24 kwi 2024 · Weathering is the breaking down or dissolving of rocks and minerals on Earth's surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion.
17 gru 2019 · Nature Communications - Carbonate weathering captures CO2 and represents a large sink of terrestrial carbon that is threatened by climate and land-use change. Here the authors build a model...
1 lut 2022 · Chemical weathering of Ca-silicate rocks is thought to control the long-term global climate by drawing down atmospheric CO 2 concentration via precipitation of carbonate in the ocean sediments. (1) CO 2 + CaSiO 3 → CaCO 3 + SiO 2. This process could storage atmospheric CO 2 for millions of years (0.5 to 1 Myr time scale).
21 lut 2022 · The continental weathering process is driven by environmental factors such as changes in temperature, moisture, and CO 2 concentration, which can have natural (climate) or anthropogenic (land-use) origins.
Chemical weathering is the main process that drives the carbonate-silicate geochemical cycle. Figure 2 shows how this cycle controls the long term transformation of silicate rocks into carbonate rocks over geologic time.
20 lis 2019 · Carbonate weathering is not only important as a major CO 2 consumption process, it is also a dominant control in determining water quality. Overall, this study urgently calls for more investigation on carbonate weathering.
