Millions of tourists visit Egypt to see the only survived of the Seven Wonders of the world. Pyramids got recognized by the World Tourist organization, a kind of Oscars for the tourism industry.
Each year millions of tourists arrive in Cairo to see the one of the Seven Wonders of the World – Great pyramid and the pyramids and Hefren Mikerin located in the plateau of Giza.
It is believed that these pyramids were built before more than 4,5 thousand years and served on the Egyptian tombs pharaohs. And until now, however, researchers disagree on their exact age and purpose. In the scientific world is constantly emerge and new hypotheses the manner in which they were built massive pyramids.
The pyramids are one of the most imposing buildings survived until today. In ancient times, are a marvel size and now wonder of their age. With its 481 feet (146.59 meters) the Great Pyramid was the tallest building in the world until the 19th century. Moreover, only one of the Seven Wonders of the world that we can still see with his eyes. Indeed, when the Great Pyramid is only 449 feet high (137 meters), because it is losing some of its peak. The initial length of the side of the pyramid was 754 feet (230.33 meters) and is now 745 feet (227 meters). Ploshttta based is 13 acres, ie 568.500 square feet (52,843 sq m). According to official estimates the Great pyramid of Giza was built of stone blocks 2.300.000 with an average weight of 2,5 pt This means that the pyramid weighs approximately 5.750.000 tons! In the construction will block more light than 2 tons, and the worst blocks weigh 70 tons. Almost the entire exterior of polished limestone is removed by the Arabs before 600g to be used in the construction of mosques and other buildings in cities. This gives a rough pyramids, tiered look. The only original entrance is on the north side and 16 meters high. Only inside the pyramid of Cheops is also burial chambers and four wells . The two shafts, starting from the burial chamber of Pharaoh were found in the 1610g, and those beginning in the chamber of the queen – in 1872.
Historians are not quite firm, but assumes that the pyramid of Cheops was completed in BC 2589g. But its construction continued 20d. Soon made excavations of settlement and cemetery of this period in the vicinity of the pyramids and inscriptions found in them, clearly show that people who built the pyramids were not slaves, but artisans and peasants. Most of the stone blocks that were needed to build the pyramids were logging directly from the plateau. This is saving the hard work of transporting the blocks from other quarries along the Nile. To build the pyramids were needed 40.000 people. We have to note that the Egyptians did not know then wheel and all work is done without any machinery.
Great pyramids of Giza are tombs of the pharaohs of the fourth dynasty Hefra (gr-Hefren), Khufu (Cheops-town) and Menkaura (gr-Mikerin). Smaller pyramids were designed for the wives of the pharaohs. These facts are confirmed by the history of Herodotus, who visited the Giza 450d in BC. and found in the burial chamber of Cheops pyramid inscriptions.
This beautiful "tree" is actually an upside down paddle worm with its tentacles flowing back down its sides. It swims with a paddling motion, hence its common name while the Latin means "cut" and "wing." Some species will release glowing sparks when disturbed. 
The golden color comes from symbiotic phytoplankton called zooxanthellae inside the single celled Acantharea. The needles are made out of celestite which many of us know as a pale blue beautiful mineral. 
These larva of the sea anemone may not look familiar right now but they turn into gorgeous 'flowers of the sea" as the link shows. In the meantime, the ocean's Santas have their own hats! 
Sea angels are sea slugs - the "wings" are modifications of their foot that they use to locomote and catch prey. Their prey are sea butterflies (another species of pteropod) and the angels have co-evolved to the point that even their metabolism is closely matched to that of their prey. 
This baby starfish, unusual with 7 arms has just detached from its larval body and is sinking to the sea floor to continue its growth - it will grow to be between 40 and 60 cm! The upper arms are pale orange to reddish orange but the lower are white. Some half bury themselves to catch urchins and bi-valves. 
This tiny jellyfish is an important predator in the plankton food chain. It has 8 long sex glands just under the roof of the umbrellas and around 80 tiny tentacles at the base.
