During the Ordovician period, the concentration of carbon dioxide in Earth's atmosphere was about eight times higher than today. It has been hard to explain why the climate cooled and why the ...

It rains a lot here in the wettest place on earth. Months and months of steady, unrelenting rain, falling on our rooftops, falling on our hills. I’ve imagined it as many things – a singer of lullabies ...

A new study published in the journal Nature has overturned the view that natural rock weathering acts as a CO2 sink, indicating instead that this can also act as a large carbon dioxide source, ...

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 ...

High erosion in southern France exposes these sedimentary rocks to weathering, releasing carbon dioxide as the ancient organic carbon breaks down. The Earth’s stones contain a large amount of carbon ...

A new University of Washington study shows that the textbook understanding of global chemical weathering -- in which rocks are dissolved, washed down rivers and eventually end up on the ocean floor to ...

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 to ...

Not all nitrogen comes from the atmosphere Up to a quarter of nitrogen on Earth comes from rocks Discovery could greatly improve climate change projections and focus carbon sequestration efforts For ...

"He was searching for rocks an entire life Never to be satisfied. In the end he got a last stone That should satisfy him." Graveyards have a lot to do with geology, from the rocks used for gravestones ...
