Using a case study approach and employing dramatic video
footage, Earth Revealed: Introductory Geology offers a highly effective program
for students seeking to understand the unfolding of geologic processes over
time and their impact on human life today. Produced with support from the
Annenberg/CPB Project, the series is comprised of 26 half-hour telecourse
episodes that document evidence of geologic principles at geographically
diverse sites -- from the Novarupta Volcano in
(27 minutes each-two per tape):
#1 Down to Earth -- Down to Earth introduces students to the vast field of geology, using striking visuals to help students begin to appreciate the wonders of Earth:.
Surface conditions of the planets Venus and Mars are compared with those of Earth, and scenes of Earth's living landscapes lead into a discussion of how unique Earth truly is. Major topics addressed in the series, including plate tectonics, natural resources, seismology, and erosion, are introduced in this program.
#1 Student Questions #1 Notes
#2 The Restless Planet -- The Restless Planet revisits the beginnings of our solar system and the evolving Earth:
Early Greek astronomers
believed that Earth was the center of the universe. However, this notion
changed dramatically over time, especially after the invention of the telescope.
This program traces the development of astronomical theory with discussions of
the discoveries of Copernicus, Galileo, Kepler, and
#3 Earth's Interior -- Earth's Interior demonstrates how seismic waves occur and explains the measurement of gravity, heat flow, and earth magnetism, to provide information about Earth's interior
Oil wells do more than just produce oil — they serve as windows to Earth’s interior. This program introduces the topic of geophysics, exploring methods of studying what lies beneath Earth’s surface. Geophysicists use seismic wave studies, variations in temperature, magnetic fields, gravity, and computer simulations to create models of deep structures.
#4 The Sea Floor -- The Sea Floor examines major sea-floor features: the mid-oceanic ridge, oceanic trenches and fracture zones.
The mysteries of the ocean floor lie hidden under enormous pressure and total darkness. This program looks at the research submersibles and indirect methods used to study the bottom of the sea, providing a glimpse of volcanic activity, formations such as the continental shelf and mid-ocean ridges, and life forms that thrive at extreme depths.
#5 The Birth of a Theory -- The Birth of a Theory traces origins of the ideas of continental drift and sea-floor spreading, and their contributions to the plate tectonics theory.
In the 1960s, earth scientists developed the theory of plate tectonics. This program traces the development of plate tectonics, beginning with the contributions and methods of geologist Alfred Wegener. Sea-floor spreading, continental drift, paleomagnetism, and the primordial supercontinent Pangaea are some of the topics covered.
#6 Plate Dynamics -- Plate Dynamics introduces theory and concepts about the movements of Earth's plates
program examines the movement and interaction of tectonic plates, which account
for a vast array of geologic formations and phenomena — from
This program erodes the myth of the mountain as a solid, permanent structure. Animations are used to illustrate the process of orogeny (mountain building) through accretion and erosion, as well as the role of plate tectonics, the rock cycle, and how different types of rock are formed in the course of mountain building.
#8 Earth's Structures -- Earth's Structures illustrates how bedrock responds to tectonic forces originating within Earth
A visit to the
#9 Earthquakes -- Earthquakes explores the nature and consequences of earthquakes, the factors that cause quakes, their location and characteristics.
Showing actual footage of earthquakes and their aftermath, this program discusses the forces that fuel these massive events. Faults, waves, and the transfer of energy from the epicenter are explained, and histories of the seismograph and Richter scale are presented. The program also describes devices being developed to study — and eventually predict — earthquakes.
#10 Geologic Time -- Geologic Time helps students develop a sense of the vast amounts of time over which logic processes have been at work.
To illustrate the immensity of geologic time, the entire span of Earth’s existence is compressed down to a year. The timeline of major geologic events is superimposed onto the year for a condensed view of Earth’s evolution. A relationship between this timeline and that of life on Earth is established, with fossils and radiocarbon dating playing a major role in the discovery.
#11 Evolution Through Time -- Evolution Through Time chronicles the development of life on Earth.
The fossil record reveals much about the diversity and development of species. This program examines the traces left by early plants, animals, and single-celled organisms and follows the progression of life forms over time. Connections are drawn between atmospheric gases, climate change, rock formation, biological functions, and mass extinctions.
#12 Minerals: The Materials of Earth -- Minerals: The Materials of the Earth covers the origins, classifications and uses of minerals.
Minerals have been indispensable to human civilization.

#13 Volcanism -- Volcanism explains how volcanoes are formed, and assesses the importance of volcanic activity to Earth's geology and climate. View This Episode.
Volcanoes provide clues
about what is going on inside Earth. Animations illustrate volcanic processes
and how plate boundaries are related to volcanism. The program also surveys the
various types of eruptions, craters, cones and vents, lava domes, magma, and
volcanic rock. The 1980 eruption of
#14 Intrusive Igneous Rocks -- Intrusive Igneous Rocks unveils the rock-forming processes of magmas that do not reach Earth's surface but solidify underground.
