The rocks on Earth are constantly changing due to many different processes. There are three main types of rock, with rocks changing between each type over millions of years. This rock recycling is a ...

A study published in Nature Geoscience reports new findings on the effects that erosion has on the carbon cycle. The study comes from a group of researchers led by Aaron Bufe and Niels Hovius of the ...

Introduction Have you ever visited a canyon or cave and wondered how those formations came to be? Or observed smooth stones by a river or beach? These results are due to a process called weathering.

The Earth’s natural geological weathering cycle – in which rocks erode and make their way to the sea – traps CO2. But that can take millions of years. Scientists want to accelerate the process to ...

Weathering is key Ecosystems need nitrogen and other nutrients to absorb carbon dioxide pollution, and there is a limited amount of it available from plants and soils. If a large amount of nitrogen ...

Last week, a group of geoengineers met in Hamburg to discuss what on the face of it sounds like a very attractive idea: to soak up anthropogenic carbon emissions using only rocks and water. In ...
