🔍 Key Concepts

• Seasonal ice conditions on the St. Lawrence Seaway • Typical navigation season closing dates for the Seaway • Relationship between late-fall vs. mid-winter conditions and ice thickness

💭 Think About

• Think about when average winter cold is usually at its strongest and ice has had time to build up enough thickness to stop ships. • Compare each option to the usual period when many northern shipping routes close due to ice, not when it just starts to get cold. • Ask yourself: does navigation usually stop right when temperatures first drop below freezing, or after an extended period of sustained cold?

✅ Before You Answer

• Check which month in the choices best represents deep winter rather than early or mid-fall. • Eliminate any answers that fall before the typical end of the Seaway navigation season. • Make sure the option you pick allows enough time for ice to thicken to a point where it can actually halt ship traffic, not just create the first skim of ice.
