Esker formation in subglacial fractures. Eskers form when meltwater flows through fractures between ice masses When the water slows, it deposits sediment in long, sinuous patterns Eskers are confined within glacial margins then spread beyond terminal moraines
Eskers are sinuous ridges formed when meltwater flows through fractures between ice masses. As water slows, it deposits sediment in long, snake-like patterns. These features form confined within glacial margins then spread beyond terminal moraines during ice sheet collapse and breakup. 🏔️💧 21:30-24:30
Key Facts
- Eskers form when meltwater flows through fractures between ice masses
- When the water slows, it deposits sediment in long, sinuous patterns
- Eskers are confined within glacial margins then spread beyond terminal moraines
- Eskers form during the collapse and breakup of ice sheets
- The formation involves both large-scale fracturing and melting of ice masses
