What is Biogeochemistry?

duncan61 wrote:
Biogeochemistry is a relatively new scientific discipline that explores the physical, chemical, biological, and geological processes and reactions that govern the composition of and changes to the natural environment. In particular, biogeochemistry studies the cycles of crucial elements, such as carbon and nitrogen, and their interactions with other substances and organisms as they move through Earth's atmosphere, hydrosphere (water and ice), biosphere (life), and lithosphere (rock). The field focuses especially on the diverse and interlinked chemical cycles that are either driven by or have an impact on biological activity, in particular carbon, nitrogen, sulfur, and phosphorus.

A prime example is carbon, the building block of life on Earth, and the planet-encompassing carbon cycle. Photosynthetic plants on land and sea take carbon dioxide (a form of inorganic carbon) from the atmosphere and convert it into the organic forms of carbon they need to live and grow. Animals that consume the plants incorporate the organic carbon into their own bodies.

Microbes eventually decompose dead plants and animals, and their carbon is recycled into soils and groundwater or swept into the oceans, where it becomes available to microbes and phytoplankton at the base of the marine food chain or it sinks and is buried in seafloor sediments. Over millions of years, carbon that is buried on land or at the bottom of the ocean becomes incorporated into rocks or hydrocarbons, where it might remain for tens to hundreds of millions of years. Ultimately, volcanoes return some of this carbon to the air as gas, where its heat-trapping properties affect Earth's climate, or else the rocks containing carbon are uplifted onto continents and gradually weathered, releasing their carbon back to the environment and making it available to organisms once again.

Why is it Important?
In a sense, chemicals are like currency, and biogeochemistry is the study of the nearly limitless "transactions" that drive the entire planetary system, including life on Earth. Understanding these fundamental processes provides crucial insights into how life formed, has evolved, is sustained, and is threatened on our planet, and how the various chemical cycles govern and regulate Earth's climate and environment.

Such knowledge enhances our ability to find ways to adapt to climate change and its impacts, enhance agriculture and food production, manage fisheries, mitigate pollution, develop alternative and renewable energy, prevent diseases and create new drugs, and spur innovations that can drive economic prosperity and improve our quality of life.

After nine years of... posting, maybe you should compile some of your "greatest hits".

IBdaMann and Into the Night, I encourage both of you to find the BEST of your past posts and compile them so they can all be seen together in one place.

The posts where you make the most convincing argument to prove your... whatever your point is.

I hope that they won't all be one liners like

Define your terms.

There is no such thing as 'climate change'.

Science is not...

You are a liar.

You are a moron.

You don't even know what science is.

Stop spamming.

Surely, after eight or nine years, you have posted something that is of lasting value and you are proud to share it again.

I mean, "Biogeochemistry debunked", for example. So much to be learned from it.

Please put together an album of your greatest hits, so people will have some idea what the eff you are even trying to say.

Or at least prove that you HAVE something to say.

Other than trolling other people's posts on threads you don't even understand.

Well, it wouldn't have to go down much in pH to cross that threshold.

"Rain is naturally acidic" - Into the Night

As they say, even a broken clock is right twice a day.

Yes, it is. Natural rainfall, NOT impacted by H2SO4 or HNO3, is acidic.

At 400 ppm CO2, rainwater has a pH about 5.6

Im a BM wrote:
The pH of rainwater can be calculated using Henry's Law.

Im a BM wrote:
If the concentration of CO2 doubled to 800 ppm, the pH of rainwater would be about 5.3

Im a BM wrote:
That is because carbon dioxide dissolves in water, and some of it becomes carbonic acid (e.g. ocean "acidification")

Im a BM wrote:
In contrast, sea water at pH 8.2, is 1.2 pH units on the alkaline side of neutral.

Im a BM wrote:
Just as atmospheric carbon dioxide dissolves in fresh water to take the pH down to 5.6, it dissolves in sea water. Increased input of carbonic acid to the sea has taken the pH down from about 8.2 to 8.2

Im a BM wrote:
Increased concentration of carbon dioxide in the atmosphere has caused the "naturally acidic" pH of rain to decrease slightly.

However, this is not what is called "acid rain" (acidic deposition)

"Acid rain" is when sulfuric acid and nitric acid, from human activity, bring the pH down to 4 or even 3.

"Acid fog" can have pH as low as 2.
