Ocean Currents
by Nicole Ngy
1. Composition of Seawater
1.1. Sources of sea salts: they come from chemical weathering from rocks
1.2. processes affecting salinity: wherever water is stored it ranges from 33% to 38%
2. Deep Ocean Circulation
2.1. water evaporates with salt
2.2. conveyor belt: the image of a warm surface current under a cold surface current
2.3. Density currents: movement in water that make different water mass
3. Diversity of Ocean Life
3.1. water depth:
3.1.1. Goal 1
3.1.2. Goal 2
3.2. depending where the zone of the ocean is different sea creatures and plants live/grow there
3.2.1. Session Rule 1
3.2.2. Session Rule 2
3.2.3. Session Rule 2
3.3. distance from shore:
3.4. shore life is hard because of the constant wave crashing, farther the less movement
3.5. availability of sunlight:
3.6. when the sunlight hits the ocean it goes to many of the oceans plants providing food for some, and the food chain continues.
4. ocean circulation
4.1. surface circulation: how water moves on the surface
4.2. gyres: the wind movements
5. upwellings
5.1. when cold water from layers underneath come up to warm water
5.1.1. Sub Idea 1
5.1.2. Sub Idea 2
