902_05_12519046highres A magic lantern slide circa 1900. Religious slides. The 'Statutype' series of the life and work of Christ on Earth. This is a very fine and entirely new set of Slides, photographed from an original series of models sculptured by the French artist, Mestroianni. On the screen they appear almost stereoscopic, standing out well in relief owing to the shadows being real shadows, not merely painted. They are quite unique in appearance and very attractive, being printed, by a special process of our own, in a warm brown art tone. Great transparency is obtainable with this new process (Newtona), making these Slides very suitable for oil and acetylene lanterns. Messrs. Newton & Co. hold the sole right of making Slides of these copyright subjects in all English-speaking countries.Postcards of the above pictures can be obtained from Mr Noyer, 37, Boulevard de Strasbourg, Paris.

990_05_BO6-Eth-NA-CA_14HR California: c. 1930 Most villages had one or more sweat houses where the men gathered every day for the traditional custom of sweating. The earth covered house was built close to the river so the men could plunge into the water after sweating. A fire was built in the sweat house to make it hot, and the men scraped their bodies with a split deer rib to stimulate sweating. When they could endure the heat no longer, they ran from the sweat house and plunged into the nearby river.

1016_03_51225 Magmatic (or igneous) rocks generally come from Earth?s upper mantle, where magma is partially melted. Depending on their rate of cooling, these rocks will be more or less fine- grained. Plutonic (or intrusive) rocks, which solidify slowly, are coarse-grained, while volcanic (or effusive) rocks, which solidify rapidly when they reach the surface, are fine-grained.

1016_03_58464 Even though the Moon is 378,000 km away from Earth, its gravitational force is strong enough to move the oceans. When Earth rotates so that a mass of water is facing the Moon, water rises in its direction: this bulge produces a high tide. At the same time, the Moon?s gravitational pull on water on the other side of Earth is much weaker. This water is affected by the centrifugal force created by the rotation of the Earth?Moon system and tends to bulge outward, creating another high tide. If Earth were made only of rigid materials, it would still be deformed by the action of these two forces and would be egg-shaped.
DC
1016_03_58462 It is thought that the Moon was born from a catastrophic collision between Earth and a huge asteroid. The impact propelled into space enormous quantities of matter from Earth and the destroyed object. Under Earth?s gravity, the debris began to orbit Earth and became amalgamated to form the Moon.

1016_03_58322 DDT, one of the most effective insecticides used in agriculture, passes from the soil to plants, then to herbivores, carnivores, and finally to superpredators. While biomass diminishes as we go up the food chain, the quantity of DDT is transmitted with very little loss. Its concentration therefore increases at each nutritional level, and organisms at the top of the chain (such as humans) have the highest proportion. DDT, which upsets the endocrine system and can cause cancer, is now banned in many countries.

1016_03_58226 While we see a lightning flash almost the instant it occurs, thunder reaches us after a slight delay, since sound travels more slowly than light. If we count the number of seconds in the delay and divide it by three, we can estimate our distance (in kilometers) from the site where the strike occurred.
DC
1016_03_58225 As it is transmitted to the surrounding air, the great heat (30,000°C) of a strike causes the air to expand suddenly, then contract. These two movements create a shock wave that is transformed into a sound wave, thunder.

1016_03_58221 Each wavelength has a different angle of refraction. White light from the Sun is thus dispersed by each raindrop into beams of colored light that cover the entire visible spectrum, from red to violet. We actually see only one color per raindrop, but the huge number of tiny prisms forms a range of colors in our perception: a rainbow.

1016_03_58160 Most of the tornadoes in North America occur in the central United States, in a ?tornado belt? comprising the states of Texas, Oklahoma, Kansas, and Nebraska. In this region, the combination of warm winds from the Gulf of Mexico and cold winds from Canada creates ideal conditions for the formation of mesocyclones, especially in April and May. In the southeastern part of the continent (Florida, Alabama, Louisiana, Mississippi), tornado season occurs earlier, between January and March. The western United States, protected by the Rocky Mountains, is practically tornado-free.
DC
1016_03_58144 At a very high altitude (between 6,000 m and 15,000 m), very strong winds blow from west to east around Earth. These are the jet streams, which are divided into polar systems (at about 60° latitude) and subtropical systems (above the tropics). The jet stream is shaped like a flattened tube several hundred kilometers wide.
DC
1016_03_58141 From data obtained by weather satellites, computers produce maps simulating the general circulation of winds in Earth?s atmosphere. The.arrows indicate the direction of the winds, while the color zones indicate their speed. This image shows surface winds over the Pacific Ocean.
DC
1016_03_57998 Contrary to popular belief, the cycle of the seasons?that is, the periodic change of climate over the months?is due not to Earth?s distance from the Sun, but to its inclination: our planet?s axis of rotation leans about 23.5° in relation to the ecliptic (the path of Earth?s orbit). This inclination is directly responsible for the variation in sunshine hours, and thus the succession of seasons, throughout the year.
DC
1016_03_57992 The salinity of seawater is the amount of salt dissolved.in the water. On average, seawater contains 35 g of salt per liter. The more enclosed the sea, the higher its salinity. For example, salinity is lower than average in the North Pacific Ocean (32 g/l), but higher than average in the Red Sea (40 g/l). The Dead Sea is the saltiest body of water in the world, with a salinity of 330 g/l, and the Baltic Sea is one of the least salty, with a salinity of only 8 g/l. The balance between water evaporation from the oceans and precipitation is responsible for differences in salinity. Under subtropical anticyclones such as those in the Azores, evaporation is very high, and so the seawater is saltier. On the other hand, the equatorial region is subjected to strong and frequent rainfall, which results in a lower salinity level in seawater around the equator.
DC
1016_03_57991 Water and the atmosphere are constantly exchanging energy in the form of heat. The surface temperature of.the seas and oceans thus plays a fundamental role in the regulation of atmospheric processes. Measurement of seawater temperature enables us to follow the evolution of climatic phenomena, such as El Nin?o, and ocean currents, such as the Gulf Stream, and to predict the formation of cyclones. Seawater temperature also provides information on the development of phytoplankton and shoals of fish. The distribution of surface temperatures is linked to hours of sunlight, which, in turn, depends on the latitude. The temperature of the oceans ranges from 28°C, near the equator, to ?2°C, in the high latitudes (north and south), closely following the distribution of solar radiation that reaches the surface of the water.
DC
1016_03_57959 Like cyclones, tornadoes result from the circling of ascending winds around a low- pressure zone. Tornadoes are notable for their short duration (a few minutes) and the violence of the winds they generate.

