How Do Some Waves Get SO Big?

TL;DR

Waves become gigantic due to underwater geological features, while MOVA globes use ambient light and the Earth's magnetic field for a stunning display.

Transcript

Hi, this is Kate from MinuteEarth. The biggest waves on Earth - those that are the height of entire office buildings - become truly gigantic because of what happens out of sight. That’s because waves don’t just sit on the surface; the waves’ energy can extend more than 1500 meters below it. Once a wave reaches shallow enough water, it makes contact... Read More

Key Insights

• 👋 Waves become gigantic due to the interaction between their energy, the shape of the seafloor, and the presence of underwater features like reefs and canyons.
• 👋 Undersea canyons are significant in generating massive waves by funneling and launching wave energy.
• 👋 The seafloor shape determines whether waves break or not, with abrupt changes playing a crucial role in compressing and intensifying wave energy.
• 🌍 MOVA globes are powered by ambient light and the Earth's magnetic field, resulting in a captivating display of rotating globes.
• 🧡 MOVA globes offer a range of designs, including customizable solar systems.
• 🌍 MOVA globes can be considered an innovative fusion of science and art.
• 😃 The cost of MOVA globes may be a potential drawback, but their unique features make them a joy to have.

Questions & Answers

Q: How do waves become gigantic on Earth?

Waves become gigantic due to the interaction between their energy, the seafloor shape, and underwater geological features like reefs and canyons. These factors can compress and funnel wave energy, leading to huge wave breaks.

Q: What makes undersea canyons significant in generating large waves?

Undersea canyons not only funnel massive amounts of wave energy into a narrow channel, but they also launch that energy over a shelf just before the shoreline. This combination creates intense and massive wave breaks.

Q: How does the seafloor shape affect waves?

The seafloor shape plays a crucial role in determining whether waves break or not. Gentle sloping seafloors gradually push wave energy above the surface, while abrupt changes like vertical angles or canyons compress energy, leading to powerful wave breaks.

Q: What powers MOVA globes and what makes them unique?

MOVA globes are powered by ambient light and use torque from the Earth's magnetic field. This unique combination of energy sources creates a stunning display of rotating globes. They come in various designs, including customizable solar systems.

Summary & Key Takeaways

• Waves on Earth can reach the size of office buildings because their energy extends below the surface and is affected by the shape of the seafloor.

• Underwater geological features like reefs can compress wave energy, leading to dramatic wave breaks.

• The biggest waves occur in places with undersea canyons that funnel and launch wave energy, creating massive breaks.
