Hot mantle drives elevation, volcanism along mid-ocean ridges
April 3, 2014
Using data from seismic waves, scientists have shown that the temperature deep in the Earth's mantle controls the elevation and volcanic activity along mid-ocean ridges, colossal mountain ranges that line the ocean floor. The findings, published this week in Science, bolster the idea that warm mantle plumes are responsible for "hot spot" volcanism, and shed new light on how temperature in the depths of the mantle influences the contours of the Earth's crust.
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.
