the earth is round. proof? the coriolis effect. its the reason hurricanes spin opposite directions north and south of the equator. this wouldnt happen on a flat earth but would on a round earth. this link here is a back an forth between myself and flat earthers that has yet to be proven wrong. http://imgur.com/gallery/1oKq4 . also, how do those in the artic and antartic circles experience prolonged periods of weeks of darkness or daylight no matter the time of day during certain seasons? i have friends in alaska and norway who experience this. this wouldnt happen if he earth was truely flat.
