"Earth Science: An Illustrated Guide to Science" is one of eight volumes of "Facts On File's" new "Science Visual Resources" set. Containing six sections, a comprehensive glossary, a Web site guide, and an index, Biology is an ideal learning tool for students and teachers of science. Full-colour diagrams, graphs, charts, and maps on every page illustrate the essential elements of the subject, while parallel text provides key definitions and step-by-step explanations. The six sections include: "Planet Earth" - considers Earth's place in the Solar System and its relationship to the Sun, the Moon, and the environment of interplanetary space.

More than 3,700 updated and expanded, cross-referenced entries, more than 300 of which are new, cover all aspects of Earth science: geomorphology, stratigraphy, mineralogy, petrology, climatology, oceanography, paleontology, hydrology, geophysics, cartography, surveying, and soil science. Key concepts in physics, chemistry, biology, and mathematics are also defined. Tables at the back of the book include Earth measurements, chemical elements, composition of seawater and the atmosphere, elements in the Earth's crust, meteorological symbols, glacial periods, and more. Topics covered include: Absorption; Earthquake intensity; Hydrology; Lava tube; Nutrients; Radiocarbon dating; Saffir-Simpson Hurricane Scale; and, Weather station.
from the Introduction: Have you ever seen pictures of astronauts floating in space? Have you ever wondered why we do not float off the earth? When you push open a door, you are using a force. Forces are pushes or pulls. Forces make objects move. One force, called gravity, always pulls us toward earth. It keeps us from floating off into space. Even astronauts floating in a space shuttle are being pulled toward earth by gravity. They are floating because the spaceship is also being pulled toward earth. Gravity makes us and every object fall toward earth when dropped. We measure the force of gravity by weighing objects. You can find your weight by standing on a bathroom scale. Gravity pulls you down against the scale. Your weight is the force gravity exerts on you. Weight is measured in pounds (lb) or kilograms (kg). Pounds are divided into ounces (oz). Kilograms are divided into grams (g). The weights of small things, like medicines, are measured in ounces or grams. In this book, you will learn how to change one kind of measurement, like kilograms, into another such as pounds.
The following poem was presented at the memorial service for Van Rensselaer Potter, author of this book, held on November 7, 2001. It was writen by his grandson, Josh Simon. To Save the Earth Save the Earth We must First Love Respecting Life and each other now in the Present We Exist for the Future generations of Humanity We must care We shall Live on this Earth We Should Survive
