Geography students investigated glacial retreat due to rising temperatures across four distinct mountain sectors in an alpine region.
Complete Table 1 by calculating the missing values for Beta and Delta.
Table 1: Glacial volume loss across four alpine sectors
| Sector | Original ice volume (km3km^3km3) | Volume lost to ablation (km3km^3km3) | Remaining ice volume (km3km^3km3) | % of ice volume lost |
|---|---|---|---|---|
| Alpha | 800 | 160 | 640 | 20 |
| Beta | 600 | 150 | 450 | (i) |
| Gamma | 1200 | 360 | 840 | 30 |
| Delta | 500 | 125 | (ii) | 25 |
