~Currents~

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

~ The ocean currents control the water temperature as it is circulated continually throughout the oceans. Currents have an effect to the distribution of marine organisms around the planet.

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?

~ It is very possible to experience another ice-age due to global warming.

3. Explain how density changes cause currents.
Use google image to find a world map. Copy and paste into paint and use the drawing tools to create the currents and label them.

~ The water will become more dense when the water changes its temperature. Therefore, the colder water will ascend to the surface as this movement helps cause currents.
