Mystery about "Radioactivity and the earth"

Most of the energy responsible for the geographical history of earth can be traced to the decay of the uranium,thorium and potassium isotope it contain. The earth is believed to have came into being perhaps 4.5 billion years ago as a cold aggregate of the smaller bodies that consisted largely of metallic iron and silicate material that had been circling the sun.

Heat of the radioactive origin accumulated in the interior of the infant earth and the time lead to partial melting.The influence of gravity then caused the iron to migrate inward to form the molten core of today's planet;the geomagnetic field comes from electric currents in the core.

The lighter silicates rose to form the rocky mantle around the core that makes up about 80 percent of the earth's volume.

Most of the earth radioactivity is now concentrated in upper mantle and the crust, where heat it produces escapes and cannot collect to remelt the earth.The steady stream of heat is more than enough to power the motion of the giant plates into which the earth's surface is divided and mountain building, earthquakes,and volcanoes associated with these motions.

Why do the Indian telecom operators offer their services with 28 days validity, not 30 days?😡😡

Here telecom operator are very clever, b ecause telecom operators want to earn money of 13 months instead of 12 months. Let do the calculation and find out why telecom operators are offering 28 days validity. Each month they get 2 days more, therefore in a year they get additional 24 days. There are 7 month which has 31 days so they get additional 7 days.Now in case of February ,it has only 28 days not 30. So the total number of days they get are=24+7-2=29 days. So if you recharge 12 times then more 29 days are left in a year.🤔🤔 Means for another 29 days you have to recharge from that telecom operator.😫😫 So you have to recharge 13 times in a year instead of 12 times in a year. So telecom operators provide 28 days validity only. First one telecom operator started and then another telecom operators also understood this concept and they also applied 28 days validity both in data packs and voice packs.😱😱😱

Why swiss Bank is Famous for Black Money?

Hello everyone, here we are going to talk about Swiss Bank. When a person hear the name of this bank the only thing that come to our mind is Black Money.

In bank statement the account holder name is also not disclosed to any one. Here Swi...

How Hydroelectric power produced?

Water has been used to power man-made mechanisms for hundreds of years, mostly in food production in the form of a mill wheel to grind corn. However, using the kinetic energy of water probably became a reality earlier than you thought. In 1878, inventor Lord Armstrong lit his home in Northumberland using only the power of a nearby waterfall. It’s not until the latter half of the 20th Century that we began to take advantage of the massive potential of hydroelectric power. Intriguingly, both the dirty and environmentally unfriendly coal power plants and clean, green hydro-power use almost identical technology to generate power. Central to a coal-ﬁ red plant is a turbine: coal is burned to produce heat energy, which is used to boil water into steam, which then drives a turbine. Hydroelectric power removes the coal and steam elements and instead, ﬂ owing water turns the blades of each turbine. By damming a river next to a drop in elevation and releasing a co...
