Otherwise, the sheer weight of the high floors would make the building collapse into itself. One of the fundamental characteristics of gothic architecture was its height. New building techniques (such as the flying buttress, detailed below) enabled architects to spread the weight of taller walls and loftier towers. This all meant that gothic buildings could, quite literally, scale new heights.
Adult snapping turtles can stay under water for 40-50 minutes. I have a baby snapper and he stays under for about 10-15 minutes.
