Question 1
If the glacial budget is balanced (accumulation equals wastage), then ________.
◦ the ice front will retreat
◦ the glacier will not flow downhill
◦ the terminus of the glacier is stationary
◦ the ice front will advance
Question 2
An ice skater's blade pushes down onto the ice very hard, creating water as a result of the pressure from the weight of the skater. How is her skate acting like a glacier?
◦ The weight of the ice in the top part of the glacier melts some of the ice at the bottom of the glacier, allowing for of plastic flow.
◦ Glaciers glide along the ground on only a small, thin blade of ice.
◦ When the skater produces water at the bottom of the skate, that water impedes her motion. In a similar way, the partially melted ice at the bottom of a glacier impedes its flow.
◦ Glaciers always move over smooth ground, and the skating rink is smooth.
