How eclipses proved that the Earth is slowing down MinuteEarth 2023-09-22 | This Product is supported by the NASA Heliophysics Education Activation Team (NASA HEAT), part of NASA’s Science Activation portfolio. The material contained in this document is based upon work supported by a National Aeronautics And Space Administration (NASA) grant or cooperative agreement. Any questions, findings, conclusions or recommendations expressed in this materials are those of the author and do not necessarily reflect the views of NASA.Without eclipses, our world would be a lot different because eclipses give us the ability to do science we otherwise wouldn’t be able to.LEARN MORE**************To learn more about this topic, start your googling with these keywords: - Corona: the outermost part of the Sun's atmosphere.- General Relativity: a theory of gravitation developed by Albert Einstein that says that the observed gravitational effect between masses results from their warping of spacetime.- Lunar Eclipse: an eclipse in which the moon appears darkened as it passes into the earth's shadow.- Solar Eclipse : an eclipse in which the sun is obscured by the moon.- Tidal Friction: strain produced in a celestial body (such as the Earth or Moon) that undergoes cyclic variations in gravitational attraction as it orbits, or is orbited by, a second body.CREDITS*********Cameron Duke | Script Writer, Narrator and DirectorSarah Berman | Illustration, Video Editing and Animation Nathaniel Schroeder | MusicMinuteEarth is produced by Neptune Studios LLC neptunestudios.info OTHER CREDITS*****************Photo of 1919 Total Solar EclipseCredit: ESO/Landessternwarte Heidelberg-Königstuhl/F.

A similar but distinct phenomenon often confused for a rip current.- Sandbar: a deposit of sand forming a shallow area in the sea or a river.- Surf zone: the area of the ocean where waves break near the shoreline.- Undertow: a current of water below the surface and moving in a different direction from any surface current. Also distinct from a rip current.- Wave Set Up: elevation of the mean water level at the shoreline due to wave breaking in the surf zone.SUPPORT MINUTEEARTH**************************If you like what we do, you can help us!:- Become our patron: patreon.com/MinuteEarth- Our merch: http://dftba.com/minuteearth - Our book: minuteearth.com/books - Share this video with your friends and family- Leave us a comment (we read them!)CREDITS*********Cameron Duke | Script Writer, Narrator and DirectorLizah van der Aart | Storyboard Artist Sarah Berman | Illustration, Video Editing and Animation Nathaniel Schroeder | MusicMinuteEarth is produced by Neptune Studios LLC neptunestudios.info OUR STAFF************Lizah van der Aart • Sarah Berman • Cameron DukeArcadi Garcia i Rius • David Goldenberg • Melissa HayesAlex Reich • Henry Reich • Peter ReichEver Salazar • Leonardo Souza • Kate YoshidaOUR LINKS************Youtube | youtube.com/MinuteEarthTikTok | tiktok.com/@minuteearth Twitter | twitter.com/MinuteEarth Instagram | instagram.com/minute_earth Facebook | facebook.com/Minuteearth Website | minuteearth.com Apple Podcasts| podcasts.apple.com/us/podcast/minuteearth/id649211176REFERENCES**************Brander, Robert W. “Rip Currents.” Encyclopedia of Earth Sciences Series/Encyclopedia of Earth Sciences, 1 Jan. 2019, pp. 1442–1447, doi.org/10.1007/978-3-319-93806-6_261Castelle, B., et al. “Rip Current Types, Circulation and Hazard.” Earth-Science Reviews, vol. 163, Dec. 2016, pp. 1–21, www.sciencedirect.com/science/article/pii/S0012825216303117, doi.org/10.1016/j.earscirev.2016.09.008Leatherman, Stephen P. “Undertow, Rip Current, and Riptide.” Journal of Coastal Research, vol. 28, no. 4, 1 July 2012, doi.org/10.2112/jcoastres-d-12-00052.1Masselink, Gerd, et al.

It can be measured in flashes per km2 per year.- Convergent windflow:- Coastal breeze: is the movement of air from the ocean to the land (onshore breeze) or from the land to the ocean (offshore breeze). The direction of the breeze is determined by the temperature difference between the land and the water.- Convective instability: is a meteorological term that describes the atmospheric condition favorable for the development of convection, which is the vertical movement of air. This instability is a key factor in the formation of thunderstorms and other convective weather phenomena.SUPPORT MINUTEEARTH**************************If you like what we do, you can help us!:- Become our patron: patreon.com/MinuteEarth- Our merch: http://dftba.com/minuteearth - Our book: minuteearth.com/books - Share this video with your friends and family- Leave us a comment (we read them!)CREDITS*********Esther Ikoro | Writer and Narrator (@SeeYouOutsideShow)Ever Salazar | Writer, Illustrator and DirectorLizah van der Aart | Illustration, Video Editing and Animation Nathaniel Schroeder | MusicMinuteEarth is produced by Neptune Studios LLC neptunestudios.info OUR STAFF************Lizah van der Aart • Sarah Berman • Cameron DukeArcadi Garcia i Rius • David Goldenberg • Melissa HayesAlex Reich • Henry Reich • Peter ReichEver Salazar • Leonardo Souza • Kate YoshidaOTHER CREDITS*****************Catatumbo Lightning Footage by Paolo Costa / Shutterstock.comOUR LINKS************Youtube | youtube.com/MinuteEarthTikTok | tiktok.com/@minuteearth Twitter | twitter.com/MinuteEarth Instagram | instagram.com/minute_earth Facebook | facebook.com/Minuteearth Website | minuteearth.com Apple Podcasts| podcasts.apple.com/us/podcast/minuteearth/id649211176REFERENCES**************Albrecht, R.
