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 ...

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 ...

Reverse weathering is one of the ocean's most important yet least understood geochemical processes. During this natural process, dissolved minerals and chemicals combine to form new clay minerals in ...
