It actually curves, on the average, although locally it can be bowl shaped or hill shaped.
If the earth, or any large portion of it were flat, flat then the "horizon" would not be what we see now - instead of being an edge at a certain distance that depends on the height of the viewer, the distance would just go on and on fading into the pollution or just wavering of heat moving the air at a distance.
To actually see the curve one has to go up to about 40,000 feet to see it through the air above the clouds and local landscape.
