Iguaçu Falls

Iguaçu Falls (Iguassu) is the most powerful waterfall on earth, although not the largest or highest. Nothing else has so manyseparate cascades. There are approximately 275th Between cascades there are many rocky islands.


Ocean-like, wide at 4 km of water falling from the Iguaçu semicircular edge of the plateau of Parana 72 m down. Water flows intoa narrow gorge, called La Garganta del Diablo (Devil's Throat), and later split into numerous cascades.


Fully rainy season, from November to March to Devil's Gorge is poured in one second approximately 13.6 million gallons of water.is the amount sufficient to fill six Olympic swimming pools. The deafening roar of the waterfall can be heard at a distance of 24 km.

Cathedral in Brasilia

In 1956 the city began construction of Brasilia, where the urban and architectural plan developed by two Brazilian architects LucioCosta and Oscar Niemeyer. The first of them was responsible for the spatial plan, while the second was to design public buildings, including the building of the cathedral.


On 12 September 1958 he was a cornerstone for the construction of the cathedral. Two years later, construction was completed, and 31 May 1970 the church was dedicated.


Construction of the cathedral consists of 16 concrete columns that are arranged in a circle with a diameter of 70 meters. The columns in the shape of a parabola and a weight of 90 tons symbolize the hands facing upward toward the sky. Between the columns were fitted with stained glass fibers. They have the shape of a triangle with base 10 m and a height of 30 m. stained in blue, white and brown were painted in 1990 by Marianne Peretti.


Before entering the cathedral, there are four bronze sculptures with a height of 3 m, which represent the Evangelists. They weremade ​​by the sculptor Dante Croce in 1968.


Inside the cathedral there are three statues of angels, which were suspended on steel ropes. They were made ​​in 1970 by AlfredoCeschiatti Croce and Dante. The smallest angel is 2.22 m tall and weighs 100 kg, the average is 3.40 m tall and weighs 200 kg,while the largest is 4.25 m tall and weighs 300 pounds.

Mayon

Without a doubt the most beautiful volcano in the world. The perfect cone rising above the coastal plain. Nay, even from spacelooks like an almost perfect circle. And that one of the most active, almost always with its top rises to smoke.


Mayon is not high, only 2463 meters above sea level. But his relative height is 2447 m above ground level. Volcano is doing soreally big impression. It lies on the coastal plain fact, near the sinuses Lagonoy and Albay, but also not far from the Sibuyan Sea.Because at this point in Luzon pulls out a narrow and long Bicol peninsula. Mayon is in the southern tip of Luzon, the northern end of 200-thousand city of Legaspi, Albay province's capital. Not far is the San Bernardino Strait, which separates the island ofLuzon from Samar.


Mayon, that little showy, it is still very active. Over the last 400 years recorded 49 explosions. At fifty it looked in December 2009.At that time, authorities evacuated more than 50 thousand. inhabitants within a radius of 8 kilometers from the volcano. Farmershad to take up to three times the strength, because in spite of the danger they returned to their homes, where they remained after all the inventory. At a safe distance from the volcano greedily gather thrill tourists. A Mayon rarely fails in this situation ...


Mayon is a stratovolcano. Alternately throws magma and pyroclastic material (heated to temperatures up to over a thousanddegrees of dust, gases and volcanic bombs of various sizes) and is shaped more or less similar to the cone. Mayon has allstratovolcanos most regular shape. Slope, depending on the height varies from 35 to 40 degrees. Lines do not interfere with anyso-called side. Parasitic cones or other inequalities. Why, despite frequent outbreaks still maintains impeccable appearance?Because what the explosion will throw in the air, falls and rebuilding strained eruption cone. The current creates a lava andpyroclastic materials from 2006. Then broke out last time.


And where such activity? Well, the fact that it is part of the surrounding Pacific Ring of Fire, stretching from New Zealand forTonga, Melanesia, the Philippines, Japan, the Kurile, Aleutian, after trailing by two American Cordillera. In this region there is 81 percent of earthquakes and there smokes and spits fire 90 percent of active volcanoes. It is on this site connect to many of the lithosphere plates. It's basically still clash. Pushing at each other, move away, etc., and any movement causes reactions in the form of earthquakes and volcanic eruptions.


