The Moon pulled on Earth even before there were oceans, like a big invisible friend tugging on a toy.
Before Earth had oceans, it was mostly dry and hot, kind of like a sandy beach without the water. But the Moon was already up there, circling around Earth, just like how you might go around your best friend during playtime.
The Moon’s gravity is like a gentle but strong hand that pulls on Earth. Even though there were no oceans to splash around, this pull still made some changes, maybe making the ground shake a little or causing small rocks to move here and there, just like when you bounce a ball and it moves around on the floor.
As time went on, Earth cooled down and water appeared, forming oceans. Then the Moon’s pull had something bigger to work with, the oceans started to rise and fall, creating tides that we know today, like waves in a bathtub when you move your hand back and forth.
So even though there were no big waves or splashy fun before, the Moon was already playing its part, just in a different way!
Examples
- A giant moon pulls on Earth's surface, causing rocks to move like water even without oceans.
- Imagine the moon pulling on a dry landmass as if it were a liquid.
