Which consequence results when glacial till obstructs drainage pathways?

💡 Explanation

Kettle lakes form because glacial retreat deposits till, which when blocking drainage routes causes meltwater to pond and creates depressions that subsequently form lakes. Therefore, kettle lakes are prevalent, rather than increased chemical weathering, which requires different geochemical conditions.
