What Are Volcanoes? Crash Course Geography #21

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.

I always thought of volcanoes as angry, since they blow their top, but they look pretty happy in this video!

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

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!

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.

Tom Scott just posted a video of him trying to film Iceland's newest volcano. Worth a watch.

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.

hi CrashCourse, hi everyone " very good episodes
I really like learning stuff ", :)

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.

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 😂

[AlphaGeekgirl]

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. 😢

[ACivillage]

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.

[Iisa]

"the floor is lava" screamed at drunk geoscience students works world wide :'D

[dreamoftheendless]

THE VOLCANO IN THE THUMBNAIL IS ADORABLE
