How Does the Ocean Stay Warm in Winter?

The ocean is like a giant blanket that holds heat. When the sun shines on the water, it warms up. Even when winter comes and it’s cold outside, the ocean doesn’t lose all its warmth right away. It takes time for the cold air to cool down the warm water, so the ocean stays warm longer than the land does.

Why is this important?

When the ocean stays warm, it helps keep the Earth a bit warmer too. This means animals and plants can still live in the sea even when it's chilly on land.
