Salinity differences can create a current through a process called thermohaline circulation. This occurs when variations in water density due to differences in temperature and salinity cause water to move in response to gravity. In regions where water becomes denser due to higher salinity, it sinks and creates a flow towards areas of lower salinity, resulting in a current.

What controls the flow of current with an electric field?
The flow of current in a material is controlled by its conductivity, which is influenced by the presence of an electric field. When an electric field is applied, it can cause charged particles in the material to move, resulting in the flow of current. The conductivity of the material determines how easily current can flow in response to the electric field.
Once a current is set in motion what changes its course?
Coriolis effect
A wire cannot cause a magnetic field if what?
A wire cannot cause a magnetic field if there is no current flowing through it. Magnetic fields are generated by the flow of electric current in a conductor.
What is the cause of a magnetic field about a current-carrying wire?
A magnetic field is created around a current-carrying wire due to the flow of electric charge. The moving electrons in the wire generate a magnetic field perpendicular to the direction of the current flow, following the right-hand rule. This phenomenon is described by Ampère's law.
What does negative current mean and how does it affect electrical circuits?
Negative current refers to the flow of electrons in the opposite direction of conventional current flow. In electrical circuits, negative current can cause components to operate in reverse or malfunction, potentially leading to circuit failure or damage.
What is applied to a conductor to cause current flow?
voltage is applied to a conductor to cause a current flow
How does voltage cause current to do work?
A voltage will cause electrons or other charge carriers to flow (if there is a path through which they can flow). In other words, it will cause a current.
Can Magnetism cause an electric current to flow in a conductor?
Yes, a MOVING magnetic field will cause electric current to flow in a conductor. Conversely an electric current flowing in a conductor will cause a magnetic field.
In which ocean do equatorial currents flow?
The warm, low salinity waters from Pacific are transported into Indian Ocean's South Equatorial Current.
Does lightning cause the air to break down and cause current flow?
A: Lightning is not the cause but the result when clouds or dust particle containing energy discharges its energy. Current will flow from positive to negative potentials
An increase in ocean salinity can increase what creating a current?
An increase in ocean salinity can increase density creating a convection current.
How current are made?
You cause the current to flow through an electronic device that allows current to flow in one directionbut not in the other direction. Such a device is called a "diode" or a "rectifier".
Which has greater salinity a deep current or surface current?
wat
When does a deep current form?
A deep current forms when water masses sink and flow horizontally along the ocean floor due to differences in temperature and salinity. This creates a slow-moving, deep-sea current that can transport large amounts of water and nutrients over long distances in the ocean.
What controls the flow of current with an electric field?
The flow of current in a material is controlled by its conductivity, which is influenced by the presence of an electric field. When an electric field is applied, it can cause charged particles in the material to move, resulting in the flow of current. The conductivity of the material determines how easily current can flow in response to the electric field.
How do we usually think of voltage as the cause and currents the effect?
You apply a voltage across a load and the result is that a current flows through the load. So you must have the voltage present, the cause, before current flow, the effect. Think of voltage as pressure and current as flow.
How does voltage cause current to work?
Voltage provides the "pressure" to push current "flow" through the circuit resistance.
