Bathymetry of Giant Waves micro-lesson

Do you struggle with balancing your kids’ screen time with their education? Say hello to 1Question, the app that solves this problem with a fun twist! Our app lets your child earn screen time minutes in their favourite apps by watching educational videos and correctly answering quiz questions. And the best part? You get to decide which apps to lock behind learning using 1Question. 

Learning time​

Kids learn by watching short, engaging video lessons.

This lesson is about the bathymetry of giant waves. Some surf waves can be huge monster waves. The biggest waves recorded have been 100 feet tall like this one being surfed by Justine Dupont. I will take a look at these three famous big wave surf spots: Mavericks in California, Pe’ahi in Hawaii, and Nazare in Portugal. And what about the ocean floor or bathymetry makes these waves so big? All three have a very deep underwater canyon next to the surf spot. Mavericks’ 100 feet deep underwater canyon creates waves that can be up to 20 to 60 feet. The canyon at Pe’ahi also goes from 100 feet deep to 20 feet deep and can also create waves that can be 20 and sometimes 60 feet tall. Next, I'll talk about the big wave at Nazare. Nazare’s canyon is 16,000 feet deep and channels the waves to where the waves break, and this creates a monster 100-foot wave. These are three examples of what it looks like under the ocean of these giant waves.
