SLIP & SLIDEGLACIERS
Some glaciers move at a snail’s pace, while others advance more than a HUNDRED feet a day!
HOW DO GLACIERS MOVE?
A glacier is a large mass of ice that acts like a river, flowing downhill under the influence of gravity.
When the pressure builds up on the bottom layer, it melts and becomes soft & pliable, causing the glacier to slip downhill.

Place an ice cube on wax paper.
With one finger on top of the ice cube, push and slide at the same time.
Do it as long as you can.
What happened to your ice?
What part of the ice changed shape? (Your finger pressure and body heat caused the dip at the top)
What caused the melt?(pressure, friction and temperature of the room)
TRY THIS!
