If the continents are drifting, and rising or falling or being obliterated by catastrophic events of one sort or another, how com there is still salt water in the seas and oceans, and fresh water in the rest of the lands?

Because Sodium Chloride doesnt get evaporated. Or maybe.. I’ve not understood the question.
Why wasn’t it all blended and made into one aqueous substance eons ago? Why is fresh water and salt water distinct from each other?
ah.. Because they are essentially at different densities.. fresh water being less dense than salt water.
do you understand the water cycle? When water evaporates from the sea, and turns into clouds, it doesnt take the sodium chloride (salt) along for the ride. then it rains, usually more often than not, overland, because the land mass and resulting thermodynamic air currents will push the cloud higher into the troposphere until there isnt enough atmospheric pressure to maintain cohesion and the wator vapeur, reconsti tutes into droplets.. which fall as rain.. this ‘freshwater’ is obvioulsy above sea level, usually over mountauis and raised land.. will then trickle down, filter through the earth into underground rivers and eventually drain back to the sea, where it is mixed with salt water, to once again.. become brine. 70 percent of Earth’s drinkable water.. is held as ice in glaciers, north/south pole… (tho.. thats all melting now..)
Thanks for your informed reply. I was envisioning a scenario of massive disruptions of the current land mass versus ocean ratio, wherein the waters of the Earth are mixed. I suppose once stasis is reached, the natural processes you mention would take over until balance of salt and sweet is restored. Again thanks, and, for me, back to the drawing board,
