Where Do Waves Come From? Earth Science

Where do waves come from and how are they formed? Greg Foot explains.

Here at BBC Earth Science we answer all your curious questions about science in the world around you. If there’s a question you have that we haven’t yet answered or an experiment you’d like us to try let us know in the comments on any of our videos and it could be answered by one of our Earth Science experts.

I got send here by my geography teacher.

This is the best explanation of waves.

Thanks, getting my 9yr old surfer and dad coach to understand the physics of waves. As yesterday's gale brought in awesome waves for today.

[shivanjaliganbavale]

This is the best explanation I got for waves. I also got many more and interesting information for waves.

[joelamontagnejr]

That was an excellent, info-packed explanation! Thank you.

I appreciate the video. The class I'm in has gotten rather annoying due to no interaction from my classmates or my instructor, and I wasn't expecting to be entertained by an assigned video. Wonderful explanation, and interesting.

What did one ocean say to another? Nothing they just waved.

Why do lily pads have a triangular notch "cut" out of them?

[studywithalison]

This has helped me a lot in understanding my humanities content

[vishalramesh]

suppose assuming - there are no winds - can a wave still exist, albeit at a low level???

[leviathan]

Is it possible for wave breaks to happen in quantum fields?

[archthesheep]

I think a video on anaerobic digestion would be interesting guys, and how it can be used to make biofuels. This was a great video, explained very well!

I got a question. Do the waves eventually die off before hitting land? it sounds like they don't but hows that possible? don't they lose energy after a long journey? shrinking in size ever so slightly with each movement? I hope I was clear on my question and maybe somebody can answer it? Thanks
