❄️ Glaciers and Ice Caps
Explore the formation, structure, and global distribution of glaciers and ice caps. Learn how glaciers store freshwater, influence sea levels, and respond to climate change. This quiz examines accumulation and ablation zones, analyzes ice cap distribution in Greenland and Antarctica, and develops skills in interpreting glacier retreat and advance patterns as climate indicators. **What you'll learn:** - How glaciers form and maintain accumulation and ablation zones - The distribution and characteristics of Earth's major ice caps - The relationship between glaciers, freshwater storage, and sea-level change - How climate change affects glacier dynamics and retreat - How to interpret glacier behavior as a climate change indicator
