Does the saltness of the sea increases as the time passes?

As water flows in rivers, it picks up small amounts of mineral salts from the rocks and soil of the river beds. This very-slightly salty water flows into the oceans and seas. The water in the oceans only leaves by evaporating (and the freezing of polar ice), but the salt remains dissolved in the ocean - it does not evaporate.

So do the remaining water gets saltier and saltier as time passes?

If the earth is really millions of years old, then why isn't it all dust?

It is a scientific fact that all the rocks would be dust by now. Why do you believe evolution just because Satan told you to? If Stan told you to jump off a cliff would you do it?

If a helicopter rmains stationary at the same place for say 2 hrs,any change in relative position wrt earth?

point is as helicopter remains stationary for two hours, the earth under it rotates ( its natural axis rotation), the points /articles under it will change its position wrt helicopter or not? Say helicopter is lifted from the top of a hotel then even after two or more hours of its lift , it will still be above the same hotel? If yes, what about the rotation of earth on its axis?
