...these giant ones pose a threat to the entire planet. It was such an asteroid (or an equivalent-size comet) that many scientists believe caused the extinction of dinosaurs some 65 million years ago. The primary evidence, discovered by the late physicist Luis Alvarez and his son Walter, a geologist, is a layer of the element iridium laid down in sedimentary rock at about the time the giant reptiles disappeared. Iridium is rare on the earth's surface but more common in asteroids...
...eloquence. Edgar Mitchell, who flew to the moon aboard Apollo 14 in 1971, described the planet as "a sparkling blue-and-white jewel . . . laced with slowly swirling veils of white . . . like a small pearl in a thick sea of black mystery." Photos of the earth from space prompted geologist Preston Cloud to write, "Mother Earth will never seem the same again. No more can thinking people take this little planet . . . as an infinite theater of action and provider of resources for man, yielding new largesse to every demand without limit." That conclusion seems all the more imperative in the wake...
...example, was a considerably more destructive 8.1 seismic shock, yet fewer than 10,000 people died. Experts laid much of the blame for last week's shocking toll on the shoddy construction of the buildings in Armenia's cities and towns. According to Brian Tucker, acting state geologist of California who has visited Armenia, many buildings in the region are made of 8-in.-thick concrete slabs held together by metal hooks and mortar. Poorer Armenians, he says, tend to live in "very fragile, very deadly houses" made of unreinforced mud and rock. Yet geologists have long known that...
...centennial issue of the magazine, scientific symposiums and special exhibits in Washington, it can look back on a distinguished record of accomplishment. Since 1890 it has helped fund some 3,300 research projects and expeditions, from Commander Robert Peary's 1909 trek to the North Pole to Marine Geologist Robert Ballard's 1986 exploration of the wreck of the Titanic. The society was the first American publisher to set up a color photo lab (1920), the first to feature underwater color photographs (1927), and the first to print a hologram, or three-dimensional photograph...
...expedition mounted by the Woods Hole Oceanographic Institution and the French Institute for Research and Development of the Sea (IFREMER) found it broken into two pieces in the North Atlantic, about 350 miles southeast of Newfoundland, in 12,500 ft. of water. The following year, Woods Hole Marine Geologist Robert Ballard returned to probe inside the rusting hull and take photographs. But Ballard's crew left the ship and its artifacts undisturbed and urged others to do the same as a memorial to those who had died in the tragedy...
