air pressure
The atmosphere exerts pressure on all objects and surfaces within it, including buildings, people, and the Earth's surface. This pressure is a result of the weight of air molecules above pressing down on objects below.
No, it would be less due to compression by weight of the surface area water. Every so many feet (meters) down, another "atmosphere" of pressure is exerted. Ergo, water at the seabed would exert more pressure on the pier than the water at the surface.
Yes, solids can exert pressure on the surfaces they come into contact with due to their weight or force applied. This pressure can vary depending on the amount of force exerted and the contact area with the surface.
The pressure increases as you go deeper below the Earth's crust due to the weight of the overlying rock and other materials. As you move deeper into the Earth, the layers above exert a greater force, causing the pressure to rise. This phenomenon is known as lithostatic pressure.
Yes, the pressure inside a bubble is greater by the amount 4*sigma/R where sigma is the surface tension and R the bubble radius. This is also known as a Laplace pressure, discovered by the French scientist Pierre Simon de Laplace. The factor of 4 comes from the fact that the bubble has two sides, both of which exert a force on the air inside.
the earths surface.
The diameter of the water column does not affect the pressure.It is the height of the column that determines the pressure at the base.(and also the barometric pressure and temperature).
The atmosphere exerts pressure on all objects and surfaces within it, including buildings, people, and the Earth's surface. This pressure is a result of the weight of air molecules above pressing down on objects below.
Yes. Atmospheric pressure is the pressure caused by air when it exerts pressure on the surface of earth.

Fluids exert pressure due to the weight of the fluid above pressing down on the fluid below. The pressure in a fluid increases with depth because of this weight. This is known as hydrostatic pressure.
Air pressure at sea level is considered high because the weight of the air above exert pressure on the surface. This pressure decreases as altitude increases due to the decrease in the weight of the air column above.

No, it would be less due to compression by weight of the surface area water. Every so many feet (meters) down, another "atmosphere" of pressure is exerted. Ergo, water at the seabed would exert more pressure on the pier than the water at the surface.

You will exert more pressure when you stand on your toes because your body weight is concentrated on a smaller surface area. This increases the pressure on the toes compared to when you are standing flatfooted with the weight distributed across a larger surface area.
Light does not have mass, so it does not exert a force by itself. However, light can carry momentum and exert a force on objects it interacts with, such as when light is reflected or absorbed by a surface. This is known as radiation pressure.
