🔍 Key Concepts

• Seiche as used in Great Lakes and harbor forecasting terminology • Difference between a current, a water level fluctuation, and a storm system • How water in an enclosed or semi-enclosed basin behaves after a strong disturbance (like wind or pressure) stops

💭 Think About

• Ask yourself: Is a seiche describing the cause (like a storm or seasonal current) or the behavior of the water after it’s been disturbed? • Which option best matches a standing-wave or bathtub‑sloshing type motion in a lake or harbor? • Look for the answer that focuses on oscillation of water level in a basin, not on long‑term seasonal patterns or specific storm directions.

✅ Before You Answer

• Eliminate any choice that talks mainly about storm systems or weather origins rather than water motion itself. • Check whether the option describes a temporary oscillation/standing wave instead of a persistent current or long‑term high/low water condition. • Verify that the definition applies to enclosed or semi‑enclosed bodies of water (like lakes, bays, or harbors), not just general ocean tides.
