Currents change direction due to factors such as wind patterns, temperature variations, tides, and the rotation of the Earth, known as the Coriolis effect. These factors can influence the movement of water masses, leading to shifts in current direction.
circulating winds
In the northern hemisphere, currents are influenced by the Coriolis effect, which causes moving air or water to be deflected to the right. This is due to the rotation of the Earth, which causes an apparent force to the right of the direction of motion in the northern hemisphere. As a result, currents tend to flow in a clockwise direction in the northern hemisphere.
An external force is a force that causes a change in an object's motion by pushing or pulling it in a certain direction. This force can accelerate, decelerate, or change the direction of the object's movement.
If a change in the body causes more change in the same direction, the system is called positive feedback. This feedback loop amplifies the initial change and pushes the system further away from its original state.
Surface currents are primarily caused by the wind. As wind blows across the surface of the ocean, it creates friction and imparts energy to the water, causing it to move in the same direction as the wind. Other factors, such as the Coriolis effect and differences in water density, can also influence the direction and strength of surface currents.
You can change the direction of a compass needle by creating a magnetic field with a current-carrying wire. By passing a current through the wire and holding it near the compass needle, you can influence the direction in which the needle points. The strength and orientation of the magnetic field generated by the wire can cause the compass needle to deflect from its original direction.
Alternating Current
An oceans currents will change direction when they hit a continent.
Continents can affect surface currents by causing them to deflect due to the Coriolis effect. This effect is caused by Earth's rotation and causes surface currents to change direction as they flow around land masses. The shape and location of continents can also influence the direction and strength of surface currents by creating barriers or channels for the flow of ocean water.

We know that ocean currents change direction when meeting a continent. The water must flow around the land, so it has to change direction to do that.
A surface current is a current caused by wind direction
In the northern hemisphere, currents are influenced by the Coriolis effect, which causes moving air or water to be deflected to the right. This is due to the rotation of the Earth, which causes an apparent force to the right of the direction of motion in the northern hemisphere. As a result, currents tend to flow in a clockwise direction in the northern hemisphere.
The Coriolis effect causes currents in the northern hemisphere to turn to the right.
Convection currents move in upward direction
rapid tempature change is the main characteristic that effects deep ocean currents.
