Density: a variety of factors affect water density, more dense water sinks, setting up convection currents

Density can be affected by the temperature of the water

cold

warm

Surface Currents- the water at the ocean surface 

The Surface Current is effected by the way the wind blows.

95. Upwelling

Upwelling- nutrient rich water comes to the surface 

Upwelling is a replacement for warmer water.

nutrient depleted 

97. Corolois Effect

Corolois Effect- the apparent deeflection of rotating motion 

Surface Currents are directly affected by the Corolois Effect.

Deep Ocean Current- Currents that are directly effected by temperature and density 

Deep ocean Currents are a type of current from density and temperature.

Water Cycle- the process of how the Earth naturally replenishes water 

The Water Cycle is a very important cycle that happens in your everyday life.

evaporation 

Ground Water- water beneath the Earths surface 

We get ground water through processes like precipitation. 

precipitation 

transpiration 

Surface Water- water on the surface of the earth 

Surface water can be seen everywhere.  

rivers 

lakes 

water table- a saturated lauer of underground water 

Peremeable- water can get through it 

Impereable- water can not get through it 

Confined Aquifer- an underground aquafer 

Unconfined Aquifer- an aquifer near the ground surface 

Pumped well- a structure used to obtain water from under the surface 

Artisan well- an aquifer containing ground water is put infer positive pressure. 

Zone of Saturation- an area underground where pore spaces can be filled witn water 

zone of aeration- an area underground where the pore spaces can be filled with air 

cone of depression- where the water is coming from when using a well

well- a cylinder shaped construction used to obtain underground water 

Wells are not really relevant today.
