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. The currents control the water temperature as it continually circulates throughout the sea or 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?
*As global warming increases, it is very possible to experience another ice-age.

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.
*When water changes its temperature, it becomes more dense. Therefore, the colder water will ascend to the surface. This movement helps cause the currents.
