Answer 2

Curvature of the earth :

As we don't notice it in our everyday lives, it has to be quite small. Most sources consider 8 inches per mile as the most accurate estimate. This means that for every mile between you and an object, the curvature will obstruct 8 inches of the object's height.

Horizon :

The line where the earth and sky appear to meet.
