It's buoyancy since the air in the bottom of the ship keeps it afloat. The air is lighter and less dense, so it does not sink into the water. The amount of air must be adequate to the boat's size. Bigger boats need more buoyancy.

because sicience says it has to!!!!!! DUH!!!!! That second word should be "science", anyway, the better answer is that as depth increases, it gets colder. As the water gets colder, it becomes more dense. Now, do not confuse density with pressure. Density is, for all intents and purposes, a material, solid, liquid or gas, becoming more compact. Pressure can be a function of this, but it is also the weight of the mass acting on itself, and what ever it is acting against, such as the ocean bottom, or anything in it, such as a diver, or a submarine.
stingrays move with their wings in the bottom of the ocean where it is sandy and dark.
There are two main factors that make ocean water more or less dense the temperature of the water and the salinityof the water.
The question is incomplete. No options (for which of the following) are given to answer the question.
Ocean lithosphere is higher density so it sinks to the bottom.
it has the highest density. it has the fewest plants. apex (:
density helps you dertermine because substances is about something that have alot for example the ocean and density means the same thing nut in different words i hope you indertend
The factors that can modify the currents are direction and shape of coastlines, bottom reliefs of the ocean basins, seasonal variations and rotation of the earth. Ocean circulation is driven by winds and by differences in water density
The bottom of the ocean doesn't freeze.
what is wrong with this sentence "the bottom of the ocean is different from land masses because the ocean bottom is perfectly flat."
How scientists map the bottom of the ocean
The bottom of the ocean that is slimy is called a biogenous bottom. Some scientists refer to this kind of ocean bottom as an ooze. They are the result of a dominance of calcium shells and siliceous shell pieces which dissolve at the bottom of the ocean.
From its Wikipedia page: "Being the densest water mass of the World Ocean, AABW is found to occupy the depth range below 4000 m of all ocean basins that have a connection to the Southern Ocean at that level." The Southern Ocean freezes at about a depth of eight to 12 feet during the winter months, which is not deep enough to freeze the bottom water.
Ocean Bottom Nightmare was created in 2007.
The density of surface seawater ranges from about 1.020 to 1.029 g·cm-3, depending on the temperature and salinityThe average density of seawater at the surface of the ocean is 1.025 g/ml; seawater is denser than freshwater (which reaches a maximum density of 1.000 g/ml at a temperature of 4°C) because of the added mass of the salts.
Greater density
