How tall can a tree grow? - Valentin Hammoudi

What makes a tree grow tall? And do trees ever stop growing? Explore how photosynthesis and gravity can affect and limit the height of trees.

--

Reaching heights of over 100 meters, Californian sequoias tower over Earth’s other 60,000 tree species. But even these behemoths seem to have their limits: no sequoia on record has been able to grow taller than 130 meters. So what exactly is stopping these trees from growing taller, forever? Valentin Hammoudi investigates why trees have limited heights.

I would love to see this artist again!

I think trees are having a secret competition on who can grow the tallest

[mrmagus]

I've been wondering this for a while.

Finally I'm able to get to the root of the question ;)

"I only date trees taller than 60 meters"

[AokiCyber]

lmao i legit laughed when the bird sounds like its going to explode

[k.a.s]

The educational value of these videos never fail to amaze me. I wish they showed me more of this type of videos in high school science classes.

[stressednspicy]

never knew trees could be cute until i saw this animation

I'm always impressed by Ted-Ed videos, but every now and then there is one that is such an incredibly informative piece of art that I cannot believe it exists. This is one of them.

Tree: I’m gonna keep growi...

Gravity: I’m boutta end his whole career

The audio in this video is superb, blends perfectly with the minimalistic but cute aesthetic and the soothing narration.

[jeemonjose]

The sound mix of this video is so good

[chasekautz]

They’re mixing up Sequoias (Sequoiadendron giganteum) which grow in the Sierra Nevada, and Giant Redwoods (Sequoia sempervirens), which grow on the north coast of California. Giant redwoods are the tallest trees in the world, but don’t grow in the Sierra Nevada.

How did you make the trees so cute😂😂😍😍
Edit: Thanks so much this is the most likes I have gotten💝💝💝💝 (current: 541)

I especially loved the harmonica-bird!

[AntonioKowatsch]

I love these Ted-Ed videos. They are even better than the actual Ted Talks because they're condensed knowledge. Just my type of information.
I don't like people telling stories. I like facts.

[groenpaardje]

Really top notch animation and sound design! The artists did a really great job with making creative visualizations of the narration.

[lemondrop]

i love the calmness of this vid but the bird-harmonica sound made me jump lmfao

[pathtobillions]

So can trees grow taller on Mars or other planets with lower gravity? Would be interesting to see how tall they could get.

[mrkhunt.]

Brilliant video as always, by the way, how do you make the animations?

Happy Pi Day!!
