Hello everybody, it's been a long time since I have posted on this channel. I am now professionally trained and ready to take Study Buddy Studios to the next level... to The Digiverse! I can create highly interactive virtual classrooms for various subjects that play like video games and can connect teachers with students through video confrence calls within the virtual classroom. I am looking for a Canadian university or college to sponsor me to make this happen and I need your help. Please watch my newest upload to this channel, share and leave a comment. Cheers. th-cam.com/video/P4soBPuFmBo/w-d-xo.html
Thanks Jim. You should see what I am up to now. Check out my newest upload to see. It is still processing so you might be the first person to see it. Cheers.
Being an graphite moderated reactor I'd say graphite can cause problems sometimes hurt or kill the reactor me being one of them I flat out hate graphite I throw every insult in the dictionary at graphite
I found this via yours! As soon as the 'rona allows places to reopen, I'll be heading to the local museum, to get an idea of what we have here in Northern Ireland.
Thanks for sharing this. I've marked it to come back in late spring and use it to identify the rocks & minerals in my brook. I appreciated your direct approach with information and camera sets.
Not a student, but I found this very helpful! Looking at buying some land in the North Georgia mountains and found some neat minerals and rocks, as well as a LOT of quartz. This helped me with figuring out what some of the rocks I brought home from the land site are!
As a native North Georgian (aka Appalachian American) I hope you have found life good here. A word of caution, if I may. Keeping Pet Rocks has been a popular idea for a number of years. These are truly wild and not meant to be kept as pets. One minute docile and aggressive the next. They can be very protective of humans they are familiar with. I, too, once thought this was a good idea until my Pet Rock, Krystal, attacked my neighbor right between the eyes during an emotional discussion about property lines. Krystal had to be released into a wilderness area. Welcome to North Georgia.
Great video! All discussion aside as to how you got the rocks to spin 🙄😂, it's really cool that you did that. So much more helpful being able to see the rocks & minerals from different angles rather than looking at a flat picture in a book. Awesome job!
The table sits atop a "lazy susan". A common feature in display racks for retail merchandise. A "must have" for the instructional presentations. Thanks for noticing.
Honestly thanks this was one of the best videos that I have watched in a long time. I have been collecting rocks and minerals for a long time.. finally I know what I have. Thanks for a great video :)
I always remember that the difference between limestone and dolostone from a geographers perspective is that the dolostone is like a sponge to water, limestone has a tight interlocking crystal structure and water penetrates along joints and bedding planes. The marble is metamorphosed limestone or dolostone - interesting video, thanks
Thanks for sharing this informative video on rock and mineral identification! I found it really helpful to learn about the different characteristics to look for, such as color, texture, and hardness. I also appreciated the tips on using tools like a magnifying glass or scratch test to further narrow down the possibilities. As someone who is just getting started with rock collecting, this video gave me a great foundation for identifying specimens in the field. Keep up the great work!"
Very informative video on minerals identification. I am an amateur rock hunter this helped me immensely. If you have videos on rock identification, please upload them
I studied off of this video and got a better understanding for my lab test. The only thing I would say is if you could label whether they're igneous, sedimentary, metamorphic. I knew some but not all. No worries, I looked it up. But other than that, this was amazing. Thanks so much.
Good evening sir, i found a rock behind our house, i want to know what type of rock is it, im from sierra leone west africa, send me your watsapp number to communicate better please thank you
I'm at Big Bear Lake CA and I'm finding large chunks of pink, white and grey "quartzy" type rocks. They are fantastic! I studied geology a bit 35 years ago and I've forgotten so much. I think these are granite... Maybe a few marble?? Thank you! Great video!
Im learning this for the sheer chance I'm thrown through time and have to rebuild the world. Not having to figure out what raw materials are and smelting them.
So...I never knew being a geologist or studying rocks was so damn cool. I kinda wanna do it...I've always loved rocks lol but genuinely, I could spend hours rock hunting
Nice concept. Had trouble seeing colors and textures.would like to see more with more info, maybe uses or where they are most often found. Nice job over all
@@SSFCstudybuddy hi buddy i've got a quick query that's been bothering me..may sound stupid mind! anyway with the scratch test is there a certain way to do it, for example quartz having a higher hardness than calcite, if i had a nice flat face on a piece of quartz (amethyst for example) and a piece of calcite with a very sharp point or edge and tried my very hardest to scrach the face of the Amethyst should it be impossible for it to leave a permanent mark or will it scratch it just simply due to the amount of force used? in other words should i just be testing it by gently scratching it instead of with force (i know a knife is lower on the scale than quartz but i just feel like if i really tried to mark that quartz with a steel blade i could even though in theory it shouldn't be able to...thanks buddy and great video! 👍🏻💎
this is helpful for rock hounds as well. i live in the Adirondacks and have seem most of those in my travels, a few i know on sight but a few can be tricky. thanks for posting!
It would be nice if you told us something about how these originate. Like where was this Orthoclase found, how widespread is it, where is it typically, and how is it formed?
My father had alot of this rocks and unfortunately we couldn't identify we were in very small town, now he passed away may Allah gave mercy on him, I want to take the good job from there, thank you so much.
Although I'm still in high school but I find it very interesting. I would advice majority of the public to be geologist because it is very important in life. As for me I would love to be a mineral geologist
I admire your passion and the ability to know what you want to learn. It is a bit too late for me (too late in life), so I do encourage anyone who is slightly interested in rocks and minerals to give it a go. I am trying to teach myself now....I love rocks!!
Oh I wish I could rent you for a day to identify my rock hoard. Lol. Its difficult to figure this out from online resources. Thanks for the info sir! 👍🏻
2nd time watching. Actually learned some information this time, after uncovering the processes of recognizing some gem markings in the rough. Diamonds and Gold beware when I get off this leash!!!
thank you so much the video was helpful but, the minerals and rocks we do in class are sooooo different from the ones in the video. the color and structure always changes i want to be able to identify a arock or mineral just by looking @ it... is that even possible?
This specimens are in general, some similar specimens have different appearance. For example : pyroxene, sometimes ocured in crystal form. And some others ..
You said that quartz has concoidial fracture. I thought that was the smooth curves seen in flint and obsidian in the angle and appearance of a hole in glass made by a BB. Not trying to sound smarty, I'd really like to know. Thanks for the excellent video.
If a young person has both a high level of academic ability, along with a desire to work in a physically demanding job with some real cool people, then geology may be for you. The need for field analysis never ends. You need discipline, courage, and a vast knowledge of physics, chemistry, biology, mathematics, mining technology, safety training, and a huge amount of common sense. Geology, is not for the faint of heart, you'll never last. Better stick to the lab. We should all get down on our knees and thank geologists, for their hard work, because most of what we touch every day wouldn't exist without their work.
Good day. happy 4th of july may you have many more. hahahaha, Thank you for posting thins video. How did you determine the hardness and gravity of those rocks? what is poricpioritodic?
Hi, I am rock enthusiast and it has been my passion so I can tell you that for hardness we use the Moh's Hardness Test. The first thing you do find a place in the rock that scratching will not matter. Then the first thing you do is to use your fingernail and see if you can scratch the rock and if you can see a line then your rock is a soft rock. Moh lists as an example that talc can easily be scratch. If no mark then you are going to see if a coin can leave a scratch mark. If it does then you have a list of rocks it could be. Next to scratch with is a small knife blade, a piece of glass, and from there a piece of glass. You also can use the rocks that Mohs has on its scale. So if you can can't scratch it with a pocket knife but can with a piece of quartz rock, then looking at Moh's scale you may have apatire?? It isn't rocket science correct but it is a good indicator. I really like the streak test. But I would suggest buying a good rock and mineral book for identification. My favorite is the Audubon rock and mineral guide. It is incredible!! I also love my Eyewiness Handbooks Rocks and Minerals guide book by Chris Pellant and joining a local rock and gem club is really great too!
Wonderful! I can't wait to get into this one but will have to learn some vernacular relating to rocks and minerals first, like "cleavage" and "conchoidal fracture".

