Have you ever wondered what makes the ocean move? Well, for the most part, the ocean moves according to the tides, which cause the ocean's water levels to rise and fall. This is why sometimes you can see tide pools during the low tide, and sometimes those tide pools are hidden under the water (high tide). What causes high and low tides? Just take a look at the picture below:
Yes, it's true! Tides are most strongly affected by the moon. Wind, weather, and even the sun can affect tides, but for the most part, the moon is what affects the tides. The moon's gravity pulls the ocean water towards it, causing two big bulges of water - one that is being pulled out towards the moon and one that is trapped on the other side of the Earth. This is called "tidal force," and the bulges are called high tides. As the Earth rotates, it passes through two high tides (bulges) and two low tides everyday. This means you have two chances each day to go out and visit the tide pools!
