potholer54 | How did rocks become knobbly and bumpy? – a basic geology guide. @potholer54 | Uploaded November 2022 | Updated October 2024, 5 hours ago.
I am a former geologist turned science journalist, and this video explains the things that used to mystify me when I first became a geology student -- How mud, sand and silt that lay dozily on the sea bed, could rise up and create the extraordinary landforms we see all around us.
Sorry there are no references in this video, as is usual with my videos. That's because most of this is pretty basic textbook stuff. If I've made any mistakes, please do send in corrections, which I'll list here.
CORRECTIONS:
15:56 -- I said "calcium carbonate is a strong alkali". One poster pointed out that it is a 'moderately strong alkali.' Concentration is dependent on the chemical's dissociation constant, Ka. The poster writes: "CaCO3 has a pKa of 9, it would need to be at least 14 to be considered strong."
DONATIONS:
To support this channel, please don't send me money. I prefer people donate to a charity I support (shown at the end of this video, and donations page at the bottom of this text.)
It's called Health in Harmony. See my video youtube.com/watch?v=j9-GRugP9pU for details.
The charity funds hospitals and affordable health care to villages on the edges of national parks, in return for a pledge not to cut down trees. The pledges are monitored, and the result has been a dramatic decrease in deforestation rates and an increase in the health of the local population.
Patients -- mostly from farming families -- can pay for their subsidised treatment with tree saplings or manure. So for them, treatment is essentially free.
The manure goes to organic farms that HiH is encouraging, as it teaches local farmers how to farm organically rather than slash-and-burn the forest.
As for the tree saplings, HiH volunteers plant these in areas of forest that have been illegally cut. This restores the forest, and HiH receives money for this from people and companies who pay for carbon credits. That money goes towards paying doctors, nurses, dentists, and and keeps the clinics running.
Independent studies have shown that HiH's operations in Borneo have increased the health of the population, improved agriculture and reduced illegal logging. replanted areas of the forest have brought back ecosystems and animals that had suffered from deforestation.
But more money is always needed, to keep the hospitals going and to expand into new areas. Thanks to your generous contributions, the HiH founders are spreading the idea to other parts of the world.

MONETISATION:
I monetised the channel last year and tried to make Health in Harmony the beneficiary of ad revenue. Unfortunately, after a month of red tape, we discovered this couldn't be done because the charity's address is different to the registered address of this channel. So I have switched off monetisation for my videos, preferring not to have annoying ads. I don't want to be the beneficiary of ad revenue and have my motives compromised.
However, as an experiment I am monetising this video, to see how the system works, and how much money can be made. I'll transfer the proceeds directly to HiH. We'll see how it goes, but please keep your personal donations to HiH going -- many thanks.
