All rocks are made up ofminerals, crystalline structures made up ...

Weathering refers to the decomposition of rock due to physical, chemical or biological forces.Rocks that contain iron are susceptible to chemical
Weathering processes are of three main types: mechanical, organic and chemical weathering. Mechanical or Physical Weathering Mechanical weathering is alsoknown as physical weathering. Mechanical weathering is the physical breakdown of rocks into smaller and smaller pieces. One of the most common mechanical...
Despite deriving from different sources, all types of erosion fall into one umbrella category. Weathering, however, takes place in two distinct processes, classifying as chemical or mechanical. Chemical weathering occurs when rocks undergo a change in chemical composition. Mechanical weathering refers to...
Weathering The Earth's surface is shaped via weathering, from either physical, chemical or biological factors. These factors can act separately or as a combined force. Physical weathering causes the disintegration of rock material without the presence of decay. Thermal expansion–the alternating process...

CO 2-consumption by chemical weathering of silicates and resulting silicate/carbonate weathering ratios influences long-term climate changes. However, little is known of the spatial extension of highly active weathering regions and their proportion of global CO 2-consumption. As those regions may be ...
The rest is removed by slower processes that take up to several hundreds of thousands of years, including chemical weathering and rock formation. This means that once in the atmosphere, carbon dioxide can continue to affect climate for thousands of years. Methane, by contrast, is mostly removed...
