Tidal force

So, have you ever played with Play-doh? And have you ever noticed that when you roll it into a ball, it gets squished a little bit on the sides? That's kind of what happens to the Earth when it gets near really big objects in space, like the moon or the sun. They're so big that they create this thing called "tidal force," which basically means they pull harder on one side of the Earth than the other.

This can cause the water in the oceans to bulge out in certain places, creating tides. When the moon is closest to the Earth, it pulls on the water on one side of the Earth more than the other, creating a high tide. And when the moon is on the other side of the Earth, the water bulges out in the opposite direction, creating another high tide.

But tidal force doesn't just affect the water - it can also affect the land and even the atmosphere! It can cause the Earth to wobble a little bit, and it can also cause the land to slightly shift and move.

Overall, tidal force is the force that big objects in space like the moon and the sun create on the Earth, which can create tides and other effects.
