Uses trilobite fossils as an example to illustrate the challenges scientists face in understanding the prehistoric world and its place in time. Examines fossil sites in Australia, discusses how fossils are formed, and tells how a fossil's world is recreated.
While asleep, a young girl dreams that her computer teaches her about earth's geographic areas. Uses a globe to tell about areas of water (oceans, lakes, and rivers), land (mountains, forests, canyons, deserts, plains, and poles), and climates (cold, tropic, and moderate). Emphasizes that all areas and features of earth support life.
Do the continents move? In this segment, students learn the relationship between a molten core, plate tectonics, and continental drift. Part of the "Earth Science" series.
Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, intrigued by the name given to the mountains, "the hills of the round earth," Moko sets off to find out if the earth is really round. An old man tells him if he keeps walking straight, he could travel round the earth and get back to his starting point. Moko follows his advice but since he never got the feeling he was walking around a sphere, he still thinks the earth is flat.
What causes day and night? Why do we have seasons? Through easy-to-understand animations, as well as live-action video footage, these difficult concepts are easily explained. The rotation of Earth on its axis, and its revolution around the sun are the focus of this video. Colorful graphics illustrate the movement of our planet throughout the course of a year. Important terminology includes: axis, tilt, rotation, revolution, orbit, season, solstice, and equinox.
The planets closest to the sun, often referred to as the inner planets, are the focus of this program. Colorful animations, along with images captured by space probes, illustrate the characteristics of Mercury, Venus, Earth, and Mars. The fundamental structure of the solar system and the process by which planets revolve around the sun are discussed. Special attention is given to the features that make Earth unique in the solar system. Important terminology includes: sun, orbit, revolve, gravity, inertia, rotation, axis, atmosphere, and spacecraft.
Gravity and erosion are major factors in changing the shape of the surface of Earth. The different types of erosion and the effect of gravity on objects is discussed in this video. Other topics covered include folding, faulting, deposition, creep, mass movement, landslide, surface runoff, alluvial fan, delta, stream erosion, beach erosion, ice erosion, wind erosion, dune, glaciers, and glacial deposits.
This segment investigates the geosphere and its components, including plate tectonics, surface processes, and the rock cycle. It also discusses how geoscientists collect evidence to study past, present, and future changes by using computer-based technologies that model and monitor Earth’s systems and processes. Part of the "Visions of Earth" series.
Developed by the American Geosciences Institute, this segment provides an essential and well-tested tool for teaching and learning about the planet. Eight different scientists describe their field work and geoscience research. Part of the "Visions of Earth" series.
Part of a series that features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. Begins with a simple definition of the term and concludes with a critical thinking question. For this particular video, students will focus on the term earth. Part of the Science Video Vocab Series.
Take a high performance ride through the formation of the third planet from the Sun. Learn how Earth was created and discover what creatures hold clues to how life began. What evil forces threaten the demise of Earth? Complex and controversial, this is the scientific detective story of all time. Cutting-edge graphics are used along with the stories of scientists and explorers who dare to venture into the uncharted territory of the cosmos.
Drawing upon the American Geological Institute's huge geoscientific archive of information, this segment explores the hydrosphere and the atmosphere. It also covers their formation and components, the water cycle, geological evidence of past climate change, extreme weather, and the future of the fluid spheres. Part of the "Visions of Earth" series.
Spin plays a key role in controlling the planet. It drives the day and night cycle and controls the weather and climate. This episode explores how the spin of Earth sets the rhythm of life on planet Earth. Part of the "Orbit: Earth's Extraordinary Journey" series.
As shown on the History Channel. Why do we have ice ages and when is the next one due? Chart the progress of different ice ages through the history of our planet, from Snowball Earth hundreds of millions of years ago to the recent ice ages. As the Earth circles the sun, its orbit changes slightly and so does it angle of rotation. When the right wobble in our rotation combines with the right orbit, the Earth is, and will again be, plunged into an ice age--but maybe not for a few thousand years.
Host Peter Tonge visits with Wayne Schoech of New England Bonsai Gardens who offers suggestions on how to care for bonsai (ancient Oriental art form of miniaturizing trees and shrubs) when you bring it home. Mark Heinlein, also from the Gardens, transforms a three-year-old juniper into an ancient, windswept tree in 25 minutes. Originally aired as an episode of "The Good Green Earth."
How does NASA spot asteroids that maybe getting too close to Earth for comfort? It takes a lot of data gathering by computers, satellites, and individuals. Asteroids are tracked and monitored frequently by astronomers.
As shown on the History Channel. From Alaska to New Mexico, the Rockies are one of the great mountain belts of the world--caused by tectonic forces of the Pacific Plate pushing against the North American continent. They have formed as the earth's continental crust has been shortened under pressure, by around one inch a year. What's more, they are still rising and they are still young in geologic terms: when the dinosaurs roamed the Earth they had not even started to form.
As shown on the History Channel. The Sierra Nevada, North America's highest mountain range, contains one of the most awe-inspiring geological features on the planet: Yosemite Valley. Walled by sheer 3,000-foot granite cliffs and made from one of the toughest rocks on earth, it is home to the mighty El Capitan and iconic Half Dome. Yet how this extraordinary valley formed has been the subject of controversy for over 100 years. Was it carved by gigantic glaciers or a cataclysmic rifting of the Earth?
Produced by the American Geosciences Institute, this segment provides an overview of the biosphere and its components. Additional discussions include how humans are impacting the biosphere. Part of the "Visions of Earth" series.
