Just a Minute. Achievement Objective: GM2-1: Create and use appropriate units and devices to measure length, area, volume and capacity, weight (mass), turn (angle), temperature, and time. In these five activities the students develop an understanding of the duration of minutes and seconds. We also practice reading time by counting the minutes after the hour.
Video: Glacial Erosion: Definition, Processes & Features. Glaciers are huge blocks of ice that move along the landscape, carving distinct features along the way. Learn about the glacial erosion processes, plucking and abrasion, and the features they create, including cirque, horns, arÃªte and roche moutonnee.
Ice sheets - large bodies of stagnant ice (except perhaps those at the poles. Glaciers - ice that is moving. So an ice sheet and an ice cap are more or less synonymous except for the location, and the key distinction to define a glacier is that it has to be moving. If a glacier were to stop moving (flowing) then it would be called an ice sheet or an ice field. Source(s):
