Gravity pulls everything toward the center of Earth. But not all parts of Earth are the same, some areas are heavier, like mountains or dense rock layers. This makes gravity pull a little stronger in those spots, making Earth look more like an orange with bumps, instead of a perfect ball.
Examples
- Imagine Earth is like a spinning ball of clay, it pushes outward at the middle and flattens at the top and bottom.
- If you spin an orange on a table, it bulges in the middle and becomes flatter on either end, just like Earth!
- Mountains are heavier, so gravity pulls more strongly there, making Earth look slightly bumpy.
