Such a pleasure to see this video and read all of these comments. I'm enchanted by all the talk of changing majors to Geology. Me? I'm 63 years old and living my second life. Back in college again and wishing I had discovered geology when I was 18! But for now, I'll thoroughly enjoy Geology 101 and Stephan's videos!!
That's cool! Are you doing geology now?
I had a rock as a friend one time.
Your comment alone is ok but your name takes it up a tier

Hello, I'm in terminé Scientifique un France and your video helped me to understand the beginning of geology... Your explanation were very precise and it was easy to hear your sentences... Good job
I'm just starting to learn about Geology, thanks for a great video!
omg same i love rocks, volcanos,earthquakes,fossils anything about it
was debating whether to take bio or geo. Gonna take geo!!!!
woohoo glad to hear it!
A suggestion: With the study of Earth Science, you could also cover not only just the study of the earth itself, but also weather, oceanography, botany and zoology, and other earth like objects in space, and etc (with geology comes geography naturally). So essentially, in the end, you become a Bio-Geologist/Astronomer.
MemoryLapseDM hi! so I’m trying to figure out if I really want to be a geologist, but seeing it’s mostly based on rocks, it doesn’t feel as appealing, however, wha you mentioned is! I want more about nature and the ocean and natural disasters so, since I saw your comment, what would you recommended me to study? please help me
Ceez Geez this is why I’m here too lol
Maybe check out geoecology, geosciene and physical geography.
Thanks Stephan to share your experience and knowledge! Please make it a continuous video!
I am thinking of studying Geology at College... It is just so damn interesting, a rock contains stories about the past, only to be deciphered if you know how to look. I'm stoked!!
Great video!
I've learnt a lot! This really helps my future goal!
I am switching my major from Wildlife Bio to Geology, super excited
Thank you for creating this video! My children have really begun learning about geology in a way that they can understand. WE APPRECIATE YOU!
I’ve got admission in Geology 😍 Thanks to God ❤️
Thanks to science
Amen!
how can god beat science?
Ari Mae The one who made science! He can also destroy it ♥️
@@mangaart749 Yep! He is before all things and in Him all things hold together. He is faithful to Himself, so we benefit from it. lol, imagine if one day science left. Everything would go into chaos and die instantly xD
I defenetly love this science
Excellent lecture Pc Geo Kimberlite
Thanks for making this video. Really enjoy it
this is fantastic thank you

why it is larger crystals if it takes time to cool ?
If a piece of rock "flash" cools, meaning it cools down to Earth's surface conditions very quickly then the atoms don't have enough time to get together and form any crystal structure or they only form very small crystal structures. If a rock cools very slowly then the atoms have more time to make stronger and longer bonds between themselves and solidify into a repeating bond pattern, which makes it a larger crystal. This is mostly dictated by thermodynamics.
Stephan Hlohowskyj appreciated, can you tell me best technique to learn all words of Geology ? or where can I find all words of geology as I know that knowledge is more of scientific words.
forgive me

Please make more geology videos it helps a lot!!!!!😊😊
This is cool thanks for posting
The reason I'm here is because I'm fascinated with land and its connection to war/ battle. Ever since I knew what a sword was I've been interested in where/how we used land as a weapon. Oftentimes when I traveled or I a stump or a field I could imagine or see a battle taking play.
Geography just might be boring to me but I love looking at land and how it changes because of us. War
Very interesting
Awesome. Thank you!
awesome video! Very entertaining
Kudos
Nice video
Currency watching this on September 11th 2020 at 2:46pm as I'm supposed to be in a college zoom meeting to talk about my geology lab but my Professor doesn't seem to like me very much and isn't responding to my emails, didn't give us a reason he wouldn't start our meeting, didn't answer my questions about these online meetings start in our last meeting and there isn't anything in my syllabus about what we're supposed to be doing. So I'm watching this in hopes of gaining some information.
your video has really help me to learn more about geology
Thanks it's a good start for me
Thank u for this video
Nice video
Excelent video, i study geology in México, your vídeo is amaizing!
What to study to became a geologist I love social studies I wish I could take geography to became geologist pls make a video on what should we study to become geologist
thank you for making this. very informative
Nice video, thanks.
Hey! - loved ur video. is there any particular book(s) that u recommend for someone who has always been interested on this topic but never actually got into it until now (when i have a full time job, a baby --- and life.. haha) but i would really love to learn more about this on my free time! great videos!
