Document Summary
Lecture 4 - physical geography of arctic continued. Due to freezing and thawing, it contracts and then sinks into the ground. Vegetation around it is greener than the surrounding overall vegetation bc snowy owls perch on the rock and add nutrients to the vegetation with their pellet and feces. Soft liquid sediment pushed up to the surface (mud boiling). Soil with more moisture takes longer to lose heat and longer to freeze. When drier soil around it expands, squeezes wet soil and pushes it to surface. When things start to melt in june, water cycle starts to begin and rivers start to flow. This is the only time inuit people and communities have re-fresh of water. Cape bounty - snow melting off high points, channelizing and making up the east river into. Image: river water moves faster and river takes wet soil from the bank and picks up more material = thicker layer of sediment in river.
