Document Summary
A kame is an irregularly shaped hill composed of sand, gravel, and till. It happens during summer months when melt water flow through crevasses of the glacier on land surface. An esker is when ice melts, long twisting steep sided stratified ridges of sediments are formed. Crevasses fill are the spaces and cracks in the glacier and may be filled with melt water and other sediments. Glacier delta is when deposited materials causes the glacier to divide into several channels which is triangular in shape. This occurs when melt water and glacier materials flow into the bay. Is broken piece of ice that drifts from the current and melt or reduce overtime. Abrasion is the process in which the ice uses the sediments it carries to scrape pieces of stones from the bedrock to make it smoother. Fiords is a glacial valley that extends from mountainous area.
