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.
Glaciers And Glaciation By definition a glacier is a mass of ice composed of compacted and recrystallized snow that flows under its own weight. This makes glaciers very effective agents of erosion, transportation and deposition of sediment. The two types of glaciers are Valley or Alpine glaciers Continental glaciers.
