Mostly just the weight of more snow and ice on top of it.

Why does the snow that forms a glacier change into ice?
simple . . it's because the glacier melted . . . The snow actually forms a glacier through a long process...a metamorphosis of sorts. Snow (which is an ice crystal) falls in an area that stays cold enough year round that snow doesn't totally melt in the summer. There has to be a large accumulation of snow and it must be in a place that isn't prone to avalanches or severe enough wind to blow the snow away. Or (as in the poles, the snow that falls stays because it stays cold enough that the snow doesn't melt all year.) Over a period of time, new layers of snow pile on top of previous snows, some parts melt so the layers pack more and more tightly. The transformation becomes known as firn. Eventually the firn transforms into a solid bluish mass filled with air bubbles. It can take a few decades or much longer.
What causes snow blindness?
the reflection of sunlight from ice or snow into the eyes.
What causes snow to sparkle in the sun?
Sometimes the snow can reflect light to your eyes that make you see the snow sparkle.
What is glaceir?
A huge mass of ice slowly flowing over a land mass, formed from compacted snow in an area where snow accumulation exceeds melting
What causes lightning in a snow storm?
The same thing that causes lightning in a rainstorm.
What is snow that survives one melting season?
Firn
What is snow that survives one melt season call?
Firn
Which air mass causes snow?
airness
What does a cubic yard of average moisture snow weigh?
The density of snow is variable. Wet snow or firn has a density which is almost 10 times that of freshly fallen flakes. Depending on its densit, a cubic yard of snow could weigh between 6700 poundals and 53800 poundals.

A large mass of snow and ice?
A large mass of snow and ice
What causes heavy snow?
Lot's of rain and cold weather causes heavy snow.
What causes rain sleet snow and hail?
Precipitation is what causes rain, sleet, snow, and hail.:)
What is the frozen ground that never thaws?
A frozen ground that never thaws is call firnward. Also, permafrost.
What causes water on the knee after snow skiing?
Snow residue.
What is the process of glacial ice formation?
1, Snowfall, 2, Settling of snow, loose granular consistency as the crystals begin to break up on collapse, and with the weight of overlying snow, plus partial melting. 3, Nivation, annual and diurnal temperature changes lead to thaw-freeze alternation and the conversion of snow into ice crystals. 4, Firn or Neve, increased pressure between individual grains causes pressure melting to eventually change the loose snow into a dull, white structureless mass. 5, Sintering, continued fusion and squeezing out of air as a result of compression by further accumulation. 6, Glacier ice, bluish in colour and containing little air, this may take 40-50 years, depending on the location.
