Okay kiddo, let's talk about polar seas! When we say "polar", we mean the very tip-top and bottom of the Earth, near the North and South Poles. That's where the polar seas are located.
Now, these polar seas are very different from the oceans you might see at the beach. They are super cold, with icy water that can freeze even solid! In fact, during the winter months, the polar seas can be surrounded entirely by ice, forming what we call an "ice cap".
The creatures that live in the polar seas are also very different from the ones you might see in warmer oceans. They have adapted to survive in the icy water, with special features like thick fur to keep warm and blubber to stay buoyant.
One really cool thing about the polar seas is that they have a big impact on our planet's climate. You see, the polar ice helps reflect sunlight back into space, which helps keep the Earth cooler. But as the Earth gets warmer, the polar ice is melting faster than ever before, which could cause some big problems for the planet.
So, to sum it up, polar seas are located near the North and South Poles and are very cold with lots of ice and unique animals. They also play an important role in regulating the Earth's temperature and climate.
