The sea is like a giant, wavy blanket that covers a big part of our Earth. It’s full of water and stretches out really far, so much that you can’t see the other side! The water in the sea is salty, like the salt you might sprinkle on your food. This salty water is home to many creatures like colorful fish, playful dolphins, and huge whales that swim and play beneath its surface.

Think of the sea as a big, blue playground for these animals. Some creatures live near the top where the sun shines bright, and others live way down deep where it’s dark and mysterious. The sea also has waves that dance and splash onto the shore, making a fun sound like a gentle roar. These waves can be tiny like ripples or big like mountains.

The sea is also like a giant bathtub for our Earth. It helps keep our planet cool and gives us rain when the water rises up to the sky and comes back down as rain. People love to visit the sea to swim, build sandcastles, or just listen to the calming sound of the waves. It’s a special place full of wonders and surprises!
