Glacier Dynamics Quiz

What is the key driver behind the mass balance of glaciers?

• Climate - precipitation

• Climate - temperature

• Climate - wind

• Geology - structure

What happens to glaciers when the temperature is above 0 degrees Celsius?

• Accumulation increases

• Melting and ablation occur

• Precipitation falls as snow

• Mass balance increases

Which factor provides inputs of snow, sleet, and rain to the glacial system?

• Climate - wind

• Geology - lithology

• Climate - precipitation

• Geology - structure

What happens to precipitation below 0 degrees Celsius?

• Falls as rain

• Melts

• Falls as snow

• Increases outputs

What is the effect of high wind speeds on glaciers?

• Increases mass balance

• Forms rime ice on the surface

• Decreases erosion

• Provides snow

What is the characteristic of rocks with primary permeability?

• Easily eroded

• No air spaces

• Harder to weather

• No chemical composition

What is the role of climate - wind in the glacial system?

• Provides snow and rain

• Inputs fine-grained sediment and rime ice

• Increases mass balance

• Influences the shape of landforms

What is the effect of high latitude areas on glaciers?

• They have warm, wet climates with high seasonal variation.

• They maintain a positive budget and grow over time into large ice sheets.

• They cause glaciers to melt rapidly.

• They have no effect on glaciers.

What happens to the snow line on mountain tops as you move closer to the equator?

• It decreases in height.

• It increases in height.

• It remains the same.

• It disappears completely.

Which of the following refers to the direction a slope is facing?

• Latitude

• Relief

• Aspect

• Sediment inputs
