Sentences with phrase «chemical weathering of rocks»

This is balanced by an equivalent amount that is removed by chemical weathering of rocks.

Life on land, argues Schwartzman, has intensified the chemical weathering of rocks such that carbon dioxide has been removed from the atmosphere and the surface temperature of the Earth has remained cooler than if life had not been present - a kind of inverted global warming.

Working with Professors Joydip Mukhopadhyay and Gautam Ghosh and other colleagues from the Presidency University in Kolkata, India, the geologists found evidence for chemical weathering of rocks leading to soil formation that occurred in the presence of O2.

The mighty winds coming from the sea causes a big part to the displacement of minerals and the instinctive and chemical weathering of this rock formation.

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.

To understand weathering, water quality, and soil formation on Earth and Mars, look no further than associate professor of geoscience Elisabeth «Libby» Hausrath, who investigates chemical interactions between water and rocks as well as the plant and microbial influences on those reactions.

Plants are major contributors to the chemical weathering of continental rocks, a key process in the carbon cycle that regulates Earth's atmosphere and climate over millions of years.

This chemical weathering process is too slow to damp out shorter - term fluctuations, and there are some complexities — glaciation can enhance the mechanical erosion that provides surface area for chemical weathering (some of which may be realized after a time delay — ie when the subsequent warming occurs — dramatically snow in a Snowball Earth scenario, where the frigid conditions essentially shut down all chemical weathering, allowing CO2 to build up to the point where it thaws the equatorial region, at which point runaway albedo feedback drives the Earth into a carbonic acid sauna, which ends via rapid carbonate rock formation), while lower sea level may increase the oxidation of organic C in sediments but also provide more land surface for erosion... etc..

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.

For decades, it has been a given that heavy rainfall on steep mountain slopes is likely to chemically weather the exposed rock and precipitate a chemical reaction that ends with carbonate minerals on the ground and with less of the greenhouse gas carbon dioxide in the atmosphere.

«The rest is removed by slower processes that take up to several hundreds of thousands of years, including chemical weathering and rock formation.
