(FOX 32 NEWS) Is the Earth round? A surprising number of young people are not totally sure.

A YouGov survey of 8,215 American adults found that just 66 percent of young adults (ages 18 to 24) firmly believe the Earth is round.

The survey also found that the more religious a person is, the more likely they are to believe the Earth is flat. YouGov said that 52% of "Flat Earthers" consider themselves to be "very religious."
