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.
Simply stated, a glacier is a large, slow-moving mass of ice. While there are many types of glaciers, they can be divided into two categories: alpine and continental. Alpine glaciers are found in a mountainous region and flow down valleys.Continental glaciers are dome-shaped glaciers that flow away from a central region and are largely unaffected by the landâs topography. The Greenland and Antarctic ice sheets are examples of continental glaciers.Smaller masses of ice, called ice caps, are also considered continental glaciers. Alpine glaciers are further classified by their shape as well as the surface they flow onto.lpine glaciers flow down valleys, and continental glaciers flow outward in all directions from a central point. Glaciers move by two mechanisms: internal deformation and sliding. Internal deformation occurs when the enormous mass of a glacier causes it to spread out due to gravity.
