First of all, pressure is defined as force per unit area. In the case of a lake, the main force acting upon an object in the lake would be gravity, among others. At the surface of the lake, the pressure on the object would be the force that the column of air above exerts on it, divided by the area that the force is acting upon. On the other hand, the pressure on the object at the bottom of a lake would be the force of the column of air PLUS the force of the lake water above, divided by the area that the force is acting upon. Therefore, the pressure must be greater at the bottom of the lake.

∙ 12y agoPressure is the force exerted by a mass acting on a surface. It can be expressed as say grams per square centimetre or pounds per square inch. Water has mass. Now imagine a column of water say a metre square and 1000 metres high a not uncommon depth for an ocean. Imagine the tremendous mass of that column and thus the pressure it would exert on the metre square at the bottom of the column.

Can you make it to the bottom of the ocean?
no ur brain would explode from to much pressure
What part of the water has high pressure?
The deeper the water, the higher the pressure. This is due to how much weight is on the water. At the top of the ocean, the only thing above the water pushing down on it is air. However, at the bottom of the ocean you have not only the air but the entire body of water above it pushing down. This creates a greater pressure at lower depths.
What does the depth of the water determine?
The depth of water in a lake, tank, ocean - or whatever contains it will determine the hydro-static pressure at the bottom. It will also significantly influence the temperature and amount of light and thus the ecosystem at the bottom of the water.
As someone goes dives deeper in a ocean they have more PSI acting upon them If this ocean was mercury would the same pressure be greater or less?
Pressure in a fluid at a certain depth H is proportional to the density of the fluid. Since Mercury has a much higher density then water it will exert a much larger pressure at the same depth.
How much ocean does Vietnam have?
The whole east coastline is ocean; from top to bottom.
Why do dams need to be thicker on the bottom and thiner at the top?
because the water pressure on the damn is much higher on the bottom of it than the top.
Why are dams made thinner at the bottom?
This is because the pressure in a liquid increases with depth. This means that the pressure at the bottom of the dam is more. Hence it is more liable to break out from the dam as more pressure is exerted on the walls. So, the walls are thicker at the bottom.
How much pressure is on your lungs in outer space?
well lets just say that if went down to the bottom of the ocean you would be crushed but in outer space it would take half the time
What is a bottom current?
bottom current moves very slow.a slow flowing current at the bottom of the ocean means that the ocean is very calm and has no danger to anyone what so ever .Yes it is very much like a flow of water or wind current. In the case of water, it is the water molecules that flow in a pipe. The head or pressure of water is similar to "voltage", the thickness and..
How much light do blobfish get?
they don't get any because they are at the bottom of the ocean
What factors makes it difficult to explore the ocean floor?
No one can go that far down to the ocean because it would be to much pressure. May your head could blow that's how much pressure it would be.
How much blubber is in a manatee?
Well, because then they wouldn't sink to the bottom of the ocean!
