- We've been focusing on the layers of the Earth for a while now, so let's start looking at rocks themselves. Rocks are assemblages of minerals. So what's a mineral? What are their properties? What kinds of bonds occur within them? Let's take a look!

"The precise definition of a mineral depends on who you ask"
I hear DEA agent Hank Schrader is a good authority on minerals.
Minerals Marie
Great video, I love how y’all are including chemistry in this. Minerals are such a good, physical example for learners of all ages to conceptualize chemical bonding
I live in the Mojave desert and have a huge collection of rocks I know nothing about. So many of the hippies around here seem to think my collection is vibrant and spiritual but I just think they need to calm down with the hallucinogens and just realize they just look pretty. I’m glad you’re doing this series so I can actually know what I’m looking at.
pretty looking things always have to have a deeper meaning to some people and make their own placebo, but i also just collect rocks because they're pretty. Used to collect tens of glassy sand "lava rocks" that I found on a red sand running field.
some people are happy with the simplest and dumbest explanations for the things they don't understand, instead of learning from people who understand
Oy, I dunno whether to love or hate Prof. Dave's videos; they're so well done that it's all too easy to get distracted from other things I should be doing :P
Professor Dave Rocks!! Horrible pun. . . lmao
I think it was a good pun haha :)
The McEwens will be here all week. Don't forget to tip your server and try the veal!!!
They are not rocks they are minerals
@@muskelversagen professor Dave is not a mineral. He rocks.
@@muskelversagen o
Great video as always
What do you call friendships that form based on a shared love of heavy music?
Metallic bonds!....... yeah, I'll see myself out.
🔥🔥
Yess excited for this mineral series
Thanks Prof. Dave, you rock!
I love your videos, very easy to follow, continue man!
This is fascinating, thank~you!
Love this! Thank you for the great videos
That was excellent 👌 thank you Dave
Good explanation for beginners. Because there are far too few who really deal with something like this intensively.
amazing, thank you!!
Very educational 🥰
I Love your videos
Excellent ❤
Thank you
Came to insult flat earth. Stayed for the amazing science. This is in my top 5 favorite sciences
@@entertainingviralvideos yo I get it that we can't trust a single thing the government tells us. And I accept there is a 1% chance that you are right. Like there is a 1% chance the mormans are right. Or that the christian devil made dinosaur bones to trick people into not believing in god.
U don't have to believe what I do. And I don't care what you believe . Find a hobby. All that energy tracking down anti flat earth comments could be spent changing the world for the better
@@entertainingviralvideos also I don't think you fully understand what you're saying. Gravity is an accepted anomaly. Might even suggest parallel dimensions. Never mind. You're not here for the science
That was intresting, hurry up with the next video.
When geologists stare at cleavage, they go rock hard.
Nice one! Now I’ll have to go get my old mineral collection out of storage!
Yeah right, you won't
@@curiodyssey3867 ?
I have so many
Please do a video on terryology
This is what probably Dr. James Tour talks about Dave having some good videos too.
What's the purpose for rocks and minerals? I know some can be grinded down to gunpowder, explosive, or salt. After that what are, what are rocks and minerals good for?
I love your intro
3:27 arent covalent bonds weaker than ionic? In ionic complete tranfer of electron takes place while covalent involves sharing of electron so electrostatic forces will be dominating in ionic bonds
Very interesting and informative
Nice
Do quarks have a shape?
So then what is an Opal, when they are not a mineral?
Aren't ionic bonds typically stronger than covalent bonds?
No.
@@marknieuweboer8099 I recall that my gen chem course in university mentioned this and all sources I can find with a quick google search agree with me. Please elaborate if you can.
@@jagmeemees Here's one answer I found on quora:
"What bond is stronger, covalent or ionic?"
"There is no general answer to your question.
Some ionic bonds are stronger and some covalent bonds are stronger.
• lonic bonds are stronger than covalent bonds in vacuum (vacuum is a space in which there is no matter including air).
• In biological conditions (e.g. : living cells) which are often aqueous (involves water) covalent bonds are stronger than ionic bonds.
Why? because water dissociate ionic compounds (e.g.: dissociation of salt in
water)."
Interestingly I found sources that contradict each other. I'll give you my first impression; right now I don't have the time to check carefully.
It seems to matter if we're talking molecules or the atoms a single molecule consists of. Groups of molecules with ionic bonds are stronger, in the sense that more force is needed to tear them apart. But it takes more force to pull a molecule with a covalent bond apart than to do it with a molecule with atoms apart. The atoms of table salt will roam freely in water when you put them into that. The atoms of oxygen won't.
So I change my previous answer: it depends on your criterium.
Thanks, I like this.
Why are the igneous rocks are Solidificiton
Why 😢😢😢😢😢
I don't know
James D. Dana wrote a book about science and the Bible. It’s a pretty interesting read.

