The hailde component of salts (cl, fl, br, etc) is contributed to seawater mostly from volcanic processes. The continuous activity at the spreading ridges provides an almost constant supply injected directly into the water as gasses. Volcanoes and hydrothermal vents also supply quite a bit. These halides are then available to combine with ions like sodium and potassium (weathered from continental rocks and carried to the ocean by rivers) to form salts (sodium chloride or potassium chloride for example). Wikipedia has a great summary if you need more info.

The rain that falls on the land contains some dissolved carbon dioxide from the surrounding air. This causes the rainwater to be slightly acidic due to carbonic acid (which forms from carbon dioxide and water). The rain erodes the rock and the acid breaks down the rocks and carries it along in a dissolved state as ions. The ions in the runoff are carried to the streams and rivers to the ocean. Many of the dissolved ions are used by organisms in the ocean and are removed from the water. Others are not used up and are left for long periods of time where their concentrations increase over time.

the ocean doesnt get the salt but it is formed near the lower layer of the ocean bcz of the chemicals present and even there is no ozone layer in the deeper layers of oceans

the rain fall making streams that dissolve salts from the rocks .
the salt concentrate due to evaporation process

Sorry i don't know the answer, but such a good question.
Its probably caused by some sort of rocks rubbing together.
I am sure a boffin will answer this soon

actualy......the evaporation rate of water from the ....ocean surface is much more than that of the ........water entering into the ocean,,,,,thts why all the carbonate componds........left behind after the evaporation.........thts it frm where the ocean gets its salt
