Continents Loss to Oceans Boosts Staying Power
April 1, 2008
New research in the Proceedings of the National Academy of Science finds that the geological staying power of continents comes partly from their losing battle with the Earth's oceans over magnesium. Continents lose more than 20 percent of their initial mass to chemical weathering, but they ultimately gain because the lighter, silicon-rich rock that's left behind is more buoyant and less prone to being subducted and returned to the mantle.
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2016, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
