Continental rift valleys are huge fractures on the surface of the planet that progressively break continental plates with the eventual development of new oceans. The African rift valley between Ethiopia and Kenya is a classical ...
Scientists seeking to understand Earth's inner clockwork have deployed armies of sensors listening for signs of slips, rumbles, exhales and other disturbances emanating from the planet's deepest faults to its tallest volcanoes. ...
The string of volcanoes in the Cascades Arc, ranging from California's Mt. Lassen in the south to Washington's Mt. Baker in the north, have been studied by geologists and volcanologists for over a century. Spurred on by spectacular ...
Glaciers that drain ice sheets such as Antarctica or Greenland often flow into the ocean, ending in near-vertical cliffs. As the glacier flows into the sea, chunks of the ice break off in calving events. Although much calving ...
With natural gas booming across the Front Range, drilling rigs may operate within feet from cattle farms. That shared land use can confound attempts to understand trends in methane, a greenhouse gas and air pollutant—the ...
For the first time ever, researchers have been able to peek deep into the mantle of the Earth under an ultraslow mid-ocean ridge, where they have been able to observe mantle melting and growth of the Earth's crust.
Terrestrial water storage (TWS) includes all phases of water over land (e.g., surface and groundwater, snow, etc.) and comprises an important freshwater resource. It is a critical component of the terrestrial water cycle, ...
