Earth curvature

Earth curvature refers to the fact that the Earth is not flat but rather a spherical shape. This means that as you look further into the distance, objects appear to dip below the horizon. For example, when a ship sails away, it gradually disappears from the bottom up, rather than shrinking uniformly. The curvature is also why we observe different stars in the night sky based on our location. The Earth's roundness is confirmed by satellite images and the way gravity pulls objects toward its center, creating a balanced spherical shape.