Mayon eruption was the most tragic February 1, 1814 year. Initially it seemed that the eruption will be a weak, much smaller than the previous one from 1766, so residents ignored the eruption. But when they saw the gray clouds rushing down pyroclastic runoff, it was too late. 2.2 thousand were killed. people. Cagsawa town disappeared under a layer of ashes. Only the church bell towerjutting above the new level ground. The layer of ashes was 9 meters. During the outbreak of the 23-30 June 1897 year at the15-meter-thick layer of stones and ashes disappeared Bacacay town. San Roque, Misericordia and Santo Niño burned. Killed more than 400 people.


As the Philippines is a densely populated even minimal losses. During the tambora explosion in 1815 killed 117 thousand.people. The eruption of Krakatoa in 1883 consumed 36 thousand. people and the Colombian Nevado de Ruiz in 1995 - 23thousand. people. Why? We do not know. Often lower volcanoes that mention only Vesuvius, lakes, or even lying in the middle ofMount Pinatubo Luzon, exploded much stronger. Pinatubo in 1991 had lost one-tenth of his height (he was 1745, and now has a1486 meters high). Volcanology is still young and aspiring science, and that everything has a beginning in the liquid magma within the Earth, it must be based on unreliable models.

In recent years, thanks to advances in science, volcanologists can warn in time before the eruption. When seismographs recordlow-frequency earthquakes, shock, followed every minute, and even more frequently (about two thousand a day), and land on the ground level is raised (even a few millimeters), a sign that deep inside the cone builds up more and more magma, which may at any time of the hellish roar skyrocket.


In 1984, evacuated more than 73 thousand people and no one was killed. But in 1993, some ignored the warning. I killed 77farmers in their fields and farms. Also, the last eruption, in 2006, fortunately without casualties was held.


But volcanoes are unpredictable. Sometimes everything seems to indicate that the eruption about to happen, but everythingspreads the bones. In 2006, Mayon scare in June, and broke out in August. Similarly, in 2009. Symptoms of impending outbreakreported since June, 11 November eruption occurred, but small. And there was peace, until mid-December, when he woke upagain Mayon. December 14 began evacuating tens of thousands of people. 16 December the volcano ejected plume of smokeand dust, and then began to belch lava. And so, until December 20.


Locals are proud of their volcano. Once it looks really nice, two, that they earn on it. Due to the high activity come here not onlyscientists, but also many tourists.


Mayon was prepared by the Philippines as their candidate for the title of the Seven Wonders of Nature, but had to give way to the underground river of Puerto Princesa.

Googleplex

Googleplex is the headquarters of Google in Mountain View, California. Located in Silicon Valley, which is considered to be the center of American industry, new technologies, directly adjacent to the headquarters of companies such as Alza, the Mozilla Foundation and Microsoft.


Work on the complex was launched in 1994, and completed it in 1997. Worked on the project Silion Graphics Inc. company. (SGI)architecture firms in San Francisco and the city of Mountain View.


The project aimed to develop a complex of buildings designated for corporate headquarters, which harmonized with public parks.Built for this purpose underground parking for over 2,000 vehicles, thus enabling the creation of open space.


The complex consists of four major and several smaller buildings with a total area of ​​47,000 square meters. They were originallybuilt for Silicon Graphics Inc.. However, in 2003 Google began to rent space in it, and three years later purchased the entirecorporation for $ 319 million.


Google tries to ensure maximum comfort and convenience, which is why the interior of the building are the giant rubber ball, in the lobby is a piano, and on the wall displays the current Google search queries. The complex has a gym, free laundry, 2 smallswimming pools, beach volleyball and eleven cafes with different menus. Google also has a replica of SpaceShipOne, the firstprivate manned spaceship and the skeleton of a dinosaur.


About 30 percent of the demand for electricity Googleplexu covered with solar panels, which are capable of generating 1.6megawatts of electricity. Their installation began in late 2006. One third of the panels are mounted on poles in the form of solartrees, and the other was placed on the roofs.

Old Faithful Geyser

Yellowstone is the first national park in the world (established in 1872), and also the largest U.S. national park. The overwhelmingpart of it lies on the territory of the state of Wyoming. It is a volcanic plateau in the Rocky Mountains, full of mountains, lakes and forests. Other attractions of this area are the cliffs made ​​of black obsidian and thousands of geysers and hot springs.


The term comes from the Icelandic geyser geysa words that mean burst or gush. Deep below the earth surface structure are very hot rocks. They heat the filling hole or channel water to the boil, then boiling water and steam will be thrown to a considerableheight.


After emptying the geyser channel gradually fills with water again in August and the process repeated. Old Faithful geyser is activecontinuously for at least 200 years. Every hour 45 thousand. liters of boiling water is thrown away for 5 minutes at the height of 30-45 meters.

