Glacier
A mass of ice on land formed from accumulated snow, flowing downslope and contributing to sea level rise when melted.
Real World
Switzerland's Rhône Glacier has retreated over 1,400 metres since 1856, and locals now cover sections with white blankets each summer to slow melting and protect tourism revenue.
Exam Focus
Use the terms 'accumulation zone' and 'ablation zone' precisely — examiners reward correct glaciological terminology.
