Depth and temperature.
cold ocean water is more dense than warm water
The water from a melted glacier is less dense than the water of the seas.
The warm air is moist due to water evaporating from the land/ocean. It is low pressure because warm air is less dense, and rises, creating an area of low pressure.
It becomes more dense as it cools, until its density is greater than the asthenosphere below it.
Ocean to ocean convergent plate boundaries do not have a chain of composite cone volcanoes. The ocean plate that is more dense will sink beneath the other ocean plate.
There are two main factors that make ocean water more or less dense the temperature of the water and the salinityof the water.
The ocean is most dense towards the bottom of the sea. As the water in the ocean gets colder it gets more dense.
the most dense part5 of the ocean is my ballbag
At the surface of the ocean in the warmest area of the ocean.
the atlantic ocean
more dense
In an oil spill in the ocean, the oil rises to the top because it is less dense than water, creating an oil slick on the surface of the ocean. A Styrofoam cup is less dense than a ceramic cup, so the Styrofoam cup will float in water and the ceramic cup will sink.
open ocean zone
An increase in ocean salinity can increase density creating a convection current.
El Nino waters are less dense because the waters are warmer and warm water is less dense than cool water. Also, it constantly rains over the ocean during the El Nino, and rain water is less dense than ocean water.
The ocean is stratified with denser layers below less dense layers.
I think that it causes a deep ocean current.....
