. This book was released on 2015-10-07 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive treatment of the chemical nature of the Earth’s early surface environment and how that led to the origin of life. This includes a detailed discussion of the likely process by which life emerged using as much quantitative information as possible. The emergence of life and the prior surface conditions of the Earth have implications for the evolution of Earth’s surface environment over the following 2-2.5 billion years. The last part of the book discusses how these changes took place and the evidence from the geologic record that supports this particular version of early and evolving conditions.

Download or read book Earth Our Living Planet written by Philippe Bertrand and published by Springer Nature. This book was released on 2021-04-21 with total page 573 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earth is, to our knowledge, the only life-bearing body in the Solar System. This extraordinary characteristic dates back almost 4 billion years. How to explain that Earth is teeming with organisms and that this has lasted for so long? What makes Earth different from its sister planets Mars and Venus? The habitability of a planet is its capacity to allow the emergence of organisms. What astronomical and geological conditions concurred to make Earth habitable 4 billion years ago, and how has it remained habitable since? What have been the respective roles of non-biological and biological characteristics in maintaining the habitability of Earth? This unique book answers the above questions by considering the roles of organisms and ecosystems in the Earth System, which is made of the non-living and living components of the planet. Organisms have progressively occupied all the habitats of the planet, diversifying into countless life forms and developing enormous biomasses over the past 3.6 billion years. In this way, organisms and ecosystems "took over" the Earth System, and thus became major agents in its regulation and global evolution. There was co-evolution of the different components of the Earth System, leading to a number of feedback mechanisms that regulated long-term Earth conditions. For millennia, and especially since the Industrial Revolution nearly 300 years ago, humans have gradually transformed the Earth System. Technological developments combined with the large increase in human population have led, in recent decades, to major changes in the Earth's climate, soils, biodiversity and quality of air and water. After some successes in the 20th century at preventing internationally environmental disasters, human societies are now facing major challenges arising from climate change. Some of these challenges are short-term and others concern the thousand-year evolution of the Earth's climate. Humans should become the stewards of Earth.

Download or read book Atmosphere Earth Science Children s Book With Facts And Pictures written by Bold Kids and published by FASTLANE LLC. This book was released on 2022-03-07 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Did you know that the atmosphere is made up of different layers? In fact, this layer is a huge part of our planet, supporting all life forms. And, you might not know, the atmosphere also plays a vital role in determining the weather! The following facts will help you better understand this fascinating element. But, before you can get started with these fascinating facts, here are a few things you should know about the atmospheric layers.The first layer of the atmosphere is called the troposphere, which is about 500-800 km high. It is a dense environment with a large number of gas molecules and dust pbooks, and can reach temperatures of 1700 degrees Celsius. In fact, the atmosphere's composition changes over the course of millions of years, and there are currently several different layers. Learn about the different layers of our atmosphere and how they influence our daily lives.The atmosphere contains a wide range of gases, but two of them are the most important. Oxygen and nitrogen are the most abundant gases in the atmosphere, while other gases are present in trace amounts. The different layers of the atmosphere have different temperatures and densities, and they play a critical role in keeping our world cool. And remember, there are five different layers to the atmosphere. The thickness and density of the layers vary and affect the way our planet experiences weather.

