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 ok, no need to be hot headed about it

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

The squeaky toy noise XD Wonderfully done! Thank you for such a great series thus far, just caught up with everything!

@simjans7633 2 года назад

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.

@sussekind9717 2 года назад

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.

@drewliedtke2377 2 года назад

That milankovitch cycle stuff wild-and wildly controversial. Good for you guys for putting it in a video.

@AlphaGeekgirl 2 года назад

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. 😢

@LtNduati 2 года назад

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 😂

@aniketshrivastava4908 2 года назад

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.

Geographer looks a good job. You get to go to very exciting places.

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?

@gibranhenriquedesouza2843 2 года назад

Is there an estimation for how long Earth's geological activity will last?

@Club-kc9wl 2 года назад

Wow and on the same time that Iceland has been having an active volcano. What a coincidence, or maybe not?

Volcanos are basically earth zits. With earth blood and pus being magma/lava and mentle.

7:25 What's "Tahoma"? Did you mean to say "Tacoma"?

@varana 2 года назад

Tahoma and Tacoma are alternate forms of the name of the mountain.

@drewliedtke2377 2 года назад

In the native Salish language, it has an H not a C sound.

@bgclo 2 года назад

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...).

@khills 2 года назад

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.

@yaardvark3451 2 года назад

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!

@Gadgetmaster101 2 года назад

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."

@TheRogueRockhound 2 года назад

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
