Imagine you are playing with a big ball of Play-doh. You can roll it, smash it and shape it any way you want. Now let's say the ball of Play-doh is the Earth - the place where we live. But here's the thing, the Earth is not just made of Play-doh; it's made of different layers like the crust, mantle, and core.
Sometimes, the Earth's layers move around a little bit. We call this movement "tectonic plates." These plates are like big pieces of the Earth's crust and they move around on a soft part of the mantle like how you would move a big piece of cake on a plate.
When the plates move, they can rub against each other, creating earthquakes and volcanoes. But what if we could make the Earth's layers not move around so much? That's where contained Earth comes in.
Contained Earth is like putting a big glass dome over the Earth. It helps keep the Earth's layers from moving around too much. Scientists have done experiments to see if contained Earth could work, and it seems like it could be a good idea to help control what's happening to the Earth's surface.
But here's the tricky part - creating contained Earth would be really hard and expensive. We would need to build a dome that's big enough to cover the entire Earth, and we would need to make sure that the dome doesn't block the sun's rays or stop us from getting the air we breathe.
So while contained Earth might be a good idea, we're just not sure it's something we can actually do.
