The Critical Zone encompasses the near‐surface environment where rock, soil, water, air and biota interact in a dynamic equilibrium that drives essential geochemical cycles. Research in this area ...

Sandstone landscapes, with their intricate forms and textures, offer an excellent window into the processes that shape our planet’s surface. The evolution of these formations is governed by a ...

Rocks are not eternal. Even the tallest mountain will eventually dissolve and disintegrate. Geologists call this process “weathering.” It sounds harmless enough, but weathering is one of the most ...

Brad Carr, a UW associate research scientist in geology and geophysics, uses the Geoprobe instrument to sample the subsurface in the foothills of the southern Sierra Nevada in California. Carr ...

CAMBRIDGE, Mass., Nov. 7, 2007 — Researchers at Harvard University and Pennsylvania State University have invented a technology, inspired by nature, to reduce the accumulation of atmospheric carbon ...

An assemblage of highly weathered bedrock forms is reported from an upland ridge at 500 m a.s.l. near Cory Glacier on the southeastern coast of Ellesmere Island. Examples of grus accumulations, tafoni ...

Researchers from the Institute of Applied Ecology of the Chinese Academy of Sciences (CAS) have conducted an ecosystem-wide ...

The Science Behind River Downcutting The water pressure of a river can cut deep into a riverbed. Sediments from the riverbed are carried downstream, creating a deep, narrow channel. This process, ...

If a rock particle is loosened, chemically or mechanically, but remains there itself, it is called weathering. Once the rock particle starts moving by agents such as water, snow, wind, waves and ...

The natural rock weathering process, while effective in breaking down carbon and storing it within rocks over thousands of years, may not provide the immediate solution to combat climate change. With ...

Scientists have discovered that chemical weathering, a process in which carbon dioxide breaks down rocks and then gets trapped in sediment, can happen at a much faster rate than scientists previously ...
