Have you ever wondered why seawater tastes salty? The answer begins with rain. When rain falls on mountains and land, it flows into rivers. Along the way, the water dissolves tiny bits of salt that are hidden in rocks and soil. The rivers then carry this salt all the way to the sea.
In the sea, the sun causes the water toevaporate, but the salt is left behind. Only the water escapes into the air, while the salt builds up. This processhas beenrepeated for millions of years, and that is why the sea has become so salty. In fact, the ocean is still becoming a little saltier even today.
