🔍 Key Concepts

• Latitude and climate differences among the Great Lakes • Effect of lake depth and volume on winter freezing and shore ice • Prevailing winter wind and temperature patterns over the upper Great Lakes

💭 Think About

• Which Great Lake is generally the coldest on average and located farthest north and west? • How do depth and total water volume affect how quickly a lake cools and forms ice near shore compared to the center? • Which lake is known for having very cold water temperatures and extensive winter ice coverage in many seasons?

✅ Before You Answer

• Compare the average winter temperatures and ice coverage data historically reported for each Great Lake • Think about which lake often still has lingering ice and very cold water well into late spring • Consider how exposure to Arctic air masses differs among the four options listed
