Hey future geographers! Ready to chill with glaciers? Let's slide into the world of glacial deposition, where glaciers don't just melt away; they leave a footprint (well, more like boulders, rocks, and pebbles) behind! 🎿

laciers can be messy creatures, leaving behind all kinds of different rocks and particles.

• Lodgement Till: When a glacier's actively moving, it drops material. Imagine tripping while running with a bag of mixed candy; that's lodgement till!
• Ablation Till: This is what's left behind when a glacier is stagnant or retreating. Imagine the candy bag bursting as you stop and rest.
• Characteristics:
  • Poor Sorting: Like a messy candy mix of boulders, pebbles, and clay!
  • Poor Stratification: No organized layers here, just chaos.
  • Rock Variety: From different sources, like getting candy from different stores.
  • Striated/Subangular Particles: Some rocks show lines or rough edges.
  • Orientation: Like arrows, these point in the direction of glacier flow.
  • Compaction: Things get squished together.

These are rocks carried and dropped by glaciers. Think of them as a glacier's rock garden.

• Terminal Moraine: This crescent-shaped mound is the farthest the glacier went. Example: Cape Cod in Massachusetts, USA.
• Lateral Moraine: A ridge running along the edge of a glacier. It's like a rocky side road! Example: Gorner Glacier in Switzerland.
• Medial Moraine: When two glaciers meet and their lateral moraines combine. Like a rocky high-five! Example: Also Gorner Glacier.
