Our planet is enveloped by air-its atmosphere. As this informative program explains, the atmosphere has several layers, each having its own properties. The weight of air pressing on the Earth is called atmospheric pressure, and it varies according to the weather. The atmosphere, with energy from the sun, drives the world's "weather machine." In addition, the angle of the sun's rays determines the climate in various regions. But the overproduction of greenhouse gases seems to be making the Earth's overall climate warmer.

This program introduces coastal climates in general and the Mediterranean climate in particular. It stresses that uneven heating of land and ocean accounts for the winds and humidity typical of both climates. The program explores the unique ecosystem of coastal climates. And it highlights the rich civilization that has developed along the shores of the Mediterranean, based on traditional industries such as olive growing and sheep herding and newer ones such as tourism.

Desert regions have hot, dry climates, with rain sometimes coming only once every few years. How can animals and peole adapt to this harsh environment? As this program explains, animals of the desert are mostly nocturnal, while people wear light, flowing clothes. Subtropical climates can also be dry and hot, such as in the thorny Australian bush country. Here too, adaptations are necessary for survival. The program shows the life of Australian Aborigines, who ages ago learned to live in the bush.

The tropics are the region of rainforests and savannahs. As this program shows, tropical rainforests are very warm and humid throughout the year, conditions supporting many species of plants and small animals. In a savannah, there is also little variation of seasons. But the dryness of the environment means fewer trees and more grass, so savannahs are home to herds of large animals. The search for food and water in a savannah requires cleverness and good legs, so both humans and animals here are migratory.

The weather changes every day. Climates also change, but slowly-over centuries or even millennia. The Earth has known cycles in which ice ages alternate with perods of warmth. As this informative program explains, these cycles have been natural phenomena. But humans may be responsible for the current bout of global warming. Industrialization, urban sprawl, and overpopulation may all be contributing to the problem.

This program shows the adaptations that people, plants, and animals have made to survive in the harsh climates of mountains and steppes. In high mountainous regions, there is snow cover for many months of the year, but some plants and animals have adapted to this frigid environment. And in the far north, deep within the Asian continent, the steppe of Mongolia is a barren land with no trees and only few shrubs. Nonetheless, a robust nomadic people live here with their horses.

Oceans act as temperature regulators, bringing mild weather to coastal areas. As this program explains, agriculture flourishes when plants are protected from constant wind, so coastal farmers often put up hedgerows. The oceans are the realm of islands, which have their own special climate, called insular. The moderate temperatures and moisture-laden winds of island environments are optimal conditions for living things, so islands have been widely colonized by plants, animals, and humans.

This program explores the Earth's polar and subpolar regions and describes the people, plants, and animals that live there. Computer animations show how the angle of the Earth's axis produces the Land of the Midnight Sun and how the planet's magnetic field causes the aurora borealis, or northern lights. The narrator explains that the inhabitants of polar and subpolar regions are highly dependent on their natural environments: In the subpolar tundra and taiga, the Saami people (Laplanders) depend on reindeer herds, while in the Arctic, the Inuit hunt seals.

With the aid of computer animations, this program explains how cumulonimbus clouds develop into thunderstorms and how cyclones or hurricanes form over tropical oceans. The program explains that tornadoes occur over landmasses-especially in the United States-and cover a much smaller area than cyclones or hurricanes do. Within that small area, however, tornadoes can be incredibly violent. The program closes with a sequence explaining how houses are constructed to withstand tropical cyclones.

Live-action film footage, maps, and computer animations introduce the climate of temperate regions in Europe, comparing them the continental regions of both Europe and North America. Students learn that temperate climates, produced by proximity to the ocean, are characterized by moist air and relatively little variation in temperature from summer to winter. The moderate climate of temperate regions makes the areas ideal for agriculture, wildlife, and the growth of cities. In contrast, continental regions are far colder in winter and are afflicted by many severe storms in the summer. Nevertheless, people and wildlife also thrive in continental climates.

