Is the force of the water on the piers the same at the water surface as it is 30m below the surface?
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.
Can water molecules evaporate at the surface or below the surface?
Water molecules can evaporate from the surface of water, where they gain enough energy to overcome surface tension and escape into the air. Below the surface, water molecules can also evaporate through a process known as sublimation, where molecules transition directly from a solid to a gas, although this is less common.
Ground water exists below the surface of the earth?
Yes, groundwater is the water found beneath the Earth's surface in the pores and spaces of soil, sand, and rock formations. It is a valuable natural resource that is often used for drinking water, agriculture, and industrial purposes.
Why the surface layer of water in the poles is colder than the layer just below it yet the colder layer floats on top?
Due to the anamolous behaviour of water, the surface water being cooled by the external environment falls below 4C and begin to expand. when this surface water molecules expand they rise to the top due to a decrease in density as compared to the water below the surface. the cooler the temperature henceforth, the more the expansion of the surface water molecules till it solidifies to become ice. this surface ice then acts as an insulator and prevents the exchange of heat between the environment the water molecules just below it, thus maintaining the temperature of the water below the surface as constant.
What is Water that is below surface?
Ground water, or an aquifer.

How do you calculate the density of an irregularly shaped object which is less dense than water?
Force it below the surface of water and measure the force required.
Why does a cork below the surface of water rise to surface?
A cork is less dense than water, so it displaces an amount of water equal to its own weight. The upward buoyant force exerted by this displaced water is greater than the downward force due to gravity, causing the cork to rise to the surface of the water.
The surface tension of water is caused by the water molecules on the surface experiencing?
unequal forces of attraction from the molecules below and beside them. This creates a stronger cohesive force among the surface molecules, causing them to pull together tightly and minimizing the surface area, resulting in surface tension.
Which fundamental force contributes to pressure in both water and the atmopshere?
The fundamental force that contributes to pressure in both water and the atmosphere is gravity. Gravity creates a force that acts on the particles in water and air, causing them to press down on the surface below and thereby creating pressure.
Is there buoyant force on an object at the bottom of the ocean?
As long as any part of the object ... doesn't matter how much ... is below the surface of the water ... doesn't matter how far ... there is buoyant force on it.
Is there bouyant force on an object at the bottom of an ocean?
As long as any part of the object ... doesn't matter how much ... is below the surface of the water ... doesn't matter how far ... there is buoyant force on it.
Is there buoyant force on an object at the bottom of an object?

When you swim what is the force of the water which pushes you toward the surface?
The buoyant force pushes you toward the surface.

What is the density of water Why doesn't air bubble rise to the surface of a glass of water?
The density of water is approximately 1 g/cm3 at room temperature. An air bubble in water doesn't rise to the surface immediately because its buoyant force is not strong enough to overcome the cohesive forces between water molecules, which tend to keep the bubble trapped below the surface. Once the bubble accumulates enough buoyant force or is disturbed, it will rise to the surface.
