Main Factors Of Cause Ocean Currents
What Causes Ocean Currents ?
Main Factors Of Cause Ocean Currents - This time we will discuss the Main Factors Of Cause Ocean Currents. What are the main factors causing ocean currents? The current is a process of mass water movement to the equilibrium that will cause the vertical and horizontal displacement of the water mass, while
The Sea is a very large collection of saltwater and is located in a large area and associated with the oceans. Ocean Currents is the process of movement of water masses to the equilibrium vertically and horizontally that occurs in a vast place that occurs throughout the oceans in the world.
2 causes of sea currents
- Internal Factors
Internal factors include differences in sea water density, horizontal pressure gradients and friction of the water layer. - External Factors
External factors include the moon and sun tensile forces that are influenced by the sea floor resistance and the coriolis force, the difference in air pressure, the force of gravity, the tectonic force.
In addition to the wind that is the cause of ocean currents, it turns out these 3 components:
3 Components Causes Of Sea Currents
- Topographic shape of the ocean floor and surrounding islands
- Coriolis style and Ekman current
- Differences in density and Upweling and sinking
Types Of Currents in Ocean
- Based on the depth
- The current in that occurs at the bottom of a distant water pond and the direction of movement is not influenced by the pattern of wind distribution and will bring the water mass from the poles to the equator.
- Surface Current is Current occurring at several hundred meters from the surface, and moving in a horizontal direction that is influenced by the pattern of wind distribution - Based on cause of occurrence
- Tide current is the current that is affected by the tide
- Ekman currents are currents influenced by wind
- Termohaline current is influenced by density and gravity
- Geostrophic currents are currents influenced by horizontal pressure gradients and coriolis forces
- Wind Driven Current is a current that is influenced by the pattern of wind movement that will occur in the surface layer.
