Currents

1. Explain how currents contribute to the distribution of marine organisms around the planet.
   Currents disturb marine organism because of the continuous movement of the water and by currents that regulate the temperatures of the land and water.
   
   

2. The primary factor influencing ocean currents is temperature regulation. What might happen to the ocean currents (and has happened in the past) as global warming increases?
   With the change of the currents temperature, its activities and movements would change as well.

   
   

3. Explain how density changes cause currents.
   When the water on top becomes denser it sinks to the bottom allowing cooler water to rise to the top, thus creating a lot of underwater movement that we call a current.
