I mean, rain doesn't have salt in it, so when it rains wouldn't it get diluted? How does it stay salty? What causes the salt?

The chemistry of the ocean is buffered by water-rock interaction within sediments and at mid-ocean ridges. No lie.
If salt simply came from erosion, then the salinity of the ocean would increase with time, and this does not happen except in isolated basins where it is caused by evaporation.

It is true that solar salt is produced from evaporation of sea water, but it is a more involved process than just letting the sea water dries in the sun. After this initial step, the salt crystals are gathered, washed and crushed before it can be used. Solar salt typically is not fit for human consumption.

The ocean didn't use to be salty. Millions of years ago, rivers began dumping water containing minute traces of salts that built up, that's why it's so salty. The salts follow the water cycle only at the liquid and ice part.

well salt exist as natural reserves inside caves mountains and even at some river beds... the water just washes it downstream (even underground water) in small doses and with millions of years passing by those minerals including the salt accumulate in the sea and made it salty... above of that the sun evaporates the sea water and again the evaporated water condenses and falls as rain and more water brings along more minerals in the sea... this cycle has been going on for million of years so u may imagine the amount of salt that has accumulated in the seas.

Salts come from leaching of rocks and soil as the rainwater passes through as ground water. The groundwater becomes surface water and reaches the sea by means of rivers and streams. It stays salty because during evaporation, salts stay put while the H2O rises into the atmosphere.

the rain washes the land dissolving salt in the soil and Rivers carry it to the sea,where it builds up
when the ocean evaporates into the clouds it leaves the salt behind and it starts all over again

there is salt in the sand, and salt in the rock sediments, so when the waves crash against the rocks, salt is put in the water. there is so much salt in the water, because over time it just builds up. there is too much salt in the sea for rain water to dilute it.

There are entire mountain ranges in the seas - made up of rock that contain salt. Also all the rock beneath the sea floor, etc... is constantly leaching out into the water.

i concur with Anna's answer. i might add that there are naturally occurring deposits of salt that are leached by ground water.

it comes from the sea eroding the rocks and coast line and thats where salt come from................................i think
