Before you read, here are a few words you might want to know
• Glacier- a huge, moving, mass of ice, snow, rock, sediment, and water.
• Accumulation- the addition of snow and ice to a glacier • Ablation- the loss of snow and ice in a glacier • Firn- the middle stage in the changing of snow to glacier ice. • Advance- the addition of length to a glacier • Retreat- the loss of length to a glacier • Surge- a sudden short ‘surge’ of ice flow

How do glaciers form? How do glaciers form?
Glaciers are formed when snow and ice accumulates and is compressed into huge ice masses.

Not So Much Fun FactsNot So Much Fun Facts
• Glaciers, today cover 10% of all land area.
• But in the ice age they covered 32% of land and 30% of water area! That’s a lot!
• In the past 750,000 years there have been eight ice ages
• Right now we are not in and ice age but in an interglacial period.

Why do I care?Why do I care?
• Welllllllllllll… – The glaciers seem to be retreating a lot lately
and not so much moving forward. This may be do to the fact that we are in an interglacial period (not an ice age).
– This is called Climate Change! – This is not our fault, its just mother nature
(earth) warming up!

Types of these Glaciers! Types of these Glaciers!
The Valley Glacier (of doom!)They look like giant tongues when they spill
down into ‘valleys’ thus the name.
The Cirque Glacier (of happiness! )They are wide, not long, (I am being smarterer)
and found on the high mountain sides.
