What current brings cold water to the ocean surface?
An upwelling is a current in the ocean that brings deep, cold water to the ocean surface.
What brings electeic current to your home?
deep, cold water to the ocean surface
How does the sun provide energy for surface ocean currents?
The sun heats the water, causing cold / hot circulation, and evaporation. It also heats the air, causing wind, which also moves currents.
Fish are abundant in areas where the ocean is upwelling because it -?
Fish are abundant in areas where the ocean is upwelling because the upwelling brings nutrient-rich water to the surface, which supports the growth of phytoplankton. Phytoplankton is the base of the marine food chain, providing food for small fish which in turn attract larger fish and predators. This creates a productive and diverse ecosystem where fish thrive.
How does atmospheric forcing impact the dynamics of ocean circulation?
Atmospheric forcing, such as wind and temperature changes, can affect ocean circulation by influencing the movement of surface waters and the formation of ocean currents. These forces can drive the mixing of water masses, impact the distribution of heat and nutrients, and play a role in shaping the overall circulation patterns of the ocean.
What is deep water formation?
Deep water formation is the process by which surface waters in the ocean cool and become denser, sinking to the depths of the ocean. This sinking of dense water drives the global thermohaline circulation, which plays a key role in distributing heat and nutrients around the world's oceans. Deep water formation is crucial for ocean circulation and climate regulation.
Describe the two steps of upwelling?
Upwelling occurs when wind pushes surface ocean water away from the coastline, causing deeper, colder, nutrient-rich water to rise and replace it. This brings nutrients to the surface, fueling the growth of phytoplankton and supporting a productive marine ecosystem.
How does water sink to the bottom of the ocean and then rise to the surface again?
Water sinks to the bottom of the ocean due to its density, which is affected by temperature and salinity. Cold and salty water is denser and sinks, while warm and less salty water rises. This movement is known as ocean circulation, where water moves in a continuous cycle from the surface to the depths and back again.
What brings energy to ocean water?
tides
What is the cause of surface currents?
The circulation of cold and warm water between the poles and the equator, and the rotation of the earth, cause ocean currents to flow.
What is the driving force of deep-ocean circulation?
The driving force of deep-ocean circulation is primarily the sinking of cold, dense water at high latitudes due to its higher density. This process is known as thermohaline circulation, where temperature and salinity differences create variations in water density, causing water masses to sink and drive the global ocean circulation.
What part does upwelling play in the global circulation of ocean water?
Upwelling is a process where deep, cold, nutrient-rich water rises to the surface, bringing essential nutrients to the surface waters that support marine ecosystems. This process is crucial for the productivity of marine life and can lead to cooler surface temperatures in coastal regions. Upwelling is driven by factors such as wind patterns and the Earth's rotation, which play a significant role in the global circulation of ocean water.
