How do surface currents occur?
unequal heating
The rising of cold water from deeper layers to replace warmer surface water is called?
Streamlike movements of water that occur at or near the surface are called surface currents. So logically, a deep current are streamlike movements of water that flow very slowly along the ocean floor.
What are stream like movements of water that occur at or near the surface of the ocean?
Surface currents
Why do deep ocean currents occur?
My best guess is that they occur because of warming and cooling of the surface temperature. I am sure there is a pattern of these deep ocean currents to and from the equator and the poles.
How often does upwelling occur?
When cool nutrient rich water is driven to the surface by wind, replacing warmer and nutrient depleted water, this is known as upwelling. This stimulates the synthesis of organic compounds and helps fishing productivity.
What are streamlike movements of water that occur at or near the surface of the ocean called?
currents
What are two hazards that occur because of cold currents in the North Atlantic?
Thick fogs can occur and they can carry icebergs with them creating hazards for ships
When do surface currents occur?

How does upwelling occur?
Upwelling is a process by which cold water is brought up from the depths of the ocean.
What causes water currents?
Surface ocean currents are mainly wind-driven and occur in all of the world's oceans. Examples of large surface currents that move across vast expanses of ocean are the Gulf Stream, the North Atlantic Current, the California Current, the Atlantic South Equatorial Current, and the Westwind Drift. Associated with surface currents are counter-surface and underlying currents. Surface ocean currents are deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere due to the Coriolis effect. The Coriolis effect holds that because the Earth is spinning, surface waters move in a clockwise direction in the Northern Hemisphere and in a counterclockwise direction in the Southern Hemisphere. The currents eventually come into contact with the continents which deflect them, creating giant oceanic current circles known as gyres. Vertical and ocean-bottom currents are mainly driven by density differences caused by changes in temperature and salinity. Originating in polar regions, cold, salty waters sink to the ocean bottom and move toward the opposite poles where they again surface. Vertical upwelling currents can also be caused by winds "blowing off" a coastline. The displaced waters are then replaced by underlying bottom waters. Currents are important to marine life as they help to move food and nutrients, making them available for photosynthesis, metabolic requirements and/or consumption.
Why do the surface currents move in different direction of the wind?
This is due to temperature and how water with different temperatures react.
How do surface currents differ from density currents?
The same thing! Deep Currents Occur when the density of the water increases. Density is based on two main things it is the civility is how much salt and other solids are in it and it is also the temperature of the water.The lower the temperature the lower the dense the water becomes. The denser the water the more it was to go down. The less dense the water wants to rise. The temperature is what causes the dense. Deep current:A streamline movement of ocean water far below the surface.
