What is the main energy source for ocean currents that move large volumes of water around the planet? Earth’s core.
What drives the deep vertical movement of ocean water?
What drives the vertical movement of ocean water? … The whole ocean is involved in slow thermohaline circulation, a process responsible for the large-scale vertical movement of ocean water and the circulation of the global ocean as a whole.
What is the main force that drives deep ocean currents quizlet?
It is driven by heat and salinity of the sea water which is where the term thermohaline comes from. Temperature and salinity make up the density of the water. There are different densities that occur in the ocean waters of the world and this is what causes the currents.
What forces are responsible for the movement of ocean water in currents quizlet?
Temperature and salinity both influence the movement of water in deep-ocean currents.
What are the 3 types of ocean currents?
Oceanic currents are driven by three main factors:
- The rise and fall of the tides. Tides create a current in the oceans, which are strongest near the shore, and in bays and estuaries along the coast. …
- Wind. Winds drive currents that are at or near the ocean’s surface. …
- Thermohaline circulation.
Which condition would cause an increase in the salinity of ocean water?
Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean. However these “salinity raising” factors are continually counterbalanced by processes that decrease salinity such as the continuous input of fresh water from rivers, precipitation of rain and snow, and melting of ice.
What forces are responsible for the movement of ocean water in currents?
Ocean currents are the continuous, predictable, directional movement of seawater driven by gravity, wind (Coriolis Effect), and water density.
Which way do ocean gyres typically move?
The North Atlantic Ocean Gyre always flows in a steady, clockwise path around the North Atlantic Ocean. Some gyres experience seasonal variation, however. The Indian Ocean Gyre is a complex system of many currents extending from the eastern coast of Africa to the western coast of Australia.
What are deep ocean currents caused by?
In contrast to wind-driven surface currents, deep-ocean currents are caused by differences in water density. The process that creates deep currents is called thermohaline circulation—“thermo” referring to temperature and “haline” to saltiness.
How do ocean currents affect climate provide at least three examples?
Provide at least three examples. Ocean currents influence climate because the currents are major redistributors of heat and energy throughout the globe. Warm currents such as the Gulf Stream cause regions that would normally be cold to be warmer. … Cold currents cause the air above them to be cooler.
What is driving force for a deep-ocean current?
Winds drive ocean currents in the upper 100 meters of the ocean’s surface. However, ocean currents also flow thousands of meters below the surface. These deep–ocean currents are driven by differences in the water’s density, which is controlled by temperature (thermo) and salinity (haline).
What is the driving force behind winds and ocean currents?
The main drivers of ocean currents are as follows: 1. The Coriolis Force. The rotation of the earth causes two main inertial forces: the centrifugal force pointing straight up (which is mostly swamped out by gravity), and the Coriolis force which points perpendicular to an object’s motion.
