Front

What is the percentage of readily available freshwater for human use?

Back

Front

What is permafrost?

Back

Permafrost is a thick subsurface layer of soil that remains frozen throughout the year, often containing ground ice.

What is the significance of ground ice and permafrost?

Back

The percentage of ground ice and permafrost is greater than any other source of freshwater.

Front

What are the main sources of freshwater?

Back

The main sources of freshwater include glaciers, ice caps, groundwater, lakes, and rivers.

Front

Why is it difficult for humans to use water from glaciers?
