Tides happen because the moon pulls on Earth’s water, making it rise and fall like a wave.
Imagine you're playing with a big ball (Earth) and a smaller ball (moon). The smaller ball tugs at the bigger one, and where they’re closest, the water gets pulled up, that's high tide. On the opposite side of Earth, it’s like when you pull on one end of a rope, the other end moves too! So there’s another high tide on the far side.
Now imagine two kids tugging on a jump rope at different times. Sometimes they’re both pulling in the same direction, that makes the rope go up more, just like two high tides happening at once. Other times, one kid pulls and the other lets go, that’s when there's only one big wave of water, called high tide, and then it goes down to low tide.
At different places on Earth, like a beach or a lake, how strong the moon’s pull feels depends on where you are. Some spots get more pulls than others, that’s why tides can feel bigger in one place and smaller in another, just like when you’re closer to the ball or farther away.
Examples
- A person living near a river feels the tide pull differently from someone on a beach.
