paper 1- glaciers

Question 1

what are glaciers

Answer 1

are made of snow that over hundreds of years, has been compressed into large, thickened ice masses and also contain rock and sediment

Question 2

stats about glaciers

Answer 2

glaciers cover 10% of the earths surface
85% glacial ice found in Antarctica
75% all earths freshwater frozen in glaciers

Question 3

what system is glaciers

Answer 3

open system- energy and matter can move in and out

Question 4

inputs of glaciers

Answer 4

snow, solar energy, hail avalanches, accumulation, rock debris from weathering/erosion

Question 5

outputs of glaciers

Answer 5

melting, ablation, previously eroded rock transported and deposited by the glacier, sublimation,calving

Question 6

zone of accumulation

Answer 6

area of g;acier where inputs bigger than outputs so mass gained

Question 7

zone of ablation

Answer 7

glacier where outputs bigger than inputs so mass lost

Question 8

equilibrium line

Answer 8

point which inputs and outputs balanced
