Illustrated Encyclopedia of the Earth

Product Information

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.

Each journey around the sun, a trip of about 940 million kilometers (584 million miles), is called a revolution. A year on Earth is the time it takes to complete one revolution, about 365.25 days. Earth orbits the sun at a speedy rate of about 30 kilometers per second (18.5 miles per second). This marvelous book draws on Garth's substantial research, his perceptive observations about how Tolkien responded to places and changed them for his own purposes, and insights by other Tolkien specialists. Wonderfully supported by a gallery of illustrations, The Worlds of J. R. R. Tolkien is a fine achievement."—Kevin Crossley-Holland, author of The Norse Myths So, with all that in mind, how could we test these processes on other planets? We employed worldbuilding in two methods to help understand the role of topography (tectonics) in affecting the tidal state of a planet.

Earth is the planet we live on, one of eight planets in our solar system and the only known place in the universe to support life.

The part of Earth facing the sun is in daylight; the part facing away from the sun is in darkness. If Earth did not rotate, one-half of Earth would always be too hot to support life, and the other half would be frozen. Earth rotates from west to east, so the sun appears to rise in the east and set in the west. John Garth’s beautifully illustrated volume, The Worlds of J. R. R. Tolkien, reconstructs and theorizes Tolkien’s earthly sources for Middle-earth. He leaves breadcrumbs for scholars of all stripes. Whether your curiosities lie in Switzerland or South Africa, in the Aeneid or The Great Wave off Kanagawa, something is bound to reel you in."—Bécquer Seguín, Public Books 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.Earth’s physical environment is often described in terms of spheres: the magnetosphere, the atmosphere, the hydrosphere, and the lithosphere. Parts of these spheres make up the biosphere, the area of Earth where life exists. The charged particles that int eract with Earth’s magnetosphere are called the solar wind. The pressure of the solar wind compresses the magnetosphere on the “dayside” of Earth to about 10 Earth radii. The long tail of the magnetosphere on the “nightside” of Earth stretches to hundreds of Earth radii. The most well-known aspect of the magnetosphere are the charged particles that sometimes interact over its poles—the auroras, or Northern and Southern Lights. 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. Earth is the third planet from the sun, after Mercury and Venus, and before Mars. It is about 150 million kilometers (about 93 million miles) from the sun. This distance, called an astronomical unit (AU), is a standard unit of measurement in astronomy. Earth is one AU from the sun. The planet Jupiter is about 5.2 AU from the sun—about 778 million kilometers (483.5 million miles).

Garth identifies the locales that served as the basis for Hobbiton, the elven valley of Rivendell, the Glittering Caves of Helm’s Deep, and many other settings in Middle-earth, from mountains and forests to rivers, lakes, and shorelands. He reveals the rich interplay between Tolkien’s personal travels, his wide reading, and his deep scholarship as an Oxford don. Garth draws on his profound knowledge of Tolkien’s life and work to shed light on the extraordinary processes of invention behind Tolkien’s works of fantasy. He also debunks popular misconceptions about the inspirations for Middle-earth and puts forward strong new claims of his own. The hydrosphere helps regulate Earth’s temperature and climate. The ocean absorbs heat from the sun and interacts with the atmosphere to move it around Earth in air currents.planet earth illustration surrounded by hands, Earth Overshoot Day Earth Day, Earth, globe, hand, recycling png 800x800px 806.28KB Earth’s atmosphere is a blanket of gases enveloping Earth and retained by our planet’s gravity.

The white lines are called co-tidal lines, they meet up at points on the Earth where there is “no tide” or no change in the surface of the ocean due to the M2 tide. The arrows around them show the direction the tide moves about the point (Image credit NASA).
