How often do currents change direction in Lake Ontario?

• A. Hourly
• B. Daily
• C. Weekly
• D. Seasonally

Answer: (B)

Currents in Lake Ontario typically change direction on a daily basis due to a combination of factors such as wind patterns, atmospheric pressure, and thermal stratification. Daily changes are particularly influenced by the wind, which can cause surface currents to shift throughout the day, depending on the prevailing weather conditions. In contrast, hourly changes may occur in more localized areas or during specific weather events, but they are not the norm for the lake as a whole. Weekly changes would not accurately reflect the dynamic nature of currents influenced by daily climatic and environmental variations. Seasonal changes do affect overall current patterns and water temperature but are less frequent and do not capture the more immediate fluctuations that happen daily. Understanding this daily cycle is crucial for navigation and fishing activities on Lake Ontario, as it helps mariners anticipate changes in current that could impact their routes and fishing strategies.
