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. What is the primary drivers of river currents?Gravity, channel slope, and hydraulic gradient
2. What is the key drivers of ocean currents?Wind stress, density differences (temperature and salinity), and the Coriolis effect

Hydraulic Gradient: The slope of the water table or surface, indicating the force driving groundwater or surface water flow.
Turbulent Flow: A fluid motion characterized by chaotic eddies, swirls, and fluctuations in velocity and pressure.
Gyres: Large systems of rotating ocean currents, driven by wind and the Coriolis effect.
Coriolis Effect: An apparent force that deflects moving objects (like air and water) due to Earth's rotation.
