Chemical Weathering Processes

With physical weathering understood, let's talk about chemical weathering. The minerals found in rocks can sometimes undergo specific chemical reactions to modify the composition of the rock, and this is called chemical weathering. These reactions are typically either acid-base reactions or redox reactions. Let's get a closer look at the chemistry now!

Fascinating how complex even what appears to be 'simple' processes of nature. The more we explore and look into the world around us, the more we find how complex it is.

Dear Dr. Dave: Please read: I love your stuff. Look for this video: Data shows there’s no climate catastrophe looming - climatologist Dr J Christy debunks the narrative Can you please debunk Dr. J Christy? He's a Nobel prize winner who is at the forefront of climate denial. Also, you might look into John Coleman. Thank you. This is so important. Please help.

[@Marco-it2mr]

Christy is not a Nobelprize winner. He *did* contribute a small part to an IPCC report.

Your content never fail to entertain and educate. I have been suggesting one specific topic to you for some time now as some other guys. Can you make a dedicated video on the origin of life ?. That would be very valuable resource for both education to combat false information

[@ProfessorDaveExplains]

I've been thinking about doing a series on that.

[@waelfadlallah8939]

​@@ProfessorDaveExplainssounds difficult and tricky to do. And may also open a whole new unending arguments!

[@pansepot1490]

For my part, I consider prof. Dave’s videos debunking James Tour an excellent overview of origin of life research. I had to watch them several times because tbh most of the organic chemistry went over my head but at least I was able to grasp the concepts and as said above, now I have a tolerably comprehensive overview of the knowledge scientists have at present. I am sure that a focused tutorial would be much easier to digest, still, I thought I mentioned it in case someone is interested.

[@glennpearson9348]

Having grown up in Texas, I've driven around west Texas, New Mexico, and Arizona, noting these brightly red-colored formations protruding up from the ground. Some of these formations are over one-hundred feet tall. The young Earth creation crowd would have you believe that these formations appeared sometime in the last 6,000 years - about when one can calculate from the Bible that the Earth was first created. However, as any geologist worth their salt will explain, these formations resulted not from uplift forces, but from weathering of the ground around them over millions of years. Neat stuff, Professor Dave. Like many of your other series, this one, too, it panning out to be quite a fun journey down the geologic trail.

What is the chemical reaction that breaks down Granitoid rocks into Grus? Is it the breakdown of feldspar Into clay or the breakdown of quartz?

[@umershaikh7179]

[@dukecity7688]

So, this is not erosion? I am not swift. I do want to understand.

[@Marco-it2mr]

Weathering is just small parts of rocks breaking off of the larger part. Chemical weathering means this "breaking off" is due to a chemical reaction - this is in contrast to mechanical weathering, where some physical process results in breaking off of (small) parts of the rock. Erosion is the process by which these small parts are then moved away from their original location.

[@richardfurness7556]

To add to Marco's reply, erosion requires an agent such as water, ice or wind to transport the weathered material from its original location. It's this combination that shapes the landscape. For example, the rocks and boulders a fast-flowing river can carry downstream will deepen its bed and wear away the sides of its channel, forming a valley. Look at any video of a flash flood to see just how much material the water can pick up.

[@dukecity7688]

@@richardfurness7556 Ah, now I see it clearly. Thanks friend.

[@SuperAwesomestness]

physical weathering would be like wind blowing a pile of sugar, but chemical weathering is more like dissolving it in water (the pile's gone, but you have sweet water). With all the chemicals the world has to offer, and interactions between them, chemical weathering can produce alot more results and take varying amounts of time.

is lichen eating away a rock be deem chemical weathering or biological weathering?

[@KATTTTJESSICA-zh4by]

wtf is a linchen

[@thureintun1687]

@@KATTTTJESSICA-zh4by it's refer to any lifeforms that form form symbiosis between fungus and algae or cyanobacteria(blue green algae). Some of them are beautiful, with my favorite being Xanthoria elegans, a species of extremely cold hardy lichen that can survive in some of the harshest environments on earth. Even in space simulation, it actually able to recover from exposure of doses of radiation, vacuum. It got ashade of bright orange color all over. Id say lichens are one of the most colourful lifeforms, for sure. Orange, limegreen, white, black, gray, you named it, in all sort of shapes/forms like leaflike, rocklike, jellylike,and even maplike(literally called "map lichen")! lol More over, new species of lichens are still uncovered all the time, some of which are considerably extremophlic, like the above. Due to their ability to tolerate some of the most severe and barren regions on earth, such of antarctic valleys(one of the driest places), some experts hav said lichens(prob. genetically manipulated) could well be among the pioneer species in our (future)attempts at bio/terraforming Mars and beyond. If you know even a little bit about these organisms, you can see why they said that. I mean it sorto like is a nature's way of slapping together two hardiest forms of life, fungi and algae, and make the choosen two work together for their own benefits! How cool is that? lol No wonder lichens turned out to be one of my favourite forms of life in nature. And note too that some symbiotic partners in them fix nitrogen too. Famous examples being species of genus Nostoc. All of this make lichens among the most important organisms in earth's ecosystem, esp. when it comes to colonising newly disturbed lands and such. Also very important in providing food source up and along the trophic level

Dave your bread is way yoo under proofed. I dont even know how you get it like that. Unbelievable.

[@SuperAwesomestness]

I'm sure you meant beard, but now I'm curious what proofed bread would be like. Alcoholic bread? Yeast is used for bread and beer, but I don't know if alcoholic bread is even possible.

[@JosefDerKaiser]

@@SuperAwesomestness I did mean bread. Proofing is the step you take to let the bread rise before you throw it in the oven. If you under-proof, you can get huge steam bubbles surrounded by thick, dense doughy bread, that looks kind of like the thumbnail on the inside.

Can you explain the meaning of crystallization temperature 00:22 ? And also @1:46 you said in the atmosphere water reacts with dissolved CO2, how come CO2 is dissolved when it should be obviously in the gaseous form in the atmosphere ?

[@HugoFilho.]

Crystalization temperature is the temperature that a mineral crystalizes from magma. CO2 is dissolved because it is water soluble to some extent
