This is why i love that youtube exists. I get to see this stuff id normally only find in some advanced lecture type stuff, and i can just watch it on a whim for the sake of my own curiosity. Thank you for making this video Mike.
Its honestly sad that the education provided by the government is of lesser quality then the education you can find from creators like you. Thank you for your work and thank you for making this free.
This is the best explanation for relative dating that I have ever seen. I do Science Olympiad (Div C, 9th grade) and I am doing Geological Mapping. Your channel has been a massive help for me. Tysm.
Thanks Mike. This is an exceptionally clear and well made video on relative geologic dating. Perhaps you can do a part 2 covering the different types of unconformities, more on the principle of correlation, the principle of faunal succession, and index fossils.
Thank you for all the educated earth science videos. I am currently studying for CSET and your videos really help a lot especially this relative dating of rock layers. I have seen similar rock layers showed up on written response and was so clueless as none of the study guides mentioned anything about how to date rock layers. Until I came across your video…. The illustration and the way you presented the materials make everything seems so easy to understand. I just can’t thank enough for your gifted talent in teaching and I enjoy watching every video you made.
You are a very good teacher!!! Your explanation of each layer of information, then repeating previous points and connecting them to the next layer of knowledge is so helpful. Thank you.
Loved the examples. Paused the video and went through them before listening to your explanation to see whether I'd understood the stratigraphic principles. Was quite fun!
This video was a lifesaver. ❤❤ My geology teacher literally didn't go over this, so I was freaking out 😂 I also totally forgot my earth science teacher had taught me this using the ESRT
i've never had geology lessons and in half hour i've learned to analyse so complex histories if only school had such stuff. imagine how smarter we all could be if we would replace repetitive timefilling lessons with such as this one
It wasn't meant for you lmao it was for that insulting guy up there who made some ugly remarks abt the pun. You see I forgot to address the name. well hu cares anyway
You Sr are an amazingg educator, thank you so much for these videos, I have been trying to learn more about geology, in order to better understand Cape Verde islands, where I am from, and your videos have given me hope to one day understand it better and if possible give a contribuition for the improvement of Life here.
Just a wonderful presentation. I knew nothing about geology before. And now every time I am passing through a 'cut' in the mountain, I will stop. In fact I may become a traffic hazard and please let me know your address so that I can send you all the tickets that I am going to accumulate given to me by the Highway Petrol. I really thank you for this wonderful explanation.
WOW! 🤩This is such an informative and understandable video! Is there a place where we can download some example problems like the ones you worked through at the end of this video?

I like how you explain all this and i have some New information about rock lairs. In the ash from mount St-Helen that have deposited less than 50 years ago clearely show signs of l'air formation... End a start of minéralisation whit out the pressure that we thought was needed to form them.
Do you have an updated version of the handout? The one linked seems like it might be an older version (number of rules is different). Thanks and the content is awesome!
If you need the 7 rules for science class: 1. Sedimentary rocks form as sediments are deposited on the bottom of a body of water. 2. Weathering and erosion of rock layers occurs on the surface (not under water). 3. The layers of rock on the bottom are the oldest. 4a. Sedimentary layers are deposited horizontally. Deformation includes folding, faulting, and tilting. 4b. Intrusions are younger than the rocks they metamorphose. 5. Faults are younger than the rocks they cut through. 6. Uplift, weathering, and erosion, and subsidence forms unconformities. 7. Inclusions must be older than the rock they are in.
Had to watch for class. Really helpful explanations. Out of curiosity was there meant to be two Rule #4's? Was it a two-part rule? Or just a typo? I just want to make sure I am understanding it correctly.
Thank you for clearly explaining the sequences. However, I have a question. You give us rule #4 as the Law of Original Horizontality, then you repeat rule #4 with Intrusions. Then rule #6 is about faults, and a repeat rule #6 as Uplift, weathering, and erosion. Then rule #7 as Inclusions. Did you mean to include the two items in rule #4 and rule #6? In the first rule #6, shouldn't you use "than" instead of "that?" No offense, I'm just detail oriented. None the less, I totally enjoyed the lesson!
In 12:45 I think it is safe to say the faulting came after the tilting , otherwise we would be having a fault having an hyperbolic surface , as well as the rock layers nearby it would also had being kinda folded to the direction of the motion in each side.
A global flood explains sedimentary layers much better. Type in folded mountains in Google images and see what the majority of the mountains look like. Try bending rock and see what happens. Could be that all the layers were soft when the mountains were formed. Makes more sense than fossils being formed at the bottom of oceans. I scuba dive and I don’t see any dead fish being buried. Most dead fish float. They usually get eaten and torn apart by scavengers either on the beach or sea bottom.