Most magma does not extrude onto Earth’s surface but cools slowly deep inside Earth. This magma seeps into crevices in existing rock to form intrusive igneous rocks. Experts provide a graphic illustration of this process and explain the types and textures of rocks such as granite, obsidian, and quartz. Once again, plate tectonics is shown to be involved in the process.
#15 Weathering and Soils -- Weathering and Soils demonstrates how minerals and rocks change when subjected to the physical and chemical conditions that exist at Earth's surface.
The Cleopatra’s Needle obelisk in New York City’s Central Park is severely weathered after only 75 years, whereas the dry climate of Egypt has preserved similar structures in that country for millennia. This program shows how weather, climate, chemicals, temperature, and type of substrate factor into rock and soil erosion. Environmental connections are also considered.
#16 Mass Wasting -- Mass Wasting examines the causes, types and effects of mass wasting.
Anyone undertaking a building project must understand mass wasting — the downslope movement of earth under the influence of gravity. Various factors in mass wasting, including the rock’s effective strength and pore spaces, are discussed, as are different types of mass wasting such as creep, slump, and landslides. Images of an actual landslide illustrate the phenomenon
#17 Sedimentary Rocks: The Key to Past Environments -- Sedimentary Rocks: The Key
to Past Environments illustrates the importance of sedimentary rocks in understanding
This program returns to the
#18 Metamorphic Rocks -- Metamorphic Rocks interprets the causative factors of
metamorphism and the kinds of rocks produced.
The weight of a mountain creates enough pressure to recrystallize rock, thus creating metamorphic rocks. This program outlines the recrystallization process and the types of rock it can create — from claystone and slate to schist and garnet-bearing gneiss. The relationship of metamorphic rock to plate tectonics is also covered.
#19 Running Water I: Rivers, Erosion and Deposition -- Running Water I: Rivers, Erosion and Deposition analyzes the role of running water in sculpting Earth's surface, discusses tectonic and hydrologic cycles and how they work together to shape the land.
Rivers are the most common land feature on Earth and play a vital role in the sculpting of land. This program shows landscapes formed by rivers, the various types of rivers, the basic parts of a river, and how characteristics of rivers — their slope, channel, and discharge — erode and build the surrounding terrain. Aspects of flooding are also discussed.
#20 Running Water II: Landform Evolution -- Running Water II: Landform Evolution recognizes
the roles human activity can play in intensifying or reducing flood danger, and describes the
process by which streams and valleys are shaped and landscapes formed.
The Colorado River is a powerful geologic
agent — powerful enough to have carved the
#21 Groundwater -- Groundwater explains how groundwater is distributed and measures its
importance to human life.
Approximately three-quarters of Earth’s surface is covered by water. But most fresh water comes from underground. Topics of this program include aquifers, rock porosity and permeability, artesian wells, the water table, cave formation, sinkholes, and how groundwater may become contaminated.
#22 Wind, Dust and Deserts -- Wind, Dust and Deserts covers the formation and location of
deserts and their logic features.
Land in arid climates is shaped in particular ways. This program shows how deserts are defined by infrequent precipitation and how desertification relates to proximity to the equator, proximity to mountains, and ultimately plate tectonics. Images of landscapes illustrate how wind creates features such as dunes, playas, blow-outs, and even oases.

of waves in affecting coastal landforms.
This program shows the dynamic interaction of two geologic agents: rocky landmasses and the energy of the ocean. Aspects of waves — their types, parts, movement, and impact on the shore — are illustrated. The program also covers shoreline characteristics, currents, sea barriers, tides, and how the greenhouse effect could impact sea level and coastal lands.
#25 Living With Earth, Part I -- Living With Earth, Part I expresses human responses to the
destructive forces of natural phenomena, such as earthquakes and landslides.
#26 Living With Earth, Part II -- Living With Earth, Part II explores the impact of human activity
on Earth and discusses ways in which people can shape their actions to benefit Earth.
Since the nineteenth century, humans have turned to the Earth for energy sources to fuel their industry. This program discusses where oil comes from, how it is extracted, and how it is converted into energy. The effects of oil drilling and the burning of fossil fuels are also addressed, and the potential of alternative energy sources is considered.
Oceanography Video Series
From the detailed observations of Lt. Pelham aboard HMS Challanger to the mapping of the oceans by satellites and autonomous undersea vehicles, the study of the ocean is as dynamic and challenging as the sea itself. Now you can introduce students to the fascinating field of oceanography with The Endless Voyage.
The Endless Voyage, successor to the Emmy Award-winning video series, Oceanus, focuses on the marine environment as a unique and important part of life on earth. The 26 half-hour series stands alone but can be combined with the leading textbooks in the field. Supplementary material includes a student study guide and faculty guide as well as customized online material.
