Sentences with phrase «chemical weathering process»

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..

Natural global warming is self - rectifying either by slow chemical weathering processes responsible for mineral sequestration of carbon or by gradual return of Earth's orbital parameters to what they were before the onset of global warming, thereby significantly reducing the amount of solar radiation reaching the Earth's surface.

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.

Together, physical and chemical weathering conspire to bring down mountains — and typically soak up CO2 in the process, but the overall magnitude of this climate - cooling effect has been long debated.

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.

Students become a part of the learning process with activities about ecosystems, body systems, physical and chemical changes, weather, Earth's crust, natural resources, and more!

The chemical process through which it's created allows the steel to sustain different types of weather and not crumble over time.

It is also possible for cold climates to increase chemical weathering in some ways, by lowering sea level to expose more land to erosion (though I'd guess this can also increase oxydation of C in sediments) and by supplying more sediments via glacial erosion for chemical weathering (of course, those sediments must make it to warmer conditions to make the process effective — downhill and downstream, or perhaps via pulsed ice ages -LRB-?)-RRB-.

Once the ice reaches the equator, the equilibrium climate is significantly colder than what would initiate melting at the equator, but if CO2 from geologic emissions build up (they would, but very slowly — geochemical processes provide a negative feedback by changing atmospheric CO2 in response to climate changes, but this is generally very slow, and thus can not prevent faster changes from faster external forcings) enough, it can initiate melting — what happens then is a runaway in the opposite direction (until the ice is completely gone — the extreme warmth and CO2 amount at that point, combined with left - over glacial debris available for chemical weathering, will draw CO2 out of the atmosphere, possibly allowing some ice to return).

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

Most have never heard of «chemical ice nucleation for weather modification», but patents exist for this process and the Chinese government has long since admitted to engineering frozen precipitation events.
