Tectonic activity around the Pacific plate, for instance, creates the Ring of Fire. This tectonically active area includes volcanoes such as Mount Fuji, Japan, and earthquake-prone fault zones such as the west coast of the United States. A peerless A–Z guide to the names, places and events in the world of J.R.R. Tolkien, fully illustrated in colour throughout by acclaimed Tolkien artist, Ted Nasmith. Jupiter, Saturn, Uranus, and Neptune all have atmospheres made mostly of hydrogen and helium. These planets are called gas giants, because they are mostly made of gas and do not have a solid outer crust.

Fascinating, gorgeously illustrated and thought-provoking. . . . [A] masterful book."—Elizabeth Hand, Washington Post The Mesozoic era began about 251 million years ago. This was the era when dinosaurs flourished. The Mezozoic has three periods: the Triassic, the Jurassic, and the Cretaceous. Much like fantasy maps, these maps can be used as a foundation for other things. These maps have since been used to test the state of the tide into the future to understand if the present day does have abnormally strong tides.The Worlds of J. R. R. Tolkien] is beautifully designed and produced . . . It’s a magical book, one is both intricately researched and filled with gems of wonder."—Lorena Carrington, The Bone Lantern A fascinating, gorgeously illustrated and thought-provoking examination of the landscapes, cities and architecture that inspired Tolkien during his lifelong creation of Middle-earth. . . . Garth, a journalist as well as a Tolkien scholar, proves an exceptional guide to Middle-earth . . . [A] masterful book."—Elizabeth Hand, Washington Post The Complete Guide to Middle-earth has been compiled to enhance the reader’s enjoyment of Tolkien’s books by bringing together in an A-Z sequence all the key facts and information about names, places, languages and events from The Hobbit, The Lord of the Rings and The Silmarillion. Ice sheets and glaciers melt, transforming into liquid water. The most abundant liquid water on the planet is in the ocean, although lakes, rivers, and underground aquifers also hold liquid water. Life on Earth is dependent on a supply of liquid water. Most organisms, in fact, are made up mostly of liquid water, called body water. The human body is about 50 percent to 60 percent body water. In addition to survival and hygiene, people use liquid water for energy and transportation. All living or once-living materials contain carbon. These materials are organic. Plants and other autotrophs depend on carbon dioxide to create nutrients in a process called photosynthesis. These nutrients contain carbon. Animals and other organisms that consume autotrophs obtain carbon. Fossil fuels, the remains of ancient plants and animals, contain very high amounts of carbon.

Tolkien scholar Garth, with the cooperation of the author’s estate, introduces fellow Middle-earth fans to the locales, in Britain and throughout the world, that inspired settings in the Lord of the Rings trilogy and other Tolkien titles."— Publishers WeeklyLet’s begin with a question. Are the tides always the same on every planet? Because of the force of gravity, and interaction between planetary bodies, we know every planet will have tides in some form. However, because every planet is different, the tides cannot be the same everywhere. We know from calculations that they are not; the tide is observably unique on every planet in the solar system. Therefore, by that logic, the tide should be different on every planet in the universe. The first, and definitive, encyclopedia, The Complete Guide to Middle-earth is now available for the first time as a clothbound deluxe edition, housed in a fully illustrated slipcase, to complement the deluxe illustrated editions of The Silmarillion and Unfinished Tales, and is lavishly illustrated with more than 50 full-colour paintings by acclaimed Tolkien artist, Ted Nasmith, with many appearing exclusively in this edition. The hydrosphere is composed of all the water on Earth. Nearly three-fourths of Earth is covered in water, most of it in the ocean. Less than three percent of the hydrosphere is made up of freshwater. Most freshwater is frozen in ice sheets and glaciers in Antarctica, the North American island of Greenland, and the Arctic. Freshwater can also be found underground, in chambers called aquifers, as well as rivers, lakes, and springs.
