What Are Volcanoes? Crash Course Geography #21
ฝัง
- เผยแพร่เมื่อ 25 ก.ค. 2021
- Today we’re going to take a closer look at these beautiful but dangerous landforms as we explore the different types of volcanoes and trace the patterns of volcanic activity around the world. From the explosive power of a stratovolcano like Mount St. Helens in Washington to the quiet but consistent eruptions of a shield volcano like Kīlauea in Hawaiʻi, volcanoes are like windows into the center of the Earth helping us understand more about how it all works.

#CrashCourse #Geography #Volcanoes
I always thought of volcanoes as angry, since they blow their top, but they look pretty happy in this video!
It's ok, no need to be hot headed about it
Speaking as a licensed geologist in the pacific NW, this is a great series but is WAY too short to do Crash Course Geology true justice.... we're not merely a subset of Geography. I'm biased, but it really does deserve it's own course. That said, what a great job CC has been doing summarizing geologic features and processes and super props to Ms. Carrere for excellent presentation!
It’s almost human geography time. This series has been amazing so far. I’ve been interested in geography for the longest time but haven’t known any good resources to learn it
same here person
Gotta say, the first couple of videos in this series the host spoke way to fast but now she's got a much nicer tempo 👍
Clear improvement
Simply = They are the pressure cooker valves of earth.
0:08 what a flex on Tom Scott 😂
She must not have eaten the Icelandic-Mexican fusion cuisine.
Just watched that video yesterday.
The squeaky toy noise XD
Wonderfully done! Thank you for such a great series thus far, just caught up with everything!
i'm amazed about the fact that tom scott also uploaded a video about volcanoes today
I love this
I also love volcanoes.
Bout time you guys do geology and volcanology videos! Finally! My area of passion
The Monteregian hills (which include Montreal) were formed when the North American plate slid across the New England hotspot ~125 Ma ago. Underground volcanoes made huge chambers of hard plutonic mafic rock. During the last glaciation period, glaciers scraped the ground, leaving nothing but the hard volcanic rock intact. Now we have a chain of hills from Montreal to the state of Maine that looks like the hawaiian island chain.
That milankovitch cycle stuff wild-and wildly controversial. Good for you guys for putting it in a video.
Tom Scott just posted a video of him trying to film Iceland's newest volcano. Worth a watch.
Hi Crash Course supporter here from the Philippines 🇵🇭🇵🇭🇵🇭😁👋👋👋
Welcome to the club! You never forget your 1st volcanic eruption, no matter how many more of them you witness (or so I am told by geologists, I've only seen 2, and they were both on the same volcano 12 days apart).
When the earth booms like that, it seems to grab you from the inside of your chest.
Another stellar episode!
Nice , i always loved geography
hi CrashCourse, hi everyone " very good episodes
I really like learning stuff ", :)
im getting more and more intrested into geography
That little animation of the volcano on the top right of the intro was so cute, and I couldn't help but laugh then I remembered what volcanoes do, and really wish someone had hit the little guy's snooze button before he was awoken 😂
When I come across anything related to Volcanoes, I get reminded of what lies beneath our feet; I think for a bit, scared and then forgets everything because of 'day to day life'.
Only to be reminded again.
Well, it's a great video.
nice I love volcanos thanks for that information girly ❤
Geographer looks a good job. You get to go to very exciting places.
The beginning of this kinda scared me when I thought back to those 18 people in New Zealand last year who were doing exactly the same… and now they aren’t here any more. 😢
That lil volcano is so happy!
Excellent content.
Awesome!
Thank you for the lesson 🌋
extensive coverage...nice video
Incredible
Thank you! 🌋 💥
THE VOLCANO IN THE THUMBNAIL IS ADORABLE
this video is so helpful! Watched it twice. The girl has explained it well too
This video could be unpacked into a one-hour course/documentary.
omg, amazing
wow
appreciated
I thought she was rapping terms at first before realising I was watching the video at 1.5 times of speed.
Tom Scott just uploaded a video about a volcano in Iceland lol
The start of this video reminded me of "the story" from friends
Is all the under water volcanoes around all the Islands specifically ? And if so if they go off hard what would happen to the Islands?
Volcanoes: Planet Earth's never-ending acne problem :(
Oh nice
Is there an estimation for how long Earth's geological activity will last?
Wow and on the same time that Iceland has been having an active volcano. What a coincidence, or maybe not?
I never imagined vulcanoes were so happy.
"the floor is lava" screamed at drunk geoscience students works world wide :'D
A topic for Crash Course Geology?
forbidden syrup
Volcanos are basically earth zits.
With earth blood and pus being magma/lava and mentle.
It's H2S that smells like rotten eggs and SO2 that smells like striking a match
Has CrashCourse done an episode on different geographic projections?
It's clear that the map overlays depicted @ 3:07 are using different projections. It's not as noticeable near the equator, but the volcanoes near the Arctic region are depicted farther north than they actually should be -- the volcanoes on the Kamchatkan peninsula and Aleutian Island chain are all offset, and the volcanoes in highly-active Iceland are depicted as being in Greenland, the latter of which is devoid of active volcanic activity.
Otherwise, great episode -- very informative!
No Volcanos in South Arica. Thank, Someone.
What part of the earth could be lost by them in time
Still waiting on crash course geology
*pew pew mountains*
👍👍👍👍👍
Unsqueezing?? Is that like unfreezing??
Ayy chemical weathering time
7:25 What's "Tahoma"? Did you mean to say "Tacoma"?
Tahoma and Tacoma are alternate forms of the name of the mountain.
In the native Salish language, it has an H not a C sound.
Tahoma is the original name for the mountain from language of the local Indian Tribes (or First Nations if you prefer) and was anglicized to Tacoma, (which should not be but is also a brand of truck...).
There are lots of Indigenous language names for Tahoma, including Tacoma and Talol, but the one most folks seem to advocate for the official name change is Tahoma. There’s lots of information on the internet about it, since renaming it picked up speed after Denali was officially renamed.
Good catch
You saved me from posting the same comment
(As an Aussie, even I spotted this mistake!)
It’s kind like Alexis rose in another time line lol
As a Geology major its kind of sad that the geology stuff is being lumped in with geography, they are certainly adjacent fields they are not the same. A Geologist is not a Geographer and vice a versa. It just feels disrespectful to try to relegate such a vast wonderful field as Geology to some subsection of geography (Another wide ranging field). As they say "Geology rocks, but geography is where its at."
Spock - he’s a Vulcan 🖖🏽 ( volcano )
A.S.O. Too much Volcano
have you seen how cute the geldingadalir volcano in Iceland is, and stop playing the floor is lava!
Sorry crash course I’m on summer break 😎
*Geology
Volcanoes are spice mountains.
Too much volcano..... no volcano
I have some bad news for anyone reading this comment: *THE FLOOR IS LAVA!*
Volcanos are the Zits of the Earth.
This is exactly why I question how much of an impact humans have on climate; Definitely have an effect but compared to what volcanoes can spew???
I wish we could put more into answering these questions
First like!
2:05 ew, "miles"...
Ah yes, Earth's pimples
Volcanos are the pimples of earth that the gods decide to pop in order to make pimple popping videos
I eat volcanos
first
Simple. Big Earth Pimples.
