The water at the surface of the ocean is generally warmer and more oxygen-rich due to exposure to sunlight and atmospheric interaction, supporting a diverse range of marine life. In contrast, water hundreds of meters below is colder, denser, and often has higher pressure, with reduced light penetration and lower oxygen levels. This deeper water can also contain different nutrient profiles and is less influenced by surface weather conditions. Overall, these differences create distinct ecological zones within the ocean.
surface
A minuscule region comprised of the surface and a few hundreds of meters above and below it.
add 1 atm (atmosphere) for every 10 meters 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.
Less pressure because ocean water is salty and therefore denser.
Inland :Asia.(The surface of the Dead Sea on the border between Israel and Jordan is 424 meters below sea level and the deepest depth is 377 meters below that).At sea:Pacific Ocean (might be called part of the Asian continent but it really isn't)The challenger Deep of the Mariana Trench is 10,971 meters below the surface
The pressure at 100 meters below the surface of sea water with a density of 1150kg is 145.96 psi.
2 meters below the surface
The diving bell, located 275 meters below sea level, is closer to the sea compared to the helicopter flying at 302 meters above sea level. While the helicopter is above sea level, the diving bell is submerged underwater, making its position closer to the surface of the sea. Therefore, the diving bell is the closer of the two to the sea.
The lowest elevation on Earth's surface is the shoreline of the Dead Sea, which is about 1,400 feet (430 meters) below sea level.
Gold can be found at varying depths in the Earth's crust, typically ranging from a few meters to a few kilometers deep. Commercially viable gold deposits are usually found at depths of hundreds of meters to a few kilometers below the surface, where geological conditions have concentrated the gold into mineable ore bodies.
