Question

analysis questions: 1. explain how salinity impacted the movement of water in your model. 2. this investigation was a model simulation. based on what you know about oceans, what were some of the limitations of this model?

Explanation:

1. Salinity affects water movement through osmosis and density - differences. Higher salinity makes water denser, causing it to sink in a water - column, driving circulation patterns. In a model, this could be seen as water moving from areas of lower to higher salinity to equalize concentration gradients.
2. Model limitations for ocean simulations include not accounting for real - world complexity like large - scale ocean currents, tides, and interactions with the sea - floor and atmosphere. Also, the model may not accurately represent the vastness and variability of ocean conditions such as temperature and salinity gradients over large areas.

Answer:

1. Salinity impacts water movement via osmosis and density changes. Higher salinity makes water denser, leading to sinking and circulation to balance concentration gradients.
2. Model limitations: lack of real - world complexity (currents, tides, sea - floor/atmosphere interactions), inability to represent vastness and variability of ocean conditions accurately.
