- Glacial movement & temperature
- Pressure melting point (PMP)
- The temperature at which ice is on the verge of melting
- A small increase n pressure can cause melting
- PMP is normally 0°C at the surface of a glacier
- Warm & cold ice
- Warm ice has a temperature of around 0°C (PMP) throughout its depth
- Temperatures in cold ice and permanently below 0°C (PMP) & so there is virtually no melting
- Glaciers with mainly warm ice are called temperate
- Glaciers with cold ice are called polar
- Because meltwater helps glaciers to move, movements much faster in temperate glaciers then polar
