We are told that we only have tides in the oceans and seas because of the moon so why do we only see the moon once a day but we have two tides?

Yea, the moon's gravity pulls on our oceans and moves them (quadrillion tons of water), yet clouds and atmospheric vapor doesn't get pulled into space. Man people can't think. Thanks for the explanation though....lol
Add to that the emptiness of space, with zero pressure, how the atmosphere of the Earth isn't stripped away in a nano-second.
And gravity, because we live on a molton ball of iron, yet jupiter and saturn have gravity but are gas giants. Let me repeat....GAS giants. No iron ball.
Yea, and comets are broken up by the sun's radiation melting their outer shell and spewing debris making a comet "tail" but saturn and jupiter don't have tails and are 100% gas (with no iron ball)...
And that sun produces radiation at such a high level that our boys rode in an aluminum foil cage and didn't get cooked for 6days, nor did their cage explode from the pressure difference of zero atmospheric pressure in space, cuz, you know aluminum is some strong stuff.
But yea, the van allen belt is radiation and temperatures are up to 5000 degrees but you know that aluminum foil reflects that heat and it's all good.
LOL
The reason the atmosphere doesn’t fly off into space is because of gravity, which isn’t caused by the metal in the core of the earth but by mass. The more massive something is the more gravitational pull it has. Keep in mind the sun technically has to solid core but the fact that it’s something like 90% of the solar systems total mass keeps everything in orbit. Also solar radiation isn’t that bad when you consider the sheer distance between earth and the sun, sure you’d get cooked if you went to mercury but the moon? Not so much, the temps only go up to a couple hundred degrees, and can be compensated for by cooling systems. As for the integrity of aluminum, yeah it’s pretty strong, everything from submarines to fighter jets have been made from the stuff, hell F-22s are partly plastic. Also the Apollo capsule was only pressurized up to an equivalent altitude of 20,000ft so the designers did actually have a concern but it was later found to be unfounded. I don’t know where you are getting the 5000 degrees from as I don’t think there is anywhere in either earth or lunar space where temps get that high.
Jupiter and the gas giants have solid cores, larger than all of earth. That provide the dense mass needed to keep their gas from floating away. The sun is also mostly gas, and by your reasoning then should also dissipate into space.
Also the van allen/ ionosphere does a hell of allot to keep out atmosphere put.
The reason why the atmosphere ( which do have a tide) isnt as effected by tides as much as the oceans is the fact that gravitational pull is proportional to the masses involved. Therefore the earth oceans have a stronger gravitational pull than the atmosphere. Also due to inverse square law. As the distance between two gravitatioal bodies increse the gravitational force decreases exponentially. So that means that the earths gravitational pull on the atmosphere, oaceans and us is way higer than that of the sun, even though the sun is way bigger, and why we all dont float away.
The tides are a wave. The oceans are not being pulled straigt up and down, they are more sloshing back and forth in rythem with the sun and moons gravitaional influence. Almost like how if you put a glass of water on a table and than tilt the table back and forth sligtly, it would begin to slosh back and forth creating a wave.
Similarly as the reltive strength of the moon and suns gravitational pull rythmically ocillates with the elipical orbit of the moon and rotation of the earth, ( inverse sqare law) it creates just enough force to cause the oceans to slosh a tiny bit - the tides. If this was not true than why are tidal predictions perfecly accurate? Im a captain and use them daily wit zero discrepancy.
Also the tide is highly influenced by ocean topography. In the open ocean the tidal range only a few inches. It is only due to the venturi effect ( the velocity of a fluid increases as it flows through a constriction) that they become pronounced near shore. Thats why the tides in a fjord can be 15 ft + and only a couple feet on a broad open coast.
