                  - Closing  

Lesson Goals 

After today's lesson you'll be able to...

              - explain the difference in the weight of water

              - explaing why there are warme and cold ocean currents

              - explain what we notice of the gulfstream

1. true
2. false

Ocean pumps 

Warm water

form the.... 

Flows north to the... 

Why?

Why not the Southpole.. 

What happens at the Nortpole?

Why is the salinity underneath the Sea Ice of the North pole high?

Saline water underneath the ice 

Salt water cools down 

The water freezes 

The salt doesn't 

The water get's more and more salt thus heavier 

What are the effects in the Netherlands of the warm oceanic current?
