Saprolite is much like the weathered granite found on the flat areas surrounding the hard granite of Vedauwoo. “Our work shows that physical strain can no longer be ignored in studies of subsurface ...

This has important implications for the climate system, since chemical weathering of silicate rocks such as granite results in a drawdown of atmospheric CO2 and may therefore lead to global cooling.

Twain Harte rock in California is in a period of active exfoliation, sloughing sheets of granite in creaking, cracking, rock-flaking, dust-shedding, exhilarating glory. Explosive exfoliation ...

Research led by the University of Wyoming shows that physical weathering is far more important than previously recognized in the breakdown of rock in mountain landscapes. Because it is difficult ...

Weathering is the breakdown of rocks by carbonic acid, which forms when carbon dioxide in the air or soil dissolves into water. Weathering occurs naturally when rain falls on rocks, ...

A rock fell from Kuravan Hill, one of the two hills connecting the Idukki arch dam, early on Friday, because of rock weathering, a phenomenon that results in the rock falling on the foothill and ...
