I got send here by my geography teacher.
You need an English teacher lol. Sent.
Same
BAHAHAHA smm
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.
That was an excellent, info-packed explanation! Thank you.
This is the best explanation I got for waves. I also got many more and interesting information for waves.
3:05. That's so fetch.
stop making fetch happen. it's never gonna happen.
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.
👏
Great pun my friend
Damn 😂🙌
They shore did I sea what u did that
😂😂😂😂😂
This is the best explanation of waves.
:D Im suppose to listen for this for school since everyone in CORANA is homeschooling
Chelsea Tovar same
Nasheed Edwards omg twins
waves are awesome!! :D
Louis Murphy yEAHHH :D
It is the same with me :)
thanks, that was much more entertaining hearing it from you
Awesome video! looking forward to more videos
The Abyss you’re welcome! Have a dig around our archive - loads of brilliant questions answered!
Soooo interesting!
Awesome ,,,,BBC ALWAYS CREATE AWESONE VIDEOS
about time I searched this up after wondering about it for a couple of years.
Thank you
Makes me wonder then why haven’t surfers taken the initiative to terraform some of the shoreline land just under the water In order to create amazing surf parks! It seems they could make one end beginner surf territory and the other in advanced surf territory.
suppose assuming - there are no winds - can a wave still exist, albeit at a low level???
probably. Boats, underwater creatures?
How interesting.
Is it possible for wave breaks to happen in quantum fields?
camassa-holm equation models breaking waves
Great video
JaMar Thomas thanks!
I mentioned wind to someone but moon was mentioned.. I've seen foamy water in sea..Thank you
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!
great vid!
Cheers! 👍
Why do lily pads have a triangular notch "cut" out of them?
Because they do it’s normal
Because Mojang said so
Formation of ocean waves. only this video to be referred on youtube, 11th May, 2022.
Hmm very interesting
Anyone else hearing a weird pinging from your left side?
That's a single tone from the music that is only being played on the left side of the recording.
so why do most rivers dont have waves similar to that of beaches? i mean wind is also present in the rivers right?
Rivers have some waves, but with less surface area to receive wind, im guessing they usually only get built up to capillary waves. And this is just conjecture, but I would think the fact the the river is flowing from o e place to another would affect wave formation.
I love how apologetics tend to sway a person's decisions in judgments.
I respect your theories however much with the high tides and lowering tides the ocean is constantly moving not blowing.
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
Correct me if i'm wrong, but I think no matter what in the Earth the particles want to be in equilibrium, in rest and not be disturbed (whole idea of inertia and all that). So naturally indeed these waves should die off before hitting land.
However, because of the pressure gradient present in the atmosphere and air, where air in high pressure regions would move to low pressure regions, there will be wind movement. The wind would continue blowing onto the ocean surface, causing friction between the wind (air particles) with the ocean surface (water particles). This thus causes the formation of the waves as explained in the video and with continuous wind movement, the wave would proceed on towards the direction of wind and the transfer of energy from the air particles to wind particles will continue.
Also, there will be waves (or wave trains) with higher wave energy who would absorb the waves with lower wave energy. This absorption of energy increases the amount of energy they hold, causing it to proceed onwards.
Also as explained in the video, as the deep water waves move to shallower regions and meets with resistance and friction from the change in seabed, the wave energy from below gets transferred to the wave above. And as the orbitals or wave particles below die out, the waves above gets unstable and will eventually break.
In light of having no wind or no other waves with energy, then the wave would die off before hitting the land.
I'm not too sure if my explanations are right, but I'm currently learning coastal morphology and this is what I've learnt about the waves and wave energy!
please do a video on underocean rivers pls
Next question : What causes the wind?
SeemsLegal - Trees
ibkillah lol
Heat transfer
when was the first blow of wind

nice

Keep up the good work guys
David Slattery cheers David!
Please tell me about planet 9 theory
You could cover the specific? That's my pacific subject!
stop being a pacifist
Lol
What about all the ship, boats and fish moving in/on the water? Don't they create waves also?
"if there is a pacific subject you would like us to cover" is that another pun?
I think it is 😏

What are these numbers on the top left..?

