There is no such thing as an "ormal curve". And a Normal curve IS symmetrical!

A curve is so strong because when you apply a force on top of the curve the weight of that forced is transferred to the bottom parts of the curve which makes it really strong like bridges that use arcs
they curve because they have a heavy filling inisde that makes it curve

A curve
A normal curve, also known as a bell curve, is symmetric around its mean, indicating that data points are evenly distributed on either side, with most values clustering around the center. In contrast, a skewed curve is asymmetrical, meaning that it has a tail extending more to one side than the other; in a positively skewed curve, the tail is on the right, while in a negatively skewed curve, it is on the left. This skewness affects the mean, median, and mode of the data distribution, leading to different interpretations of the data's central tendency.
Asymmetrical
If you mean horizontally asymmetrical there are 15: BCDEFGJKLNPQRSZ If you mean vertically asymmetrical there are 17: AFGJLMNPQRSTUVWYZ
Now it is considered by most scientists that the universe is asymmetrical.
Meniscus
A gradual change in the gradient (slope).
I think the earth is wobbling on its axis and it makes the tracking lines appear to curve when they are laid over the map.
