Why the pressure of the water is so more in the depth of the Ocean? OR Why there is so much high pressure in the Ocean water compared to small water bodies?

If I have 1 m^2 of space and I put 1 N of force on it, it experiences 1 Pa of pressure.
Air pressure at sea level is about 10000 Pa (1 atm = 101325 Pa)
That same air pressure on that 1 m^2 of space means there’s 10 kN of force on it, and that is the weight of all of the air above it (all the way to space)
Water is heavier than air, infact 1 m^3 of water has a mass of 1000 kg (1 metric tonne) that’s 1 kN of weight (using g = 10 m/s^2 for simplicity)
If we take the 1 m^2 and place it a 10 m under water, that’s 10 kN of water on top of it, resulting in another 10 kPa of pressure, or another atmosphere pressing down on that 1 m^2
The deeper you go, the more pressure you get. Smaller bodies of water aren’t usually as deep as the ocean, so we get higher pressures in the ocean.