Awesome content thank you
I want to understand the events from the grand staircase escalante, canyonlands, ( black dragon canyons in 70 rd)...etc
Lesson ONE for geologists should be the explanation of the catastrophism theory. This theory is based on the findings of the French naturalist and paleontologist Georges Cuvier around the year 1800. During the excavations when making roads through France, he discovered the fossils from land and sea creatures in the same layer, strata. But also in the layer on top of that and the one below. So he concluded that the planet Earth is suffering from a recurring natural disaster where flooding must cover a large part of the land even on high places. But I assume that this theory is neglected because nobody could think of the possible cause of regular floods. Ancient books tell us that our planet Earth is suffering from a cycle of seven natural disasters. The only possible cause of such a cycle can be a celestial body that orbits our sun in an eccentric orbit. Than that body, planet, will be close to the sun for a short while and disappear in the universe for a long time. That celestial body is also mentioned and even depicted in many ways. The Aztec Sun stone is a warning for this event. We explain much more about planet 9, the recurring flood cycle and its timeline, the rebirth of civilizations and ancient advanced technology in the e-book: "Planet 9 = Nibiru". It shows abundant and convincing evidence both in text and many depictions. It can be read on any computer, tablet or smartphone. Search: planet 9 roest
Great video 👌
I’ve got a geology test tomorrow
Same but a year after yours
thank you so mucch..you are helping me in my college studies..
i pronounce Earth, E-arth. any way, do you have another channel where you narrate? very nice flow WITH INFO TOO. rare
I came to learn about crystals, stayed for the Learning
Nice one,please I want to learn about Rock structures.
Nice video useful for even layman.
what an exercise
Said he streaming a terrible 720p ! Come On Man They manage to put accusable 4k to 8k but you let it down at the simple end Hmmm
I have a question about basalt and granite.
I get that basalt forms when the lava cools quickly and granite forms when it cools slowly and that this difference contributes to some of the differences in those two kinds of rocks.
I also know from other research that basalt has a low silica content while granite has a high silica content and that this is partly why basalt is denser than granite and is the main kind of rock in oceanic crust while granite is more common in continental plate material.
My question is what factors determine the chemical composition of the lava as it's extruded?
Thanks.
The determining factor of the composition of a rock type is based on what the source of the magma is, i.e., where it came from. Basalt has a low Si content since it is usually mafic and is related to or comes from the Earth's mantle. Granite on the other hand is usually related to melting of continental crust or in very old granites to the formation of continental crust itself. These rules are not always perfectly correct but for the most part this is what determines the chemical composition of rocks on the surface.
Cool vid man!
hello sir .i have dout ..in which country have best for geology ?
pleasesir give Your opnions ...
Hi Stephan! I saw these 2 videos of yours and I liked them a lot (An Introduction to Sedimentary Rocks
and An introduction to Geology). Could you recommend me a book and where can I get it so that I can study the following: I would like to be able to recognize which rocks were formed by Glaciers, mountains streams, alluvial fans, foodplains, deltas, lakes and playas, desserts, dunes, estuaries, tidal flats, beaches, submarine canyone/fans, rivers and open ocean. I appreaciate a lot your suppport.
Magmaaaaa
Can someone tell me what I have, translucent pink material, spear head shape with (what appears to be)teeth marks and has a whole ,tiny fossilized fish inside of it when you hold it to the light. I have never found anything like this.
Thank you
pls mention another way for formation of igneous rocks other than from volcano
Igneous rocks can form from cooling of magma deep in the earths crust. This magma can then be brought to the surface by plate tectonics and faulting. This is more or less how the Sierra Nevada mountains formed in California
great video .I have question why is granite found far apart from it point of origin or are they other ways granite can be formed apart from volcanic eruption?
In the video I didn't go into enough detail about granite formation, but granite is usually formed deeper in the Earth's crust where it has time (e.g. millions of years) to slowly cool and crystallize. The Sierra Nevada Mountains in North America for example are mostly formed from granite that are roughly 60 million years old, they were slowly exhumed by geologic processes (tectonics & weathering) and now are at the surface. So granite can and often does form deeper in the Earth's crust where is significant heat and pressure, then it is slowly brought to the surface over long time periods.
am David Moffat studying geology at University of Nairobi, Kenya. I really like geology.
The longer the Ignious Rock takes to COOL the HARDER they are??
How come everything from volcanoes is Basalt black rock I have never been to a vocanic site (new) spuing up granit? I understand how pressure can change rock(metamorphic) but volcanic magma seems to only have Basalt. Which active volcano prduces Granite?
