00:00

I dare you to find somebody who hasn’t, at some point in their life,

00:04

uttered the words, “Oooh, cool rock!”

00:06

Those three little words connect you to powerful forces that shape the world,

00:10

people who lived thousands of years ago,

00:12

and the squirmy little kid inside you who never grew up.

00:15

Because let’s face it: rocks are cool.

00:17

We’ve transported them across long distances as far back as prehistoric times.

00:22

We’ve admired them, traded them, built pyramids and skyscrapers out of them.

00:27

And to this day, even a tiny pebble is part of a bigger story that began long before us—

00:32

and will continue on long after we’re gone.

00:35

Hi! I’m Sage, and this is Crash Course Geology.

00:38

I’m an artist and creator who’s obsessed with earth science.

00:42

You might know me from my YouTube channel, Sage the Bad Naturalist,

00:45

where I make videos about fascinating fungi, and scary sludge,

00:49

and various experiments that… never go exactly to plan.

00:53

And I love a cool rock.

00:55

But geology is so much more than that.

00:57

In 25 episodes, we’ll dig deep into the forces that shape our planet from the inside out.

01:02

We’ll dial back the clock to Earth’s fiery youth, journey to its center,

01:06

and uncover the churning, dynamic forces that sculpt its surface,

01:10

making it possible for you and me to exist at all.

01:12

We’ll discover how fossils and layers of rock

01:15

clue us into what happened before humans showed up fashionably late to the party.

01:20

And Dwayne the Pet Rock will catch us up on all the lore we missed.

01:24

Huh? What’s that? Girl, Earth did what now?

01:27

But geology isn’t just about the deep past.

01:30

It’s also about the present and the future!

01:32

It’s about the gems that decorate our fingers and the minerals that power electric cars.

01:37

It’s about clean water, healthy soil,

01:39

and preparing for hazards like earthquakes and volcanic eruptions.

01:42

It’s about tapping Earth’s geothermal energy and finding rocks to store excess carbon.

01:47

Geology puts our lives in a whole new perspective.

01:50

‘Cause it’s not just microscopic minerals and enormous mountains.

01:53

It’s asteroids and deep-sea trenches and worlds beyond our own.

01:58

One tiny, ordinary pebble can teach us about our current moment

02:02

and the enormous timescales that stretch beyond us.

02:06

So meet me back here to check out some cool rocks—and much more—together.

02:11
