- Q1What is glacial budget?Glacial budget is the balance between glacial's input and output.30s
- Q2What is accumulation?Accumulation is the input of snow and ice into the glacial system.30s
- Q3What is ablation?Ablation is the output of water from the glacial system.30s
- Q4More accumulation means?The glacier is advancing and has a positive regime.30s
- Q5More ablation means?The glacier is retreating and has a negative regime.30s
- Q6You get more accumulation in which part of the glacier?The upper part of the glacier know as (ZONE OF ACCUMULATION)30s
- Q7You get more ablation in which part of the glacier?The lower part of the glacier know as (ZONE OF ABLATION)30s
- Q8Why does a glacier advanceWhen accumulation is greater than ablation.30s
- Q9Why does a glacier retreatWhen ablation is greater that accumulation.30s
- Q10Describe the image...30s
- Q11In warmer times what happensMore ablation than accumulation therefore more meltwater is present leading to a negative regime.30s
- Q12In colder times what happensMore accumulation than ablation there for mote snow and ice is present leading to a positive regime.30s
- Q13How does snow turn into ice?4)Due to hight PMP ice melts but refreezes back into ice making the area more dense.30s
- Q14Warm base glacier.---Due to a lot of movement loots of erosion occurs.30s
- Q15Cold base glacier.---low erosion due to low movement.30s
