How does glacier ice form?
What will be an ideal response?
Glacier ice forms in two different ways:
One process is the metamorphism of snow into ice by recrystallization that changes the pointy snowflakes into a densely consolidated mass of intergrown ice crystals.
The other process is the summer melting of snow at the surface of the glacier with formation of ice as the meltwater infiltrates into the colder depths of the glacier.
