Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. How deep is Mixed layer?Ranges from meters to hundreds of meters, influenced by weather and season
2. What is the oceanographic zone?The uppermost layer of the ocean characterized by turbulent mixing
3. What is the primary forcing mechanisms?Wind stress, wave action, and buoyancy fluxes
4. What is the ocean's mixed layer?It is the top part of the ocean where wind and waves stir the water, making the temperature, salt, and density the same all the way down a little bit.
5. Why does wind stir the ocean's surface?Wind pushes on the water, creating little whirlpools and eddies that mix the surface water with the water below.

Turbulent Mixing: The chaotic movement of water that homogenizes its properties.
Seasonal Thermocline: A sharp vertical temperature gradient that forms in summer.
Euphotc Zone: The upper layer of a body of water that receives sufficient sunlight for photosynthesis.
Buoyancy Flux: The transfer of heat or salt across the ocean surface affecting water density.