1016_03_57954 TOPEX/Poseidon, a Franco-American satellite placed in an orbit of 1,330 km altitude in 1992, measures the height of the oceans around the planet. In June 1998, the large mass of cold water that began to migrate from west to east indicated the arrival of La Nin?a.

1016_03_57946 The equatorial zone of the Pacific Ocean is normally affected by the trade winds. Pushed by these constant winds, the surface water slowly moves from South America toward Southeast Asia, creating a mass of warm water that gradually swells through thermal expansion. Evaporation of warm surface water causes clouds to form, and the trade winds push these westward. Warm, humid air rises near Asia, while masses of cool, dry air descend near the South American coast. This atmospheric circulation, called the Walker cell, affects the climate of the entire Pacific zone: while the seasonal monsoon rains pour down on Asia, an anticyclone settles in over the South American coast.

1016_03_57942 The sterilization of its soil is the result of a half century of intensive agriculture. Traditionally, the periodic monsoon rains ensured wild vegetation in the region, and this protected the land from the Sun?s heat and returned humidity to the atmosphere, thus contributing to the water cycle. In cultivated fields, on the other hand, solar rays are absorbed directly by the soil, causing it to dry out.
DC
1016_03_57923 Between 1970 and 2000, the Arctic pack ice lost more than 10% of its area, dropping from 13.5 to 12 million square kilometers. It has also become much thinner. Although the melting of ocean ice does not cause the sea level to rise, it does allow the water to absorb more solar rays, which intensifies global warming. Arctic regions should see a much greater increase in temperature than the rest of the planet.
DC
1016_03_57867 In the periglacial zones of North America and Asia (beyond the areas of permanent ice and snow), the lower layers of the ground never thaw (permafrost). Only a few patches of unfrozen land provide deep water circulation, connecting the water table to the surface. As the temperature rises in the spring, the top layer of the ground (the mollisol, or active layer) thaws. The thickness of this layer, which varies from a few centimeters to a few meters depending on the latitude and temperature, determines the type of vegetation that grows on it: tundra (moss, lichens, grass, dwarf shrubs) or taiga (conifers).
DC
1016_03_57801 A city located in a valley or basin, such as London, may be subjected to smog if its winters are humid. Clouds keep solar rays from warming the surface air, so it stays cold, humid, and polluted, which maintains and accentuates the phenomenon.
DC
1016_03_57794 There are particular areas in the world where pockets of magma from Earth?s mantle rise very slowly to the surface. These places are called ?hot spots.? As magma pierces Earth?s crust, it collects and gradually begins to form small volcanic mountains in the middle of the tectonic plate. The positions of these volcanoes show the movement of the tectonic plates, which are floating on the mantle. As the plates slide, the rising magma creates a new volcano that slowly burns out. In the ocean, hot spots can be identified by the chains of volcanic islands they usually form. The islands of the Hawaiian Archipelago in the middle of the Pacific Ocean were created in this way.

1016_03_57788 Rainwater seeps into the ground and then rises to the surface in the form of a spring flowing down hills and mountains. As it is fed by more springs and meltwater from glaciers, it becomes a mountain stream, and then a young river. It continues flowing down the mountain, following steep slopes and forming waterfalls. The river carves out deep gorges, then broadens. Fed by tributaries, it becomes a large river. As it grows wider, the river forms meanders. Often, a delta forms at its mouth, saturated with the sediments that it has transported. Finally, it flows into the ocean. Water evaporation in the oceans forms clouds. The hydrologic cycle starts over.

1016_03_53562 Gently rounded or capped by tall peaks, mountains are the planet?s most striking showpieces. They are also Earth?s highest land features. Many of these massive, often steep formations are located along the edges of continents. They may form chains, or ranges, that extend for thousands of miles (or kilometers). The principal mountain ranges include the Rocky Mountains and the Andes, which run from North America all the way down through South America,.the Atlas Mountains in Africa, the Himalayas in Asia, and.the Alps in Europe. The longest mountain range in the world is at the bottom of the ocean! It measures more than 40,000 miles (65,000 km) long and reaches several miles (or kilometers) high.
