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 Wind generated current?Approximately 400 meters, influenced by viscosity and friction
2. What is the driving force?Momentum transfer via wind stress (friction)
3. What is the key oceanic processes?Initiates Ekman transport, leading to upwelling, downwelling, and geostrophic flows
4. What is a wind-generated current?A wind-generated current is a river of water in the ocean that is pushed by wind. The wind’s friction on the surface makes the water move, and the motion can travel deep into the ocean.
5. How does wind make ocean water move?The wind pushes on the water’s surface, giving it momentum. The faster and longer the wind blows, and the farther it travels over the water, the stronger the current becomes.

Wind Stress: The frictional force exerted by wind on the water surface, initiating motion.
Ekman Transport: The net movement of the upper layer of water at approximately 90 degrees to the wind direction.
Geostrophic Flow: A state where the Coriolis force and pressure gradient force are balanced, resulting in flow parallel to isobars.
