--------- 비디오 차례 ---------
1. Down to Earth - 금성, 화성 지구의 차이, 지구의 자연 자원, 지구의 전반적 소개
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.
2. The Restless Planet 천문학적 지구의 역사 - 코페르니쿠스, 갈릴레오, 케플러, 뉴턴
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.
3. Earth's Interior - 지구의 내부 구조 - 원유의 매장, 지진파 연구, 지구 자기장, 중력
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 - 해양- 해양저, 해양내 화산활동, 해저산맥, 해령, 심해의 생물들
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 - 판 구조론의 탄생과 그 발전, 알프레드 베게너, 해양확장설, 대륙이동설, 고지자기, 팡게아
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 - 계속해서 움직이며 변하는 지구의 판- 산안드레아스 단층과 동아프리카의 열곡대, 침강대
This program examines the movement and interaction of tectonic plates, which account for a vast array of geologic formations and phenomena — from California’s 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.
7. Mountain Building - 산맥의 형성, 조산운동, 산맥형성시의 형성되는 암석의 종류들...
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 - 지층의 배열과 구조, 그랜드캐년의 지층구조와 변성, 퇴적, 퇴적된 지층내 원유의 매장
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.
9. Earthquakes - 지진과 지진이 발생하는 단층, 지진파, 진원지와 진앙, 지진그래프의 설명
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 지질시대와 지구의 진화, 화석과 방사선 탄소를 이용한 연대측정
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 시간에 따른 진화, 화석에 나타난 진화의 과정
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 - 지구내의 광물 자원 : 다양한 광물과 결정구조, 굳기와 조흔색
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.
13. Volcanism - 화산, 화산 분출, 분화구 , 용암, 마그마, 화산암,
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.
14. Intrusive Igneous Rocks - 관입 화강암, 마그마의 관입, 화강암, 석영의 구조
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 - 풍화와 토양, 날씨, 기후, 기계-화학적 풍화작용, 온도, 토양의 침식, 환경의 영향
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 산사태, 지층의 변형
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 퇴적암- 과거의 환경을 알려주는 단서, 그랜드캐년의 퇴적
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.
18. Metamorphic Rocks - 변성암, 암석의 재결정 작용, 변성암의 생성, 변성암과 판구조의 관계
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 - 강의 침식과 퇴적, 다양한 강의 종류, 강의 성질
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: Landscape Evolution - 강이 만드는 지형 구조와 모양
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.
21. Groundwater - 육지의 물
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 - 바람과 모래먼지, 사막
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.
23. Glaciers - 빙하 , 빙하의 구조, 빙하의 형성과 그 종류
Many of the world’s 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.
24. Waves, Beaches and Coasts - 파도와 해변, 해안선
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 - 살아있는 지구 1 : 산안드레아스 단층과 지진의 연구방법
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.
26. Living With Earth, Part II - 살아있는 지구 2 - 원유의 매장, 화석연료
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.
