Impact from the Deep

A new view on the Permian Extinction.

Strangling heat and gases emanating from the earth and sea, not asteroids, most likely caused several ancient mass extinctions. Could the same killer-greenhouse conditions build once again?

A cool early Earth? (Scientific American, 2005)

Posted by arleneteng on February 1, 2010 at 11:08 AM

by John. W. Valley


 

The textbook view that the earth spent its first half a billion years drenched in magma could be wrong. The surface may have cooled quickly—with oceans, nascent continents and the opportunity for life to form much earlier.


In its infancy, beginning about 4.5 billion years ago, the earth glowed like a faint star. Incandescent...

IUGS Special Publication 273 - Myth and Geology


This book is the first peer-reviewed collection of papers focusing on the potential of myth storylines to yield data and lessons that are of value to the geological sciences. Building on the nascent discipline of geomythology, scientists and scholars from a variety of disciplines have contributed to this volume. The geological hazards (such as earthquakes, tsunamis, ...

Evolution and the Fossil Record

Posted by arleneteng on December 2, 2009 at 4:51 AM

by John Pojeta, Jr. and Dale A. Springer


Evolution is one of the fundamental underlying concepts of science. This powerful theory explains such phenomena as the history of life as preserved in the fossil record; the genetic, molecular and physical similarities and differences among organisms; and the geographic distribution of organisms today and in the past. Indeed, evolution forms the foundation of modern biology and p...

Origin and Evolution of Earth (National Academy of Sciences, 2008)

Posted by arleneteng on November 30, 2009 at 6:38 AM

Questions about the origins and nature of Earth have long preoccupied human thought and the scientific endeavor. Deciphering the planet’s history and processes could improve the ability to predict catastrophes like earthquakes and volcanoes, to manage Earth’s resources, and to anticipate changes in climate and geologic processes. This report captures, in a series of questions, the essential scientific chall...

What do we know about the origin of the earth's oceans? (Scientific American, 1999)

Posted by arleneteng on November 30, 2009 at 6:34 AM

by Tobias C. Owen, Institute for Astronomy in Honolulu, Hawaii

This is a very good question, because we do not yet have an answer that everyone accepts.

The origin of the oceans goes back to the time of the earth's formation 4.6 billion years ago, when our planet was forming through the accumulation of smaller objects, called planetesimials. There are basically three possible sources f...

In the beginning, there was Ur (Endeavors Magazine, 1997)

Posted by arleneteng on November 30, 2009 at 6:21 AM

by Elizabeth Zubritsky 

As John Rogers sees it, three billion years is as far back as you can go in studying continents. Before that, they didn't exist -- not by his definition.

Traditionally, geologists determined the age of a continent based on the oldest exposed rock, which is some variety of granite. Because granites constitute the foundations of continents, geologists assumed that any granite found must date ba...

A prehistoric lahar-dammed lake and eruption of Mount Pinatubo described in a Philippine aborigine legend

Posted by arleneteng on August 7, 2009 at 12:06 AM

by Kelvin S. Rodolfo and Jesse V. Umbal


Abstract. The prehistoric eruptions of Mount Pinatubo have followed a cycle: centuries of repose terminated by a caldera-forming eruption with large pyroclastic flows; a post-eruption aftermath of rain-triggered lahars in surrounding drainages and dome-building that fills the caldera; and then another long quiescent period. During and after the eruptions laha...

Plate tectonics started over 4 billion years ago, geochemists report

Posted by arleneteng on July 14, 2009 at 6:43 AM

by Stuart Wolpert


A new picture of the early Earth is emerging, including the surprising finding that plate tectonics may have started more than 4 billion years ago -- much earlier than scientists had believed, according to new research by UCLA geochemists reported Nov. 27 in the journal Nature.


"We are proposing that there was plate-t...

A new picture of the early Earth

Posted by arleneteng on July 14, 2009 at 6:41 AM

by Kenneth Chang


The first 700 million years of Earth’s 4.5-billion-year existence are known as the Hadean period, after Hades, or, to

shed the ancient Greek name, Hell.


That name seemed to fit with the common perception that the young Earth was a hot, dry, desolate landscape interspersed with seas...

Life in extreme environments

Posted by arleneteng on July 14, 2009 at 6:38 AM

by Lynn J. Rothschild & Rocco L. Mancinelli


Each recent report of liquid water existing elsewhere in the Solar System has reverberated through the international press and excited the imagination of humankind. Why? Because in the past few decades we have come to realize that where there is liquid water on Earth, virtually no matter what the physical conditions, there is life. What we previously though...

Hutton's geology

Posted by dog-upb on April 27, 2009 at 11:39 PM

 

No vestige of a beginning -- no prospect of an end.


Geologists are engaged on the business of reconstructing the earth's past and determining the agents of geological change. The only documentary evidence of the earth's origins and ancient past, and of the agents that had caused change, available to Hutton was the book of Genesis, and he had skeptically put it aside, along with miracle...

How rocks evolve (Economist.com, 13 Nov 2008)

Posted by arleneteng on April 14, 2009 at 9:42 AM

It is not just living organisms that evolve. Minerals do too, and much of their diversity has arisen in tandem with the evolution of life.


Evolution has come a long way since Charles Darwin?s time. Today it is not only animals and plants that are seen as having evolved over time, but also things that involve the hand of humans, like architecture, music, car design and even governments. Now rocks, too, see...
