1. Explain how currents contribute to the distribution of marine organisms around the planet. Currents have an effect to the distribution of marine organisms around the planet. It controls the water temperature as it continually circulates throughout the sea/ocean.
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? Another experience of ice-age may possibly occur as global warming increases.
3. Explain how density changes cause currents. As the water changes its temperature, it becomes more densed. Therefore, the colder water ascends to the surface, causing the currents.
