On the Great Lakes, which can cause short-term fluctuations in water levels?

🔍 Key Concepts

• Short-term vs. long-term changes in water level on large inland lakes like the Great Lakes • Effects of wind and atmospheric pressure on water piling up or dropping suddenly • Definition of seiche compared to normal waves or tides

💭 Think About

• Which choice describes something that can make the water level rise and fall noticeably within minutes to hours rather than over weeks or months? • Think about which options involve an oscillation or sloshing motion of the whole lake rather than just a local surface effect. • Which options would more likely cause gradual, seasonal changes instead of rapid, short‑term fluctuations?

✅ Before You Answer

• Identify which options are clearly long-term climate/seasonal factors rather than short-term events. • Ask yourself which phenomenon can cause water to rise and fall repeatedly along a shoreline in a relatively short period of time. • Eliminate any answer that suggests conditions are steady or calm, since those generally do NOT create rapid level fluctuations.
