Old Faithful...


Old Faithful is a cone geyser located in Yellowstone National Park in Wyoming, United States. It was named in 1870 during the Washburn-Langford-Doane Expedition and was the first geyser in the park to receive a name.
Old Faithful can vary in height from 100-180 feet with an average near 130-140 feet.
More than 1,000,000 eruptions have been recorded. Harry Woodward first described a mathematical relationship between the duration and intervals of the eruptions in 1938.Old Faithful is not the tallest or largest geyser in the park; those titles belong to the less predictable Steamboat Geyser.The reliability of Old Faithful can be attributed to the fact that it is not connected to any other thermal features of the Upper Geyser Basin.
The average height of an eruption is 145 feet (44 m).
Intervals between eruptions can range from 35 to 120 minutes, averaging 66.5 minutes in 1939, slowly increasing to an average of 90 minutes apart today, which may be the result of earthquakes affecting subterranean water levels.
1⁄2 to 5 minutes.
Between 1983 and 1994, four probes containing temperature and pressure measurement devices and video equipment were lowered into Old Faithful. The probes were lowered as deep as 72 feet (22 m). Temperature measurements of the water at this depth was 244 °F (118 °C), the same as was measured in 1942. The video probes were lowered to a maximum depth of 42 feet (13 m) to observe the conduit formation and the processes that took place in the conduit.

Snowflake Formation...

Image
A snowflake begins to form when an extremely cold water droplet freezes onto a pollen or dust particle in the sky.  This creates an ice crystal. As the ice crystal falls to the ground, water vapor freezes onto the primary crystal, building new crystals – the six arms of the snowflake. The ice crystals that make up snowflakes are symmetrical (or patterned) because they reflect the internal order of the crystal’s water molecules as they arrange themselves in predetermined spaces (known as “crystallization”) to form a six-sided snowflake.  Ultimately, it is the temperature at which a crystal forms — and to a lesser extent the humidity of the air — that determines the basic shape of the ice crystal.  Thus, we see long needle-like crystals at 23 degrees F and very flat plate-like crystals at 5 degrees F.   The intricate shape of a single arm of the snowflake is determined by the atmospheric conditions experienced by entire ice crystal as it falls.  A crystal might begin to

TAJ MAHAL -Among Seven Wonders Of The World!

Image
The Taj Mahal is an ivory-white marble mausoleum on the south bank of the Yamuna river in the Indian city of Agra. It was commissioned in 1632 by the Mughal emperor, Shah Jahan, to house the tomb of his favourite wife, Mumtaz Mahal. It is listed as one of the New Seven Wonders of the World.   The tomb is the centre piece of a 17-hectare (42-acre) complex, which includes a  mosque  and a guest house, and is set in formal gardens bounded on three sides by a  crenellated  wall. Construction of the mausoleum was essentially completed in 1643 but work continued on other phases of the project for another 10 years. The Taj Mahal complex is believed to have been completed in its entirety in 1653 at a cost estimated at the time to be around 32 million  rupees , which in 2015 would be approximately 52.8 billion rupees ( U.S. $ 827 million). The construction project employed some 20,000 artisans under the guidance of a board of architects led by the court architect to the emperor,  Usta
