When you look at at the ocean, ever notice how the water and the sky meet at your eye level, the horizon line?

Perspective forces everything towards this central point that meets at your eye level. This central horizon line could be a few miles away to 1000s of miles away depending on your altitude.

This means that the ground is forced upwards to meet your eye, anything beyond this meeting point of your vision will disappear as if it was going behind something, when in reality it is being blocked by your perspective.
