- Geology (Wikipedia.org)
Geology is the "science comprising the study of solid Earth, the rocks of which it is composed, and the processes by which they change. Geology can also refer generally to the study of the solid features of any celestial body (such as the geology of the Moon or Mars).Geology gives insight into the history of the Earth, as it provides the primary evidence for plate tectonics, the evolutionary history of life, and past climates."

- 08-04-03 Mars Rover Expedition (CNN)
"A NASA robot packed with eight cameras, geology instruments and super-rugged wheels roared into space on Tuesday, one of three missions headed to Mars this summer during the most favorable cosmic conditions in centuries."
"Their geologic studies, scheduled to last three months, are designed to find physical evidence of water activity on Mars from billions of years ago, when the planet was thought to have been wetter and warmer -- and possibly inhabited by microbes."
"Like surfers who have been waiting for the big wave, the spacecraft are riding to the red planet as Mars and Earth make their nearest pass to each other since prehistoric times."
"A closer approach won't take place until 2287, according to Sky & Telescope Magazine." 8-03
- 12-26-03 Beagle 2 Silent, But Orbiter Successful (CNN News)
"Even though a Mars probe has failed to signal it has landed, scientists at the European Space Agency said on Friday the primary mission goal to put a satellite in orbit around Mars was achieved."
"After a six-month, 100 million-km (63 million-mile) journey from Earth to look for signs of life on the planet, the Mars Express will circle the planet on an orbit between 250 km and 12,000 km."
"It will study the surface of the planet, its geology, its weather, and also analyse the atmosphere and its gravity." 12-03
- Evolution as Science (WhyFiles.org)
"By endorsing the theory that evolution through natural selection is an unproven theory, the elected board defied 150 years of science. It also raised doubts about a foundation of biology that has been resolved by the mounting evidence that all forms of life are interrelated."
"Evolution, the scientific study of the origins and development of life, has roots in geology, paleontology and field biology. It explains, for example, why so many insects but so few dinosaurs are alive today, or why certain flowers can only be pollinated by certain birds. It explains why microbes can become resistant to antibiotics, why cancers become resistant to anti-cancer drugs, and why the bones in a bat wing resemble the bones in your hand."
" 'A theory in science is not a hunch or "just a theory" as some say. It is an explanation built on multitudinous confirmed facts and the absence of incompatible facts.' Omitting evolution from biology, Singer pointed out, 'is comparable to leaving the U.S. Constitution out of civics lessons. Evolution is the framework that makes sense of the whole natural world...' "
" 'In the past 10 or 20 years, we have developed this completely independent record. Studies of the genome [an organism's genetic code] have in most cases completely confirmed...the relationships deduced from the fossil record.' "
- -06-21-12 Over Half a Million Wells in the U.S. Hold Waste With Unknown Risks (MSNBC News)
"Over the past several decades, U.S. industries have injected more than 30 trillion gallons of toxic liquid deep into the earth, using broad expanses of the nation's geology as an invisible dumping ground."
"No company would be allowed to pour such dangerous chemicals into the rivers or onto the soil. But until recently, scientists and environmental officials have assumed that deep layers of rock beneath the earth would safely entomb the waste for millenia."
"There are growing signs they were mistaken."
"Records from disparate corners of the United States show that wells drilled to bury this waste deep beneath the ground have repeatedly leaked, sending dangerous chemicals and waste gurgling to the surface or, on occasion, seeping into shallow aquifers that store a significant portion of the nation's drinking water."
" 'There is no certainty at all in any of this, and whoever tells you the opposite is not telling you the truth,' said Stefan Finsterle, a leading hydrogeologist at Lawrence Berkeley National Laboratory who specializes in understanding the properties of rock layers and modeling how fluid flows through them. 'You have changed the system with pressure and temperature and fracturing, so you don't know how it will behave.' "

"Scientists say they have dated an ancient crystal called a zircon to about 4.4 billion years, making it the earliest confirmed piece of the planet's crust. The findings -- the first to describe the zircon -- were published in the journal Nature Geoscience on Sunday." 03-14
