But new measurements from steep mountaintops in New Zealand show that rock can transform into soil more than twice as fast as previously believed possible. The findings were published Jan. 16 in the early online edition of Science. "Some previous work had argued that there were limits to soil production," said first author Isaac Larsen, who did the work as part of his doctoral research in Earth sciences at the...

Some of the steepest mountain slopes in the world got that way because of the interplay between terrain uplift associated with plate tectonics and powerful streams cutting into hillsides, leading to erosion in the form of large landslides, new research shows. The work, presented online May 27 in Nature Geoscience, shows that once the angle of a slope exceeds 30 degrees — whether from uplift, a rushing stream carving away the bottom of the slope or a combination of the two —...
