PDF version. The kinds of glaciers are continental glaciers, and valley glaciers. The grooves were most likely caused by Base your answers to questions 29 and 30 on the map below. In this lesson, students learn the effect that ice erosion has on the land through creating an interactive model. During that time the Northern and Eastern parts of the British Isles were covered in ice.
Ablation is the output of water from a glacier as the ice melts. The Great Lakes were carved out with the help of ice erosion. Glaciers can shape landscapes through erosion… A diagram showing erosional glacial features, as follows: 1 is a Pyramidal Peak; 2 is an Arête; 3 is a Corrie or Cirque; 4 is a Corrie Lochan or Tarn; 5 is an Alluvial Fan; 6 is a Ribbon Lake; 7 is a Truncated Spur; 8 is a Misfit Stream; 9 is a Hanging Valley; 10 is a 'U' Shaped Valley. Glacial-erosion cirque formation. A pyramidal peak is formed where three or more cirques and arêtes meet together. This rock sample was found in a gravel bank in central Vermont. The diagram below shows the formation of a corrie, cwm or cirque. Corries, also known as cwms or cirques, are often the starting point of a glacier. This can be near the North and South poles, and also on very high ground, such as large mountains. Pyramidal Peak. Glaciers erode the underlying rock by abrasion and plucking. Plucking is removal of entire chunks of rock. Glacial cirques are found amongst mountain ranges throughout the world; 'classic' cirques are typically about one kilometer long and one kilometer wide. The rock is then plucked out and carried away by the flowing ice of the moving glacier (Figure below). Glacial lakes are formed by ice erosion. View High-Resolution Image. In general terms, cold-based glacial erosion would be expected to move less rock per unit time than warm-based erosion because total ice movement is slower, and what movement does occur is preferentially remote from the ice-rock interface. Glacial erosion rate is usually modelled as a function of glacier sliding velocity, but the empirical basis for this relationship is weak. The glacier carves out a ditch in the Earth and the glacial water melts and is left behind. They are formed in areas where the general temperature is usually below freezing. Arrows on the map show the location The ice itself is not particularly effective at erosion because it is relatively soft (Mohs hardness 1.5 at 0°C); instead, it is the rock fragments embedded in the ice and pushed down onto the underlying surfaces that do most of the erosion. If three or more corries have formed on a mountain, erosion may lead to the formation of a single peak rather than a ridge. Yosemite Valley was carved out by large glaciers as the ice moved through the Sierra Nevada. They also deposit rocky material they have picked up, creating even more features. Geologists define a glacier as any large mass of ice that moves slowly over land. 3. Roches moutonnées range in size from several metres to several hundreds of metres across, and often occur in clusters 1 (see image below). Accumulation is the input of snow and ice into the glacier.
These geography worksheets look at the features and vocabulary used when studying glaciers and go on to label a diagram of a glacier. Glaciation; Glacial Erosion : Glaciation Glaciation is the study of ice and its impact on the environment.
Glacial Erosion. Continental glaciation tends to produce relatively flat bedrock surfaces, especially where the rock beneath is uniform in strength.
