"CURRENTS" EVENTS

1. Explain how currents contribute to the distribution of marine organisms around the planet.

Different kinds of organisms, as we know it, have certain levels of temperature to live. We also know that the currents help distribute and regulate the temperature. By changing the currents we are changing the ways of the organisms that live on water. Birds, for example, have to migrate because the spawn of fishes changes.


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?
As global warming increases, the temperatures of places change. Different weather happens to those places. With these things that will happen, we can concur that the currents will change because currents are in charge of the climates and the temperature changes.

3. Explain how density changes cause currents.
When water becomes denser, it is downwelling, which means that the surface water sinks. Thus the processes called overturn starts.