Minerals are defined as: that of which a geologist can see.
Thus they will not see the wooden baseball bat in my other hand
"they're not rocks, marie. they're minerals"
What pretty colours. Perhaps they have mystical properties. 😂😂😂
Minerals are very important in the world
Please elucidate us on the reasons/ proof that crystal growth does not occur due to some inherent proto-intelligence on sub-atomic energy level. How about autocatalysis? tnk you.
Autocatalysis? Crystal growth is not a chemical reaction.
@@ProfessorDaveExplains I did not say that. My question is why any of these phenomena (that exhibit some ' innately driven' growth/movement/spatial arrangement like crystal growth, chemical autocatalysis, spontaneous folding of proteins, etc) cannot be explained by the presence of some inherent proto-intelligence on a very subtle level. thnk you.
@@anastasiailieva7800 because it’s not a chemical reaction.
@@besotoxicomusic You mean that chemical reactions are due to inherent proto-intelligence? Interesting.
it's up to you to first prove that they do
👍
What I want to know is, what kind of bonds form my chakras?
that video was very funny 😁🤣🤣🤣🤣❤😹
❤️🙂
Uh, steps 3 and 4 of the criteria for mineral status are totally meaningless. Excluding energy or subatomic particles, anything we're in contact with is composed of elements or compounds and can be characterized by a chemical formula. That is akin to saying anything in chemistry is a chemical. Anyone in disagreement, please show me something on Earth (again, excluding energy or subatomic particles) that does not fit those two criteria.
No, not everything can be characterized by a chemical formula. We are talking about a repeating formula unit. Things that aren't crystalline don't have that.
They’re not rocks, they’re minerals
And of course, they can cure illnesses with good energy.
As a former pagan I have tons of rocks that I once thought to be majickal. They are still beautiful.
What are you now?
@@tyton3 atheist
@@robinhood20253 what are your thoughts on the person of Jesus Christ? I’m interested in the different opinions folks have.
@@tyton3 I am inclined to believe the story of Jesus was possibly based in the beginning on a preacher who was executed, although the details , even his name , are suspiciously similar to other myths within the pagan culture at the time. His date of birth, virgin mother the Sun or Son all can be found in several pagan pantheons.
@@robinhood20253 oh ok. Very interesting. I’ve heard about the similarities between Christianity and the religions of old-er. Mithras, Osiris, Zoroastrianism. I however can’t quite say I’m convinced of the validity of such claims. It is thought provoking, nonetheless. Thank you
Jesus Marie...
Hey Dave, love your hard work on getting the mass of morons to believe truths that man has proven hundreds or even thousands of years ago. It's shocking how many people are clueless in our modern world. I don't know if you know the guy on the channel " miniminuteman" but it seems like you both could be good friends. Check him out. I'm certain you will like this dude. He kind of reminds me of you .
Where can I buy these beautiful rocks ?
Doesn't he sound like someone from FNaF?. Or am I tripping
I am here....I found you from tik tok.... said you were giving away bismuth crystals....I am down...I want one from pink Floyd comfortably numb....can we????
The earth is flat
Aren't you a little lost, kiddo?

First comment!
You missed Ceyhun Girgin by an hour, sadly. Maybe next time.
First
that was elemental composition 😂

Your intro music makes me wanna chew obsidian
Yummy isn't it?
