how does density affect ocean currents

Density in the atmosphere is also important in the formation of clouds and precipitation. The technical definition of density is mass per unit volume. … In the atmosphere, gas that is less dense has a lower concentration of molecules per volume than a denser gas and will tend to rise compared to the air around it.

How do density differences cause movement?

Explanation: A pressure gradient (change in air pressure over distance) is what causes the air to move as the atmosphere tries to balance itself. Air will move from an area of high pressure to an area of low pressure. Density is inversely proportional to pressure (the lower the density the higher the pressure).

How does the ocean’s density stratification limit the vertical movement of seawater?

A body of water with characteristic temperature, salinity, and density. How does the oceans density stratification limit the vertical movement of seawater? Only waters with similar densities can mix.

Where is ocean water the densest?

Such areas as the Weddell Sea in Antarctica produce the densest water of the oceans. This water, known as Antarctic Bottom Water, sinks to the deepest depths of the oceans.

How does salinity affect ocean circulation?

Since warmer water thus can hold more salt and other molecules than cold water; it can have a higher salinity. To relate this to ocean currents, the higher the salinity of ocean water, the more dense it becomes. When the salinity is high enough, the water will sink, starting a convection current.

Is where density increases rapidly with depth in the oceans water column?

pycnocline
As depth increases, there is a region of rapidly increasing density with increasing depth, which is called the pycnocline . The pycnocline coincides with the thermocline , as it is the sudden decrease in temperature that leads to the increase in density.

Where and how is the densest water in all the oceans formed?

The densest ocean water is formed in two primary locations near the poles, where the water is very cold and highly saline as a result of ice formation. The densest deep water mass is formed in the Weddell Sea of Antarctica, and becomes the Antarctic Bottom Water (AABW).

What three factors affect ocean surface currents?

Surface currents are controlled by three factors: global winds, the Coriolis effect, and continental deflections. surface create surface currents in the ocean.

What are four factors that affect ocean currents?

There are four factors affecting the origin and flow of Ocean Currents i.e. Rotation and gravitational force of the Earth; Oceanic factors (temperature, salinity, density, pressure gradient and melting of ice); atmospheric factors (atmospheric pressure, winds, rainfall, evaporation and insolation); factors that …
