bullet

This 3-unit "College Transfer" Lecture course
 
bullet

examines the materials and physical features of the earth's surface, their evolution over time through the dynamic interactions of processes driven by earth's internal energy system and those at the solar-terrestrial interface, and the related issues like earth hazards, environment and resources; and

bullet

satisfies the general education requirement in physical sciences for the baccalaureate degree programs in North American universities and colleges.

 

bullet

After successfully completing this course, therefore, the student should be able to
 
bullet

describe the forces that shape our natural environment, even in situations where the underlying  processes are too sluggish and too large-scaled to be amenable to direct physical experimentation and testing;

bullet

analyze the 'how' and 'why' of the distribution of earth resources that enable us to intelligently search for coal and iron deposits without which industrial age would not have been possible, oil and natural gas without which the modern technological society is hard to imagine, the water and soil resources without which the food needs of our ever growing population would be impossible to sustain, even sand and gravel for construction;

bullet

explain how the fatalities from such geological hazards as earthquakes, volcanoes, floods, coastal erosion, collapsing ground surfaces, landslides, and the like, can indeed be minimized and thus develop the ability to evaluate different fatality mitigation programs in terms of the validity of their underlying scientific assumptions; and

bullet

establish the geological connections that bridge meteorology, ecology, biology, physics, chemistry, economics and ethics to form the basis for our efforts to prevent environmental degradation.

 

bullet

The course should therefore sharpen your skills of critical reasoning and articulation.

http://www.pbs.org/als/earth_revealed/erigdescrip.htm#descriptions

This 26-part 13-hour videotape series presents a comprehensive study of the Earth's physical processes and properties, with emphasis on understanding the scientific theories behind the geological principles. These principles are vividly documented with the assistance of on-location footage at major geological sites around the world. Presented are both the dramatic forcesvolcanic activity and earthquakesas well as the more subtle and ever-present elements of the geological process. Earth Revealed: Introductory Geology also illuminates the often unrealized link between human activity and geological change.

bullet

MODULE I: Introduction

bullet

Video Episode 101: Down to 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.

bullet

Video Episode 102: The Restless Planet

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 Newton. Unique characteristics of Earth are also discussed.

bullet

MODULE II: Plate Tectonics: The Unifying Model

bullet

Video Episode 103: Earth's Interior

Oil wells do more than just produce oil they serve as windows to Earths interior. This program introduces the topic of geophysics, exploring methods of studying what lies beneath Earths surface. Geophysicists use seismic wave studies, variations in temperature, magnetic fields, gravity, and computer simulations to create models of deep structures.

bullet

Video Episode 104: The Sea Floor  

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.

bullet

Video Episode 105: The Birth of a 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.

bullet

Video Episode 106: Plate Dynamics

This program examines the movement and interaction of tectonic plates, which account for a vast array of geologic formations and phenomena from Californias San Andreas Fault to the Rift Valley of eastern Africa. The program covers convergent boundaries, subduction, hotspots, and the debate over what drives plate motion.

bullet

Video Episode 107: Mountain Building

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.

bullet

Video Episode 108: Earth's Structures

A visit to the Grand Canyon lays the foundation for this exploration of rock layers and deformation. The program covers sedimentation, major structures, the methods used to examine them, and how petroleum may be trapped inside them. It also looks at tectonic force and the different types of stress involved in the formation of geologic structures.

bullet

Video Episode 109: Earthquakes

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.

bullet

MODULE III: Geologic Time and Life

bullet

Video Episode 110: Geologic Time

To illustrate the immensity of geologic time, the entire span of Earths existence is compressed down to a year. The timeline of major geologic events is superimposed onto the year for a condensed view of Earths 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.

bullet

Video Episode 111: Evolution Through Time

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.

bullet

MODULE IV: The Rock Cycle

bullet

Video Episode 112: Minerals: The Materials of Earth

Minerals have been indispensable to human civilization. This program looks at the variety of minerals, their atomic and crystalline structures, and their physical properties such as hardness and luster. Petrologists methods of sectioning rocks are shown, and gems, precious metals, ore excavation, and the value of silicates are discussed.

bullet

Video Episode 113: Volcanism

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 Mount St. Helens serves as one example.

bullet

Video Episode 114: Intrusive Igneous Rocks

Most magma does not extrude onto Earths 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.

bullet

Video Episode 115: Weathering and Soils

The Cleopatras Needle obelisk in New York Citys 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.

bullet

Video Episode 116: 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 rocks 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.

bullet

Video Episode 117: Sedimentary Rocks: The Key to Past Environments

This program returns to the Grand Canyon: its exposed layers of sedimentary rock allow scientists to peer into the geologic past. The movement of sediment and its deposition are covered, and the processes of lithification, compaction, and cementation that produce sedimentary rocks are explained. Organic components of rock are also discussed.

bullet

Video Episode 118: Metamorphic Rocks

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.

bullet

MODULE V: Carving the Landscape

bullet

Video Episode 119: Running Water I: Rivers, Erosion and Deposition

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.

bullet

Video Episode 120: Running Water II: Landform Evolution

The Colorado River is a powerful geologic agent powerful enough to have carved the Grand Canyon. This program focuses on how such carving takes place over time, looking at erosion and deposition processes as they relate to river characteristics and type of rock. The evolution of rivers is covered, along with efforts to prevent harmful consequences to humans.

bullet

Video Episode 121:Groundwater

Approximately three-quarters of Earths 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.

bullet

Video Episode 122:Wind, Dust and Deserts

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.

bullet

Video Episode 123: Glaciers

Many of the worlds most beautiful landscapes were made by glaciers. This program shows how, explaining glacial formation, structure, movement, and methods of gouging and accumulating earth. The program provides images of glaciers and glacial landforms such as moraines, and discusses how study of glaciers may help us understand ice ages and the greenhouse effect.

bullet

Video Episode 124: Waves, Beaches and Coasts

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.

bullet

MODULE VI: Living With Earth

bullet

Video Episode 125:  Living With Earth, Part I

Scenes of San Francisco before the Loma Prieta earthquake introduce this program addressing how humans are learning to cope with earthquakes. Various groups and agencies are studying the San Andreas Fault and the damage caused along its path to better understand how earthquakes ravage the land. Methods of studying earthquakes are reviewed.

bullet

Video Episode 126: Living With Earth, Part II

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.
