| How
does the water get into glaciers and snowfields?
If there is leftover snow each year, snowfields will form and the snowfields
may turn into glaciers. How does a place wind up with leftover snow?—It
has to receive more snow than melts away every year!
How long does water
spend in glaciers and snowfields?
On average, a drop of water stays in snow for 150 days and a drop of water
stays in a glacier for 40 years.
How does water
get out of glaciers and snowfields?
The snow and ice melt, turning back into water, which flows away in streams
and rivers or soaks into the ground. Some of the frozen water turns into
water vapor gas and goes into the atmosphere in a process called sublimation.
