Transcript of Copy of Ocean Currents Graphic Organizer
This is the apparent curving of global winds, ocean currents, and everything else that moves freely across the surface of the Earth. Ocean Currents Surface Currents affect Deep Currents They move warm water away so cool water from deep currents can come up. Convection Currents created by Deep and Surface Currents help distribute heat energy throughout oceans. Without convection currents, ocean waters would be extremely different temperatures in different places. Movements of ocean water far below the surface. by: Allyson, Amelita, Darlene, Esther -Streamlike movements of water in oceans. Ocean currents are a continuous, directed movement of ocean water generated by the forces acting upon it.
Sometimes observed as a vertical or horizontal movement of both surface and deep water throughout the world's oceans. They normally move in a specific direction and aid the importance of the circulation of Earth's moisture, weather, and water pollution. Deep Currents Currents that occur on or near the surface of the ocean; caused by wind. Together, Surface and Deep Currents create convection cells all over the Earth. Differences in Density are caused by two things; temperature and salinity. Salinity is a measure of the amount of dissolved solids in a liquid. The higher the salinity or lower the temperature, the denser the water and vice versa. Deep Currents Carry cool water back down towards the equator after it is cooled at the poles. What are ocean currents? Where are currents found? Oceanic currents are found all over the globe and vary in size, importance, and strength Coriolis Effect What is the economic importance of currents in an area? Our economy depends on the oceans for fishing and boating industries and ocean transport. If the ocean currents are warm more fish are being found. Ocean currents influence the amount of fish in an area. It takes more energy to change the temperature of the water than land or air. Water warms up and cools off slowly resulting in inland climates to more extreme temperature ranges than coastal climates.
