Glaciers Are the Earth's Massive Water Reservoirs
A significant share of the Earth's fresh water is stored in the form of glaciers and ice sheets. As climate change accelerates their melting, rising sea levels and shrinking freshwater resources have become concerns of global importance.
Frequently Asked Questions
Are a glacier and an iceberg the same thing?
No β a glacier is a massive body of ice flowing over land, while an iceberg is a piece that has broken off the end of a glacier and floats on the ocean.