Not every volcano produces basalt but a lot do. In general the composition of a volcano depends on location (continent versus oceanic crust) and the composition of the magma feeding it. Basalt has more iron and magnesium while granite has more silica and aluminum. There are many different types of volcanoes such as Hawaii and Mount St Hellens
thnx bro even tho this is so old, it helped me in my science!
I wonder where he went?
Are you able to identify the minerals contained in this rock I found at the bottom of the Grand Canyon?
I probably could if I could see a hand sample, however I don't live in Arizona anymore. You can take a rock you want identified to a geology department of a nearby university. Most geo departments will help you identify the mineralogy, just call or e-mail them ahead of time. Usually professors or researchers are really happy to help the public learn about geology!
I thought I had replied, but I guess not. I'll post a link to the Facebook video, if you are able to view it there. Let me know if you are able to view it. I haven't posted on UA-cam yet. I turned the rock very slowly to all sides in the video, as each side is different, one strikingly so. When I found this, that night the Ranger gave a talk about the GC geology, but you really can cover much in an hour. I know some about the layers and how they were formed. This rock seems out of place of any specific layer and I wonder how it came to it's present shape. So many minerals in it. Here is the link, let me know if any minerals are identifiable if you would. I'll probably delete it on here in a week or so as FB has too much info on me. I enjoyed your post here, btw. Good introduction to geology. I watch Science & Discovery channels a lot and find it very interesting.
hi sir i didnt understand difference between garnite and basalt are they type of igenious rock and rock cycle is continue during vocalnic eruption if yes so how does sedimentary and metaphorphism formed thanx
Granite and basalt are both igneous rocks, however basalt forms usually from volcanic eruptions that reach the earth's surface and cool relatively rapidly. Granite on the other hand does not form directly from volcanoes but rather is magma that gets trapped in the crust of the earth and has a long time (millions of years) to form and crystallize. Then through plate tectonics and seismic activity the cooled rock can be exhumed naturally and seen at the surface, sometimes forming mountains. Additionally basalt and granite are chemically different, with basalt having more iron and magnesium, and granite more silica and aluminum.
i live in the uk and in september im going to start geology at plymouth. for my a levels i done geography and ph9tography and theology. i got a B in physics and two Cs in bio and chem at gcse. i was just windering how difficult is a degree in geology. i love it but idk if im good enough?...
Like any science degree there is a learning curve with the fundamental ideas, terminology, and concepts. Geology is different from something like physics because you need to physically see the rocks to really understand how the earth's system works. Geology generally requires more skill in chemistry, as well as basic math (algebra) skills. It really depends on how motivated you are to learn, anything can be easy if you are excited to continue to learn and understand more. Staying motivated is the key in any science, good luck!
Stephan Hlohowskyj hey thanks for your comment. Yeah i guess your right, im really motivated to learn i think as its a new stage and new skills i need im in a bit of a panic. But i am motivated so hopefully i'll be alright. Thanks!! :)
Is that green screen?5:27
You started good with this " Geology " video....Why did you give it up..... ?
Is there anyway I can email you with a question? I have a picture of a rock which i cant post here i would like some info on it
Hey I am 8 years old and I want to become a geologist how do I become one
do i have to be good in math to take biology?
hello sir I also want to become geologist and i am in 12th so can you guide the next steps to become a good geologist
Definitely need to attend collage/university for Geology. Since geology is an interdisciplinary science you will need to have a good background in math, physics, and chemistry so don't skimp on those classes, try to take calculus based physics and at least calc 2 in math. In chem you will need at least chem 2 and probably will benefit a lot from p chem. The rest of the classes should be in the geology dept wherever you attend. Good Luck!
So what did you take now? Please reply.
Geology like it
Where do I find the next part?
Hawaii's food must be rich in magnesium compared to ours.
How are you geologists ?
I want to be a planetary geologist it is my dream to become one.
Exactly I want to be geologist
Magma is Molton rock BELOW the serface LAVA is that molton rock ABOVE the serface
Was about to comment that too. Not a great way to start off a geology video lol
I want to be a geolagist
I need this on arabic .... Thank you
Where are all the flat earthers???
What is geology like in college?
It's a combination of many fundamental sciences, so in college you will need to take chemistry, physics, and math in addition to geology courses so you can draw on knowledge of these other sciences and apply them to the Earth and its processes. It's lots of fun but is hard work
Ogga booga me like rock
I'm completed MSc geology but there is no jobs in india ,only recommendation people got jobs, Govt sector have only limited jobs ,don't waste your time from ur valuable life.
