Glacier
A glacier is a large, persistent body of ice that forms over centuries from compacted snow and flows slowly under its own gravity, shaping landscapes through erosion and deposition. In today's context, glaciers serve as vital barometers of climate change, with their rapid melting contributing to rising sea levels and highlighting the urgency of environmental conservation.
Did you know?
The Hubbard Glacier in Alaska advances at a rate of up to 20 feet per day during surges, making it one of the fastest-moving glaciers, and it once dammed a river in 1986, creating a massive lake that burst and flooded areas downstream. This event underscores how glaciers can dramatically alter landscapes in mere days, despite their typically slow pace.