The king of kings

Near the town of Monroe's largest statue of Christ in the United States. He has been sculpted from the chest and shoulders andhis head tilted toward the sky.


The sculpture, erected in September 2004, has almost 19 meters high and weighs over 7 tons. It was designed by Brad Corieland sculpted James Lynch.


The statue is made of wood and Styrofoam, which were mounted on a steel structure. The whole is covered with fiberglass andresin.

Stonehenge

Stonehenge is in the English county of Wiltshire, about 8 miles (13 km) north of Salisbury. It is composed of earthworks surrounding a circular setting of large standing stones and is one of the most famous prehistoric sites in the world. Archaeologists think that the standing stones were erected around 3200 BC and the surrounding circular earth bank and ditch, which constitute the earliest phase of the monument, have been dated to about 3100 BC.

Golden Gate Bridge

The bridge connects the two peninsulas on the two banks of the San Francisco Bay. It was built by Joseph  Strauss Baermanna. It has a length of 2800 meters and the distance between the pylons is 1280 meters. Pylon  height is 227 meters, and can flow under the bridge even ocean-going vessels, since bridge is located at an  altitude of 66-72 meters above the water surface.

The construction of the bridge began in 1933 and lasted until 1937. Work on design was extremely dangerous.  Strong currents, fog or storms hampered the work of the workers effectively. Particularly dangerous was the  stage of the hanging ropes, each of which was 91 cm in diameter and consisted of 27,000 steel wires.

Golden Gate Bridge and quickly began earning to 1971 turned to construction costs, which totaled $ 75 million.  In the first year he traveled more than 4 million vehicles. Currently, the bridge each day passes 120,000 cars.

In the seventy years of existence, the Golden Gate Bridge has survived many earthquakes, hurricanes, and the  passage of time. In 1989, he survived one of the worst earthquakes of a magnitude 7.1 on the Richter scale.

Bridge, except that communication is an excellent route, also attracts tourists and, unfortunately, suicide.  Since the inception of a bridge over a thousand people took their own lives by jumping the barriers.

Brooklyn Bridge

Brooklyn Bridge is one of the oldest suspension bridges in the world and ranked among the completion of the  largest steel suspension bridges. The construction is located on the East River and connects New York districts  Brooklyn and Manhattan.

Brooklyn Bridge construction started in 1869, and May 24, 1883, there was his opening. The structure is made  ​​of steel, stone and granite, and cost about 15.1 million dollars. A bridge designed and built an American  Architects: John Augustus Roebling and his son Washington Augustus Roebling.

Length of the Brooklyn Bridge is 1,834 meters. The main span is above the water is 486 meters and it spans two  pylons with a height of 84 meters. Side spans, which connect the pylons of the banks have 284.5 feet long. The  bridge is located 41 meters above the water, it is about 26 meters wide, and its total weight is 14 680 tonnes.

Most support the nearly 1,100-meter four cables that are 40 centimeters in diameter and consist of a bundle of  19 cables, each containing 278 wires. Depth of foundations under water on the side of Brooklyn is 13.5 meters,  while the side Manhattan'u - 24 meters.

At the beginning of the bridge served only horse and tram traffic, now has six lanes for cars and sidewalks for  pedestrians and cyclists.

Andros Blue Holes

Andros is the largest island of the Bahamas. At its eastern coast is a belt of deep water, called the tongue of the Ocean. Along this stretch belt shoals and coral reefs, and with them spread out the dark depths. These are the inputs to some of the most amazing underwater caves and corridors in the world.


Flowing water quite easily washes away the limestone rock, carving caves and tunnels. Layers of limestone on the islands of The Bahamas is known the world thickest layers of this mineral. They form under the water layer with a thickness of 8 km. On the coral reefs are formed and while the limestone sinks (on average 1 cm per 100 years), weight increased very coral. It is known thatsome of them are located at a depth of more than 3050 m, and their length exceeds 2300 m.

Residents Bahamas blue hole called churning, or blowing holes, due to the rapid movements of water that flows out of the cavesor affect them. When the flow increases, the holes leading to the formation of dangerous caves, strong eddies. When the watersubsides, the dome umbrella holes spit out water. Exploring caves can be very dangerous. The water flow is so strong that divers can reach them only lasting 20 minutes during a quiet period called the dead waters. Several people have drowned here, whenthey ended up oxygen.
