Sentences with phrase «natural weathering of rocks»

By comparison, the natural weathering of rocks results in about 10 Bq of radioactive potassium - 40 making it into each litre of seawater.

Not exact matches

For example, rock records of an isotope of strontium — 87Sr — seem to show an increase in so - called chemical weathering, or weathering that is not simply the result of rain or other natural but not life - related processes.

As part of her Camden Arts Centre Ceramics Fellowship in 2013, Cummings created a temporary work in the garden exploring the natural formation of clay through the weathering of rocks.

And outside the energy sector: Biological CO2 capture via photosynthesis and storage in ecosystems (e.g. forests, grasslands, wetlands, oceans) and / or agricultural lands (e.g. soils, biomass); and chemical CO2 capture via enhanced weathering of rocks that natural react (albeit quite slowly) with CO2 in the air.

But it was always at a rate that could easily be accommodated by natural feedback processes if CO2 levels got too high — usually in the form of increased rock weathering through an acceleration of the hydrological cycle.

The natural acceleration of the the hydrological cycle that occurs when CO2 levels rise, increases rock weathering and is the key to the negative feedback that eventually pulls the atmospheric CO2 levels back down.

The primary natural way the Earth removes carbon dioxide from the atmopshere is through rock weathering, which pulls the CO2 from the air and eventually sequesters it in limestone at the bottom of the ocean.

Long - term Cenozoic temperature trends, the warming up to about 50 Myr before present (BP) and subsequent long - term cooling, are likely to be, at least in large part, a result of the changing natural source of atmospheric CO2, which is volcanic emissions that occur mainly at continental margins due to plate tectonics (popularly «continental drift»); tectonic activity also affects the weathering sink for CO2 by exposing fresh rock.

«The natural pH of the ocean is determined by a need to balance the deposition and burial of CaCO3 on the sea floor against the influx of Ca2 + and CO2 − 3 into the ocean from dissolving rocks on land, called weathering.
