= Convection Currents =

Convection currents are caused by the different water temperatures. The change of water temperature changes the water's density. The colder water is more dense and the warm water is less dense creating a current. = What are gyres? = = = Gyres are a large circular pattern of ocean currents. = = = How Are Currents Created? = = = media type="youtube" key="Hu_Ga0JYFNg" height="349" width="425" align="center"



The cold water from the poles sink to the equator having the warmer water moving to where the cold water use to be.

The blue dye represents cold water and the red dye represents warm water. The cold water is more dense making it sink to the bottom, while the warm water is less dense putting it on top. The two temperatures mix and starts to form a current.

The Labrador currents meets the Grand Banks pushing the nutrient-rich waters up increasing the activity of plant and animals.

= Glossary =

Current - Water movement created by the change on water temperature in an ocean or lake.

Convection Current - A current that was created from the change of water temperature.

Gyres - A large circular pattern of ocean currents. By Jordan Toews And Tyler Chong