I have learned more in the first 2 min of this video than I have understood in 8 weeks of my online geology class. GREAT VIDEO!!
Thank you. The texts on the screen, animations and diagrams were all very helpful, and your explanations very easy to understand.

Missed almost this this entire topic in school and this really helped me understand it and make it seem less menacing. Thank you so much!
Thanks for making that so easy to understand! I'm not confused anymore; I'm ready for my Historical geology midterm! Luv & light blessings 💚
awesome! how'd you end up doing??
This video was extremely helpful, presented and explained wonderfully. Thank you Mike, hugely appreciated.
Thanks for the awesome vid, I must say this... I am a middle school student, and I UNDERSTAND ALL OF THIS!!! 😊 👍😮📚🎒
Thank for this! I have a quiz tomorrow and my teacher did not explain well.
Please continue making these videos. ❤️️❤️️
Thank you for your videos and for breaking everything down to make it easy to understand.
Thank you so much for making this lesson so interesting and easy to understand! More power to you!

Superhelpful vid. Exactly what I needed to inform myself. The internet at its best. Thanks
I guess this is the best TH-cam video so far on relative dating.
Great job man! Very organized and easy to follow. Keep up the good work!
there are two Rule # 4s haha but great video! The animations help a lot. Thank you
ya at first I was a little confused on this comment, then I finished the video. haha
Very informative and instructive video making easier to figure out the ordering of geological events and relative dating.
I was absent in school and miss this lesson but after watching this I understand everything thank you😁😁😁😊
Omg this kind of lectures are really amazing, and quality of teaching also good, we needed dam this in our school and Colleges ,Appreciate ✨👍🏻
awesome job, learned a lot more than my teacher
You make a difficult subject seems easy. I like your presentation: clear, logical and simple.
Glad you think so!
you explained it really well. thank you for the wonderful presentation.
This is the best video I've ever watched on this topic.

was my college instructor, I'd always get an A. Great tutorial!
It is a very clear and simple lecture !!!
EXCELLENT explanation and video. Thanks very much. Greetings from Mexico City

Thanks Mike....after reading the text, then watching the video, uncomformities and relative aging make more sense.
you basically taught this section to my students !!! thanks
7:27 Would that be considered rolling hills? Or would it turn into roling hills?

Excellent lecture and thanks for this amazing video

an example on 15:59 does this really not have any folding? if there isnt, shouldnt it be that the lines are horizontally "perfect"?
awesome dude...thanks for the detailed video
Can't thank you enough for this video !

This is very useful

thank you very much, you explain everything so easy
Great explanation! Thank you a lot!
I understood this more than my college text book. Thanks!
This was SOLID
Nice teaching..i loved it. i have a doubt at 19:09. why wont the deposition of siltstone occur after faulting?
8:45 Does that mean that whenever sedimentary rocks are exposed (not underwater anymore) that that's considered an uplift?
yes
It could be a lowering of sea level like during an ice age
very helpful . Thank you
Amazing video
Thank you so much for this lesson!!! I really appreciate it!
Which software you used to create a fantastic video like this?
very helpful bro thanks
Very informative, thank you!

You saved me, Thanks alot!
Awesome video!
very helpful video!! I am ready for my midterm exam lol
michael, you're a blessing
You are fantastic! Thanks
Very helpful👍 thanks a lot
How did you infer that there was another period of uplift at 22:23 ?
at 16:42, can the sequence of events be: A, B, D, Uplift, Weathering and Erosion, C?
Very Informative and Descriptive
Would you you consider a global flood as a better explanation of the evidence versus uniformitarianism?
