ELI5: Explain Like I'm 5

Sea

The sea is a really big area of water that covers a lot of the Earth! It's kind of like a giant swimming pool, but much much bigger. The sea is so big that people have only explored a small part of it.

The water in the sea comes from rivers, rain, and melting ice from the North and South poles. Sometimes, the water can be very cold or very warm, depending on where you are in the world.

There are many different creatures that live in the sea, like fish, whales, dolphins, and even some tiny animals you can't see. They all have different shapes, sizes, and colors.

When you go to the beach, you can see the sea! You can swim in the sea, build sandcastles, and even collect seashells. Just remember to be careful and always have an adult watching you. Also, it's important to keep the sea clean by not littering or polluting it. The sea is a beautiful place and we should take care of it!
