Why does the ocean have tides?

Have you ever wondered why the ocean creeps up the beach and then slides back out every single day? It is not magic—it is gravity! Join Mira and Finn as they uncover the wild secrets of the sea. You will discover how a giant rock floating in space—the Moon—actually pulls the Earth's water to create high and low tides! We'll even learn what happens when the massive Sun joins in for a giant game of tug-of-war. But the adventure doesn't stop at the sunny beach! We are taking a high-tech submarine dive straight down into the freezing, pitch-black Midnight Zone! Did you know there are fish that make their own light? Meet the wild anglerfish with a glowing, bacteria-filled fishing rod growing right out of its head! Plus, you'll come face-to-face with the legendary giant squid, an enormous creature with eyes the exact size of a dinner plate! From glowing ocean predators to the unbelievable crushing pressure of the deep sea, you will never look at the ocean the same way again. Grab your submarine gear and let's dive in!
