Why a Rocky Mountain high?

A University of Utah study shows how various regions of North America are kept afloat by heat within Earth's rocky crust, and how much of the continent would sink beneath sea level if not for heat that makes rock buoyant. Of coastal cities, New York City would sit 1,427 feet under the Atlantic, Boston would be 1,823 feet deep, Miami would reside 2,410 feet undersea and Los Angeles would rest 3,756 feet beneath the Pacific.

   12-19-2007 · EurekAlert!
   UC-Davis researchers have dated the earliest step in the formation of the solar system -- when microscopic interstellar dust coalesced into mountain-sized chunks of rock -- to 4,568 million years ago, within a range of about 2,080,000 years.

5. Midges send undeniable message -- Planet is warming
   12-11-2006 · EurekAlert!
   Small insects that inhabit some of the most remote parts of the United States are sending a strong message about climate change. New research suggests that changes in midge communities in some of these areas provide additional evidence that the globe is indeed getting warmer. Researchers created a history of changing midge communities for six remote mountain lakes in the western United States.

7. Plate tectonics may take a break
   01-03-2008 · EurekAlert!
   Plate tectonics, the geologic process responsible for creating the Earth's continents, mountain ranges, and ocean basins, may be an on-again, off-again affair. Scientists have assumed that the shifting of crustal plates has been slow but continuous over most of the Earth's history, but a new study from researchers at the Carnegie Institution suggests that plate tectonics may have ground to a halt at least once in our planet's history -- and may do so again.

8. How trees manage water in arid environments
   01-03-2007 · EurekAlert!
   Mountain-top forests in Arizona have survived a three-year period of extreme drought. These conifers have evolved the ability to "turn themselves on" whenever water is available, both in winter when such trees elsewhere are dormant and in summer when sudden heavy rains must be exploited quickly. When water is scarce, the trees greatly reduce their activity.

9. Investigating Life in Extreme Environments report gives hints on facts of life
   07-04-2007 · EurekAlert!
   From the deepest seafloor to the highest mountain, from the hottest region to the cold Antarctic plateau, environments labeled as extreme are numerous on Earth and they present a wide variety of features and characteristics. Investigating life processes in extreme environments not only can provide hints on how life first appeared and survived on Earth (as early earth was an extreme environment) but it can also give indication for the search for life on other planets.
