How bad can a person's knowledge of geography be?

People who have never studied geography at all have no basic knowledge of location, distance and area; People who have studied basic geography but just don't know the places mentioned will have a rough but unclear imagination. For example, my high school geography level, my mother never studied geography for a day. We heard the name of a strange country together and were told that this country is in Western Europe. My reaction: the estimated area will not be very large, probably located in the plain, with time difference of 10 hour, temperate maritime climate or Mediterranean climate, and so on. My mother's reaction: no feeling. If you ask her if this country is close to Britain or America, she will look puzzled.
