What's changing in Earth's core? - Shannon Odell

from TED-Ed · host TED-Ed

Explore the science of why Earth’s atmosphere is losing hydrogen, and find out what other leaks could affect life on our planet.--A hydrogen atom is traveling high within the outermost layer of Earth’s atmosphere. This particular atom first entered the exosphere millions of years ago, but today it overcomes Earth’s gravitational pull and escapes, joining the roughly 90 tons of material that leak out of our atmosphere each day. Should we be worried about these leaks? Shannon Odell digs into our planet’s imperfect plumbing.Lesson by Shannon Odell, directed by Eva Münnich, Strange Beast.This video made possible in collaboration with Speed & ScaleLearn more about how TED-Ed partnerships work: https://bit.ly/TEDEdPartnersA special thanks to Mary Kang and Jean-Baptiste Koehl who provided information and insights for the development of this video.Support Our Non-Profit Mission----------------------------------------------Support us on Patreon: http://bit.ly/TEDEdPatreonCheck out our merch: http://bit.ly/TEDEDShop----------------------------------------------Connect With Us----------------------------------------------Sign up for our newsletter: http://bit.ly/TEDEdNewsletterFollow us on Facebook: http://bit.ly/TEDEdFacebookFind us on Twitter: http://bit.ly/TEDEdTwitterPeep us on Instagram: http://bit.ly/TEDEdInstagram----------------------------------------------Keep Learning----------------------------------------------View full lesson: https://ed.ted.com/lessons/what-s-happening-to-earth-s-core-shannon-odellDig deeper with additional resources: https://ed.ted.com/lessons/what-s-happening-to-earth-s-core-shannon-odell#digdeeperAnimator's website: https://www.studiocool.coolMusic: https://www.campstudio.co----------------------------------------------Thank you so much to our patrons for your support!
