It can be normal as your uterus is still expanding to accomodate your baby. However if the feeling is painful or out of the normal for you or if it's associated with decreased fetal movement you should contact your doctor right away. Either way a call to your doctor or midwife would be a good idea.
It is normal for the sides to bow to the middle of the pool, as the pool fills the sides will right themselves by the weight of the water, it happened to me but it is normal.
One is Anticline, which is a semicircle that is like a hill but stop in the middle or the way down. A Syncline, is a semicircle with pressure at both sides. A Monocline, is a semicircle that goes flat with pressure
When pressure is put on the sides of a plate, a earthquake might form!

High pressure is stronger. Pressure is caused by the gas particles in a container hitting the sides of said container. At high pressure, the particles hit the sides of the container much more and therefore are pushing harder on the sides.
The Eustachian tube
This is the tube that connects the ear with the throat. Its function is to equalize air pressure on both sides of the eardrum to keep the eardrum from rupturing and to reduce pain that may be felt when air pressure is reduced. When a person yawns or swallows, the eustachian tube opens, and some of the air in the middle ear may pass into the throat, adjusting the pressure in the middle ear to match the pressure in the outer ear.
That the pressure on two sides of a non-permeable barrier has been made equal on both sides.Through free air travel between the middle ear and nasal passage via the Eustachean Tube.
When a tire is properly inflated it will be level to the ground. Over inflated and the middle of the tire has the most pressure on the ground. Under inflated and the sides of the tire have the most pressure on the ground.
It is higher on the sides.
Gas pressure
If you mean it by its atomic shape, its a hydrogen atom at both sides and an oxygen atom in the middle. But if you mean it by its normal appearance, then it can take up any shape.
