Ocean Currents
What are wind driven currents called?
Surface currents.
What percent of deaths are related to Rip Currents?
80 percent.
What does the Coriolis Effect cause fluids to do?
It cause them to cure left or right depending on what hemisphere it's in.
What does upwelling bring to the ocean's surface?
Cold, nutrient, rich water from deep in the ocean.
How long does it take The Great ocean Conveyor belt to complete a cycle?
About 1000 years.
What influence the formation and direction Ocean currents move?
Prevailing winds.
How many deaths are Rp Currents responsible for each year in the US?
About 150 deaths.
What affects the flow and speed of currents?
The shapes of continents and other land masses.
What happens to deeper colder water when upwelling occurs?
It rises.
Where does deep water return to the surface through the process of upwelling?
The Indian and Specific Oceans.
How fast do ocean currents move?
100 km/day.
If you get caught in a Rip current which way do you swim?
Parallel to the shore.
What do currents form?
Small or large loops.
Where does upwelling often occur?
It often occurs along coastlines.
Where does high salinity water cool and sink in this model?
The North Atlantic.
How far below the surface do ocean currents extend?
400 m.
What causes Rip Currents?
Pressure buildup from uneven buildup of water from waves.
What causes the Coriolis Effect?
The Earth's rotation.
When does upwelling occur?
It occurs when the wind blows across the ocean's surface and pushes water away from an area.
What does it affect and how does it affect it?
The weather and climate by circulating thermal energy around Earth.
What is an Ocean Current?
A large volume of water flowing in a certain direction.
What is a Rip Current?
A narrow powerful surface current that flows away from the shore.
What is the Coriolis Effect?
It is the movement of wind and water to the right or left.
What is upwelling?
The vertical movement of water towards the oceans surface.
The Great Ocean Conveyor Belt is a name for what?
A model of the large system of ocean currents.
