In the very beginning of earth's history, this planet was a giant, red
hot, roiling, boiling sea of molten rock - a magma ocean. The heat had
been generated by the repeated high speed collisions of much smaller
bodies of space rocks that continually clumped together as they
collided to form this planet. As the collisions tapered off the earth
began to cool, forming a thin crust on its surface. As the cooling
continued, water vapor began to escape and condense in the earth's
early atmosphere.......Read More!
Greatest EarthQuakes!
The honor of greatest earthquake of all time goes to the 1960 Chile earthquake because scientists were able to 'catch this one on tape'. In other words, there have been a lot of really big earthquakes throughout human history (and even greater ones before we came on the scene), but this one they were able to measure, record and verify its ground motion strength. The instruments that seismologists use to measure earthquake magnitudes are designed to detect the amount of energy released by the movement of the ground during a quake. In the case of the Chile earthquake, the amount of energy released during the quake, not the number of human deaths and damage to structures, earned it the title of greatest.
The epicenter of the earthquake (the point on the earth's surface directly above the focus of an earthquake) was 60 meters down below the ocean floor about 100 miles off the coast of Chile out in the Pacific. The nearby towns of Valdivia and Puerto Montt suffered devastating damage because of their closeness to the center of such a massive quake. The loss of human life was not as bad as it could have been because there were large foreshocks that sent people into the streets talking...... Read More
Mount Everest !
Mount Everest is so famous for being so high that you've probably heard of it before. It has been known the world over since the early 1950s when Sir Edmund Hillary and Tenzig Norgay first climbed to its awesome summit. Hillary surveyed Everest at the time and determined that it was 29,000 ft/8840m high - a figure amazingly close to the current reading of 29,035 ft/8850m, which was confirmed using radar and global positioning satellite (GPS) technology.......

Shroud of Turin
The
Shroud of Turin is an ancient yellowed linen cloth which bears the faded image
of a bearded man covered with blood stains which correspond to the wounds of
crucifixion. The Shroud has been kept in Turin, Italy for over 400 years but
has a history that can be traced to the sixth century with legends and folklore
going all the way back to First Century. Millions believe it is the actual burial
shroud of Jesus. National Geographic called it, "One of the most perplexing enigmas
of modern times". Time Magazine called it, "The Riddle of the Ages". The subject
is a fascinating blend of ancient history, sacred art, modern science and religious
tradition.......... Read More