Humidity has helped life develop on Earth. The "water cycle," the process of evaporation, condensation, and precipitation, leads to the formation of clouds and water falling as rain, snow, fog, mist, drizzle and other solid or liquid types. Each cloud belongs to a specific category, but they are all formed in a similar way: rising water vapor condensing at high altitudes drops back to Earth, and the cycle starts again.

Experiencing powerful weather and understanding the water cycle's part in it go hand in hand in this production. The instability caused by the cycle results in warm and cold air masses battling against each other along boundaries or fronts. These fronts move around the globe, and are exacerbated by the jet streams of wind currents high above. The interaction of these forces is shown to be particularly strong in the mid-latitudes, producing floods of various kinds. Live-action footage shows flooding and storms around the world, adding powerful imagery to the graphic demonstrations.

Find out why the solid-seeming Earth is actually a changing body, constantly destroying and rebuilding itself. Plate tectonics motion is clearly demonstrated as the source of this dynamism through exciting live-action and computer graphic images. We learn how seismology helps reveal the earth's structure, how the plates' collisions create earthquakes, and how the Richter scale works. Other earthquake-related terms such as amplitude, magnitude, aftershocks, subduction, and epicenter are demonstrated in clear detail, showing why plate tectonic theory is the foundation of modern geology.

Understand that the causes of severe weather are the basic causes of all weather patterns. The Sun's energy, in concert with the Earth's rotation, is demonstrated graphically as the source of circular wind motion. When this motion combines with the water cycle, differential air pressure and temperatures result, and soon cyclonic air movements increase in volume and power. One of the most extreme of these movements occurs over water, and at a certain intensity, spawns hurricanes or cyclones.

Grasping the size of our galaxy requires a comprehension of the concept of light years, which this program lays out in clear detail. Through comparison with earthly time frames, we grasp the fact that the light from distant stars is actually elapsed cosmic time. The formation and destruction of stars, the phenomenon of pulsars, and the existence of black holes give us a stunning overview of our galactic neighborhood and its components. And, we learn that galaxies are composed of huge gas and dust clouds, called nebulae, which condense under gravitational pull into rotating billions of stars, and planets.

Join us as we explore the inner part of our solar system, starting with the Sun and its structure. We also see how gravity and momentum keep the planets orbiting around the Sun elliptically, as first revealed by Kepler. Then we fly over and experience the contours of Mercury, Venus and Mars. Finally, we learn how Planet Earth's uniquely balanced attributes (favorable position from the Sun, rotation for suitable climate, supporting atmosphere, flowing water, a moon that creates cleansing tides, perfect size for optimum gravity, protective magnetic field) make it the only planet both beautiful and capable of supporting life.Join us as we explore the inner part of our solar system, starting with the Sun and its structure.

Why is the southern Middle West part of the United States particularly prone to violent storms called tornadoes? In spring, the collisions of still frigid winds from Canada with the warm upwelling breezes from the Gulf of Mexico create thunderstorms. If these collisions accelerate, "super cells" of even faster rotations occur, creating more upwelling and circulating, with hail, and then funnels of wind, culminating in a chain reaction. This process is clearly demonstrated by descriptions underpinned with computer graphic images and live-action footage blasting before our eyes.

Find out why volcanoes tend to be linked in a linear chain around the Pacific Ocean, called the "ring of fire." Expanding upon the theory of plate tectonics, this program uses live-action and computer graphic images to show how plates constantly collide or pull apart, creating molten rock beneath the surface that wells up from time to time, forming volcanoes. The types of volcanoes are defined and described, and the buildup and explosion of Mt. St. Helens' volcano dramatically reveals the process in action. Volcanic activity from other parts of the globe is also shown.

Grasp the significance of the water of life as never before. Without this resource of a flowing changeable bond of two atoms, life as we know it would not exist. Water's properties of solvency, surface tension, and capillary action are shown to be essential for transporting nutrients so that living things can use them. Water's peculiar three states of matter make possible the hydrologic cycle, without which the purification and recycling of the fixed amount of water on Earth would not occur. So, this program strikingly demonstrates the synergy between the processes of earth and life sciences.
