Vertical Circulation
Hello world, today we were given sheets and answered questions. Here are those questions. I'll see you later. Peace!
Density in the ocean is primarily determined by: temperature and salinity.
- Colder water has a higher density than warm water. - Saltier water has a higher density than fresh water. Deep currents in the ocean are cause by: changes in ocean density Water that sinks: 1) It is dense. 2) It is found in a few small places near the poles. 3) It moves quickly. Water that rises: 1) Rises over the whole ocean. 2) Rises very slowly. 3) Gradually becomes less dense. * It takes about 1,000 for water to rise from the bottom of the ocean to the surface. Deep water currents are important because: 1) Transport heat around the globe. 2) Affects our climate. 3) Brings nutrients from the bottom of the ocean to the surface. * If water took longer to rise, the surface could be warmer. Vertical Layering: 1) Where the water has come from. 2) The ocean currents. 3) How the ocean water is mixed. |
Both Pictures show a slice through the Atlantic Ocean. The top picture is temperature and the bottom is salinity.
1. At 50 degrees south, estimate the temperature at the surface and the bottom.
> Surface temperature: About 1 degrees Celsius
> Bottom temperature: About 0 degrees Celsius
2. At 10 degrees south, estimate the temperature at the surface and the bottom.
> Surface temperature: About 25 degrees Celsius
> Bottom temperature: About 0 degrees Celsius
3. Is water more likely to sink near 10 degrees Celsius south or near 59 degrees Celsius south? Why?
> It is more likely to sink at 50 degrees Celsius south, because there is a lot of salinity in that area.
4. Looking at the picture of salinity, describe the different vertical layers you see.
> The bottom layers stay neutral, while at the top the water is moving and sinking.
5. Show the arrows you drew to show that the water is moving horizontally or vertically in the salinity picture.

I see that you are done with this page. I'll see you later. Peace!