You are a unique Geologist, the teaching method is exceptional. I learn a lot here. Thanks very much
Yes!
THANK YOU, ONE OF THE BEST DISCRIPTIONS & CLEAR PICTURES I'VE SEEN.
Hello Mrs. Robert here I love your channel. I have been slacking on for 33 years and have no plans to stop
This is so informative! I recently started hunting agates and it's great knowing what else I find along the way!
I found this via yours! As soon as the 'rona allows places to reopen, I'll be heading to the local museum, to get an idea of what we have here in Northern Ireland.

This is helping with my Science Olympiad competition. THANK YOU!
I like video
Sure wish I'd had this channel to study, at night, when I was in school--thank you! A super review of some of my fave minerals!
Honestly thanks this was one of the best videos that I have watched in a long time. I have been collecting rocks and minerals for a long time.. finally I know what I have. Thanks for a great video :)
💎Wish you had been my teacher at school in 1970, a very good and easily understood video, well done!💎💍
Очень интересный фильм, познавательный.Смотрю и оторваться не могу! Спасибо автору за удовольствие рассматривать эти прекрасные образцы.
I've always been interested in rocks and their various colors but don't know how precious they are until I see this clip.
Loved this wonderful video! Youve answered so many questions. You have a great narrative voice!
Yes !! I've been leaning about all of the rocks and min,I think this was a very good 😊 video to watch and learn,thank you for sharing,Linda ,
Nice work. Reminds me of my university days going on Geology field trips. Loved every minute of it.
This video made me laugh, it made me cry, its the feel good hit of the year!
How's 2020 treating you? :-)

thnx a lot..
Great job of compling this, excellent for learning about base geology, thank you!
This video taken form my practical exams is very good thanks to making this video
Thank you, very awesome and helpful. So excited to finally recognize stones.
Im viry good

Now you need a video on how they are made and where they are mainly found. Thank you!
Да согласен с вами !
0:00-8:49 minerals
8:49-19:16 rocks
Wondering where you are from(?) I find it funny when there’s an option of how to pronounce, you say it differently than I do. I love this video!
It's a wonderful video, but I would also categorize them into igneous, sedimentary and metamorphic.
Regards!
Oh I wish I could rent you for a day to identify my rock hoard. Lol. Its difficult to figure this out from online resources. Thanks for the info sir! 👍🏻
I love quartz it looks beautiful and its so easy to find :DD
2nd time watching. Actually learned some information this time, after uncovering the processes of recognizing some gem markings in the rough. Diamonds and Gold beware when I get off this leash!!!

This specimens are in general, some similar specimens have different appearance. For example : pyroxene, sometimes ocured in crystal form. And some others ..
Thank you for share about the stone rock.
Правда очень интересно.
You said that quartz has concoidial fracture. I thought that was the smooth curves seen in flint and obsidian in the angle and appearance of a hole in glass made by a BB. Not trying to sound smarty, I'd really like to know. Thanks for the excellent video.
Yes,
This quick vine was as good as any Geology class I've ever had in college, or better, thanks, sir!