Download or read book Earth s Atmosphere written by Melissa Raé Shofner and published by The Rosen Publishing Group, Inc. This book was released on 2018-07-15 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earth's atmosphere plays a very important role in sustaining life on the planet. The atmosphere is made of a very thin layer of air, which covers every inch of Earth's surface up to the edge of space. The atmosphere is comprised of different chemicals and compounds at any given location, which also means that the atmosphere behaves in different ways at any given location. This book explores the atmosphere's composition, its behavior, and how it affects life on Earth.
Download or read book The Life and Death of Planet Earth written by Peter D. Ward and published by Macmillan. This book was released on 2003 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Planet Earth is middle-aged. Science has worked hard to piece together the story of the evolution of our world up to this point, but only recently have we developed the understanding and the tools to describe the entire life cycle of a planet. Ward and Brownlee, a geologist and an astronomer respectively, combine their knowledge of how the critical sustaining systems of our planet evolve through time with their understanding of the life cycles of stars and solar systems, to tell the story of the second half of Earth's life. The process of evolution will essentially reverse itself: life as we know it will subside until only the simplest forms remain. Eventually, they too will disappear. The oceans will evaporate, the atmosphere will degrade, and, as the sun slowly expands, Earth itself will eventually meet a fiery end. --From publisher description.
Download or read book Revolutions that Made the Earth written by Tim Lenton and published by OUP Oxford. This book was released on 2013-04-11 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Earth that sustains us today was born out of a few remarkable, near-catastrophic revolutions, started by biological innovations and marked by global environmental consequences. The revolutions have certain features in common, such as an increase in complexity, energy utilization, and information processing by life. This book describes these revolutions, showing the fundamental interdependence of the evolution of life and its non-living environment. We would not exist unless these upheavals had led eventually to 'successful' outcomes - meaning that after each one, at length, a new stable world emerged. The current planet-reshaping activities of our species may be the start of another great Earth system revolution, but there is no guarantee that this one will be successful. The book explains what a successful transition through it might look like, if we are wise enough to steer such a course. This book places humanity in context as part of the Earth system, using a new scientific synthesis to illustrate our debt to the deep past and our potential for the future.
Download or read book The Story of Earth written by Robert M. Hazen and published by Penguin. This book was released on 2013-07-30 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hailed by The New York Times for writing “with wonderful clarity about science . . . that effortlessly teaches as it zips along,” nationally bestselling author Robert M. Hazen offers a radical new approach to Earth history in this intertwined tale of the planet’s living and nonliving spheres. With an astrobiologist’s imagination, a historian’s perspective, and a naturalist’s eye, Hazen calls upon twenty-first-century discoveries that have revolutionized geology and enabled scientists to envision Earth’s many iterations in vivid detail—from the mile-high lava tides of its infancy to the early organisms responsible for more than two-thirds of the mineral varieties beneath our feet. Lucid, controversial, and on the cutting edge of its field, The Story of Earth is popular science of the highest order. "A sweeping rip-roaring yarn of immense scope, from the birth of the elements in the stars to meditations on the future habitability of our world." -Science "A fascinating story." -Bill McKibben
Download or read book Earth As A Cradle For Life The The Origin Evolution And Future Of The Environment written by Frank D Stacey and published by World Scientific. This book was released on 2013-06-21 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Earth as a Cradle for Life aims to fill the gap between readers who have a strong and informed scientific interest in the environment (but no access to the journal literature), and their desire for a basic understanding of the environment. It provides a comprehensive account, and requires no advanced mathematical skills. It will also satisfy a need for a textbook on fundamental science for students in tertiary environmental science courses that may otherwise neglect the underlying basis of their subject.The Earth as a Cradle takes a step back from common perceptions of the environment, and presents a new fundamental perspective. It draws attention to observations that have been neglected or discounted for reasons the authors found invalid, and which allow a more coherent account of the environment than is possible without them.Misunderstandings about the environment are common, even in the scientific community. They arise in part from the multi-disciplinary nature of the subject and the difficulty in keeping all relevant observations in mind and assessing their validity. These misunderstandings are often consequences of the band-wagon effect: when an idea is reinforced by repeated quotation and becomes difficult to contradict even when it is in obvious conflict with observations. This is especially so in a subject with strong media interest and conflicting commercial interests — and Cradle sweeps these considerations aside and presents a new environmental scenario.This book draws on several decades of research by the authors on fundamental Earth science, and presents probing insights on environmental questions that are not widely recognized — even in the professional community. For this reason it will become a landmark in the environmental science and Earth science literature.

Download or read book A Very Short History of Life on Earth written by Henry Gee and published by St. Martin's Press. This book was released on 2021-11-09 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Royal Society's Science Book of the Year "[A]n exuberant romp through evolution, like a modern-day Willy Wonka of genetic space. Gee’s grand tour enthusiastically details the narrative underlying life’s erratic and often whimsical exploration of biological form and function.” —Adrian Woolfson, The Washington Post In the tradition of Richard Dawkins, Bill Bryson, and Simon Winchester—An entertaining and uniquely informed narration of Life's life story. In the beginning, Earth was an inhospitably alien place—in constant chemical flux, covered with churning seas, crafting its landscape through incessant volcanic eruptions. Amid all this tumult and disaster, life began. The earliest living things were no more than membranes stretched across microscopic gaps in rocks, where boiling hot jets of mineral-rich water gushed out from cracks in the ocean floor. Although these membranes were leaky, the environment within them became different from the raging maelstrom beyond. These havens of order slowly refined the generation of energy, using it to form membrane-bound bubbles that were mostly-faithful copies of their parents—a foamy lather of soap-bubble cells standing as tiny clenched fists, defiant against the lifeless world. Life on this planet has continued in much the same way for millennia, adapting to literally every conceivable setback that living organisms could encounter and thriving, from these humblest beginnings to the thrilling and unlikely story of ourselves. In A (Very) Short History of Life on Earth, Henry Gee zips through the last 4.6 billion years with infectious enthusiasm and intellectual rigor. Drawing on the very latest scientific understanding and writing in a clear, accessible style, he tells an enlightening tale of survival and persistence that illuminates the delicate balance within which life has always existed.
Download or read book Earth System Science A Very Short Introduction written by Tim Lenton and published by Oxford University Press. This book was released on 2016-02-25 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.