I don't know where you live Greg but where I'm from not a single a person I've ever met has thought a wave is created by the tides.
I was just curious
This has helped me a lot in understanding my humanities content
Why don't rivers have waves?
They do but theyre small. Its not enough space to make the wind make big waves
Someone wants to tell me what that number is on the top left with the symbol of atom next to it that appears every few minutes? (or Seconds )
babis8142 *cough* footnotes *cough*
We’ve added links to more info in the vid description for you 👍
good video but why the hell is this on trending with 20,000 views after 2 days?
Once a wave broke on my head and gave me 12 stitches inside my nose. I'll never understand how waves work.
Waves aren't random they come in patterns.
if it was wind why wouldn’t we have waves in ponds or swimming pools 🤔
hmmmm. Good question. If it was wind, why are there no tsunamis in my swimming pool? It doesn't.. make... SENSE
scale
it was wind, traveling for kilometers! I do not know your swimming pool but good luck with that

Hello guys! Xp
I believe that waves are caused by oscillating pressures in weather systems that raise and drop the ocean surface. It's the only way I can account for the energy I'm seeing.
Yes its air pressure that causes wind that causes waves.
If you have ever seen a wave you would know wind didn't create it. Must be one of those clowns that believe the oceans are rising and the earth is warming because we don't give money to central banks to cool it down.
@@seandaniels9168 Heat causes the air to rise and that displacement creates a low pressure and the surrounding air pressure replaces the low pressure; and that's wind. I believe there is pressure modulation in these systems that raise and low the surface of the water that create these waves that travel for miles. Kind of like when you blow air over the tip of a straw you will notice the water rising in the straw. If you blow side to side over the straw the water would raise and lower with the frequency of your head movement. There is nothing on the surface of water that can harness the energy of wind. Science likes to make shit up until someone else figures it out.
Now it's only fair that you explain wind.
He should. But the answer is drastically different temperatures and pressures around the globe. It's always trying to equalize into a still, constant temperature all around the world, but it never does and never will
Hm, analogous to harmonics I would assume
where does wind come from?
The windhas no place where it was born (u know what I mean) because the heat of from the sun and so cause the suns heat is heavier than cool air the wind is produced because warm/hot air is lighter than cool air (heavier than warm air)
Then why do big rivers does not have waves as wind is everywhere?
SURYA TEJA because in rivers, there exists a floor, which prevents swell. And also because there are really agressive storms mid ocean, and not in rivers.
Havent you seen in big lakes that there are small waves?
Good british explanation

Effortless English Why? Do you have a problem with me ending sentences with prepositions?
what do you mean xD
and why would i have a problem with ya lol
wind+moon. i'd assume before watching.
Nope, It was Kraken and Mermaids, but thanks for playin.
Why is 1 in every 7 waves bigger?
How can wind create the energy a wave has below the surface?
Gravity.
who the hell thought it was tides instead of wind?
What do the numbers in the top left of screen relate to please?
Eric Brett Jones look at the description. There are some links with the numbers. So if you want more information about it you can look in there.
Thank you Geert. I had tried that but they are tenuous links, not only in their inconsistent numbering but except for link 4 they seem to bear little relevance to the specific passages to which they refer.

When the ocean got to the party it was shore happy. When the ocean entered the party, it’s friends waved at the ocean. After the party, the ocean got into its tide-y bed and went to sleep.
The next day. The ocean drifted out of its bed, and then brushed its teeth, after that it“washed ”its face and went to its car. When the ocean was driving, it “crashed” into someone. The ocean is dead now. I guess you could say it was a “Wipeout”
Just get to the point 🤦♂️
Then search on google instead of youtube. CZcams would be such a great place if you would just get answers like ‘’wind causes waves because of enery’’ *video ended*...

Too talky, it was like 2 minutes before you finally started showing pictures of waves and then it wasn't even real pictures
Honda makes them.
Well where does wind come from? God huffs and puffs and blows it at the ocean. Checkmate, atheists.
It's actually Allah farting. Checkmate Christians

CZcams takes a while to refresh the video statistics.
How do waves still work? Considering your model is flat. We live on a globe... What are you a FLAT earther?
stop adding “- Earth Lab” to your videos and ull be getting a lot more views
This video is not epic
The British accent is very boring

Meh I find this channel too hand-wavy with your discussion on scientific topics. The choice of language is also poor and lacks accuracy. Unsubbed. I much prefer PBS Spacetime/PBS Infinite series and Veritasium. Even Vsauce is more accurate, despite its overexaggerated style.
