well, keep in mind that the sea is another world,
there is a very rare animal/plant called the spectrolium hiter
the spectrolium hiter is a amimal which is about 1m long nd when it has died it decomposes in to a plant
it is a very animal and lives in the density below the surface of the sea
they are very dangerous and are known to have killed sharks.
Density always increases as altitude decreases. So the air density below sea level will be greater than the air density at sea level.
As the depth increases, the density increases also.
About 70%
There are many land locations on Earth that are below sea level. The lowest point is the Dead Sea, the surface of which is about 420 m (1,378 ft) below sea level.
The lowest point relative to "sea level" of Mars (officially measured relative to the "reference ellipsoid" for Mars) is Hellas Planitia. This huge impact crater is about 7km (4.5 miles) below the reference ellipsoid (below "sea level"). By comparison, the Challenger Depth in the Marianas Trench is the lowest point on the Earth's surface and is about 11km below sea level. (The lowest land elevation is the Dead Sea -- 422m below sea level. Water likes to fill in hole on the earth's surface!)
The pressure at 100 meters below the surface of sea water with a density of 1150kg is 145.96 psi.
Density always increases as altitude decreases. So the air density below sea level will be greater than the air density at sea level.
The waves on the sea's surface are tranverse, the waves below the surface are longditudinal.
The surface is 1300 feet below sea level
The greater the depth the greater the pressure.
Pressure increases the deeper you sink beneath the surface of the sea. So 20 metres below the surface has more pressure than 10 metres above the surface.
Rivers' surface located in deep valleys can be below of the ocean surface. Furthermore, there are underground rivers which certainly are below sea level, depending on how deep such rivers are placed below-ground.
Yes, as changes in salinty affects the density of sea water, another of putting it would be that a Halocline is simply a region below the surface of a body of water where there is a significant increase or decrease in density.
Otters can change their density to either float on the surface of the water, or sink. Therefore, their density can vary.
It is a submarine.
They are chunks of floating ice drifting away from polar regions. The density of ice is just a little less than the density of sea water, so most of the volume of an iceberg is below the surface, and so a small-looking iceberg can have a huge volume of ice below the surface. The Titanic ran into an iceberg and was holed below its waterline so the water rushed in and the ship sank.
No, its surface and shores are 423 metres below sea level.
