Final Answer:
The ocean is salty because rainwater picks up salt from rocks and soil, rivers carry that salty water to the ocean, and over millions of years, all that salt has built up.

Explanation:
Let’s break it down step by step — like telling a story:
1. Salt is hiding in rocks and dirt on land. It’s not just in the ocean — it’s everywhere!
2. When it rains, the water doesn’t just fall and sit there. It flows over the ground and picks up tiny bits of salt from the rocks and soil — like a sponge soaking up flavor.
3. That salty water then goes into rivers. Rivers are like nature’s highways — they carry water (and salt!) to the big oceans.
4. The ocean doesn’t really “get rid” of the salt. It stays there. And every year, more salt comes in from rivers.
5. This has been happening for millions of years — so now the ocean is super salty!
Think of it like adding a pinch of salt to your soup every day. After a long time, the soup gets really salty — even if you only add a little each time.
And don’t forget — you need to draw a simple labeled diagram too! Maybe show rain → land → river → ocean, with arrows and labels like “salt picked up here” or “salt added to ocean.”
