Abstract
Quartz grains altered by cosmic rays are forcing geologists to reevaluate which forces shape landscapes and how fast they operate. A handful of researchers have begun using cosmogenic nuclides to study long-term erosion rates, a tool that has enabled them to paint a portrait of landscape formation with previously unparalleled resolution. Barely out of its infancy, this technology has already spawned a slew of applications, from examining the sustainability of agricultural practices to decoding signals of global climate change.Keywords
