QuestionAnswer
What do ocean currents do? Influences weather and climate.
What determines the density of water in the ocean? Temperature and salinity determines this
What causes ocean currents? The differences in water density.
What is an ocean conveyer belt? Used to connect 4 of the 5 Earth's ocean's.
What is a major factor in driving warm, surfaces/ sections of water? It is wind

What are the differences between the upper layer and the lower layer of the ocean? The upper layer is warm and salty (exposed to the sun), while the lower layer is cold.
How do layers of the ocean affect global temperatures? The flow of water conducts heat from one part of the globe to another, affecting the global temperature.
What causes the slow mixing of layers? The temperature and density of the water.
What can the mixing of layers do? Causes water to slowly flow through the Atlantic, Indian, Pacific, and Southern Oceans. (Ocean conveyer belts)
How does the mixing of layers affect the atmosphere and ocean? It affects the amount of carbon dioxide in the ocean and the atmosphere.
