The Earth is not perfectly round, it’s more like a squished orange, and we use geoid and ellipsoid to help us understand its shape.
Imagine you're playing with clay. If you roll it into a perfect ball, that's like an ellipsoid, smooth and even. But if you press your hand gently on one side, the clay squishes down, making it look more like the Earth. That squished version is closer to a geoid, which is what the Earth really looks like when you consider all the hills, valleys, and oceans.
The Ellipsoid
Think of the ellipsoid as a smooth orange, nice and even. Scientists use this shape because it’s easier to work with when they’re making maps or calculating distances. It's not perfect, but it helps simplify things.
The Geoid
Now imagine you're swimming in a pool that has different depths everywhere, some parts are deep like the ocean floor, others are shallow like a lake. That wobbly shape is the geoid, it shows the real, uneven surface of the Earth as if it were covered with water.
So, while an ellipsoid helps us draw maps easily, the geoid shows how bumpy and interesting our planet really is! The Earth is not perfectly round, it’s more like a squished orange, and we use geoid and ellipsoid to help us understand its shape.

- If Earth were made of water and perfectly smooth, it would look like the geoid.
