According to Scientists from European Space Agency (ESA) from the Swarm Data, "T he magnetic field around the earth has lost almost 10% of its strength over the last two century". The Swarm satellites is able to identify and measure the the various magnetic signals that combine to make up the Earth's magnetic field. A  rapid shrink has been observed in the South Atlantic. A large and rapid shrink has been observed in this  between Africa and South America  over the past 50 years just as the area itself has grown and moved westward. The weakening of the magnetic field is also causing technical difficulties for the satellites and spacecrafts orbiting the planet. Researcher said that "T here is a chance that the time for Earth's pole reversal is coming near"....

Gold is metallic, with a yellow colour when in a mass, but when finely divided it may be black, ruby, or purple. It is the most malleable and ductile metal; 1 ounce (28 g) of gold can be beaten out to 300 square feet. It is a soft metal and is usually alloyed to give it more strength. It is a good conductor of heat and electricity, and is unaffected by air and most reagents. Gold is usually alloyed in jewellery to give it more strength, and the term carat describes the amount of gold present (24 carats is pure gold). It is estimated that all the gold in the world, so far refined, could be placed in a single cube 60 ft. on a side. The most common gold compounds are auric chloride (AuCl 3 ) and chlorauric acid (HAuCl4 ). A mixture of one part nitric acid with three of hydrochloric acid is called aqua regia (because it dissolved gold, the King of Metals). It is unaffected by air and most reagents. Applications Gold is used as buillon and in jewellery, glass and electronics. Jewellery cons...
