glacial erosion activity

16.3 Glacial Erosion Figure 16.3.1 Drumlins — streamlined hills formed beneath a glacier, here made up of sediment — in the Amundsun Gulf region of Nunavut. Long-term erosion and crustal thinning in the Alaska Range is driven predominantly by cold-climate processes (i.e. Between latitudes 35°N and 35°S, glaciers occur only in the Himalayas, Andes, and a few high mountains in East Africa, Mexico, New Guinea and on Zard Kuh in Iran. The rate at which glaciers erode landscapes is an important but poorly constrained relationship. A block of ice filled with sand and pebbles is used to demonstrate how glaciers sculpt and transform the land. Students have already used some of the materials (including the glacier goo) for a lab on glacier flow. The connections are not just biological.

Through this hands-on activity, students explore five different forms of erosion: chemical, water, wind, glacier and temperature. We simultaneously quantified erosion rates and sliding velocity during a 5-month period, from November2013toApril2014,overtheentireFranz Josef Glacier, New Zealand. Unit Two: Background and Introduction, From Work House, Native American Plant lore and use. The students use a glacier-modeling compound made from glue, water, and detergent (“flubber”) to predict and observe glacial flow. http://creativecommons.org/licenses/by-nc-sa/3.0/, Alignment of Learning Goals, Activities, and Assessments, Robustness (usability and dependability of all components), Completeness of the ActivitySheet web page, Short URL: https://serc.carleton.edu/84754. Unit Four: Background and Introduction, Winter, and adaptations to cold and snow. Corries, cwms or cirques are the starting points for a glacier. The rock is then plucked out and carried away by the flowing ice of the moving glacier (Figure below). NAGT continues to support the crucial movement and petition for the Call for a Robust Anti-racism Plan for the Geosciences. Using a glacier proxy, students design an experiment to connect glacial erosion with glacial flow. The process is similar … Zapata Faroe Islands, source: Crary by Geology Activity B: Glacial Processes 4) Explain that is the difference between plucking and abrasion. The rate of deposition reflects the amount of halogen and boron in the deposited sediments. Activity 2: Carving Mountains – modeling glacial landforms. Along with the ecosystem focus, the 7 units of the 4-6 activities also include explanations and discussion of 5 of the other significant themes for why Glacier is protected as a national park- biodiversity, wilderness, Native American connections, International Peace Park designation, and geology. https://serc.carleton.edu/serc/about/whats_new.html. The total glacial erosion yield is determined to be proportional to the glacial coverage, sublinearly dependent on the precipitation rate, and linearly dependent on the glacial erosion constant that relates erosion with sliding The mission of The Geological Society of America is to advance geoscience research and discovery, service to society, stewardship of Earth, and the geosciences profession. Some experiments will work much better than others. Activity 3: Model Glaciers – forming mini … Glacial erosion is the erosion form that results in the largest specific sediment loads (e.g. Just as in the K-3 activities, the 4-6 activities focus on connections as illustrated in the journey of Pluie the wolf. There are not too many labs on glacier erosion: some involve putting ice cubes in a sandbox and seeing how material moves as they melt, which is fairly simple. 17.2 Glacial Erosion Glaciers are effective agents of erosion, especially in situations where the base of the glacier is not frozen to the underlying material and can therefore slide over the bedrock or other sediment. Researchers have found that glacial erosion and melting ice caps both played a key role in driving the observed global increase in volcanic activity at the end of the last ice age. This is a bowl shaped steep walled depression carved out at the valley head. Use of an analog model of a glacier. Call for a Robust Anti-racism Plan for the Geosciences. Because many experiments did not end up actually working, assessment was based more on the write ups of the experiment. Finally, they should also include a list or discussion of further variables to test. Processes of erosion and deposition in glacial environments result in a unique landscape. Students choose from a variety of materials, determined what question they want their experiment or experiments to answer, design the procedure, test the experiment, and write up a lab report on the experiment. Tes Global Ltd is registered in … Glaciers erode the underlying rock by abrasion and plucking. Glacial erosion is the process in which a glacier moves across the earth and changes the landscape. Effects of water on glacial flow and erosion could also be covered but this is not necessary.

Straight to the Pole (Grades K-2) A whole-class demonstration with a large “glacier” (made with a small trash can as a mold) and a sand table. Glacial meltwater seeps into cracks of the underlying rock, the water freezes and pushes pieces of rock outward. Why are they important? Excellent as a plenary or revision exercise and the answers are provided together with an extension task. These hands-on activities simulate glacial flow. 6a), while fluvial conditions prevail with glacial activity limited to the summit domains in the This flux is, in long-term, dictated by snow input, hence erosion would tend to increase with amount of snow, S … Erosion Researchers are studying modern reefs elevated by tectonic activity to simulate the erosion that took place during the glacial periods. This is a laboratory experiment and lab writeup that is situated after lectures on glacier flow and erosion. This activity can be used in a mid- or upper-level glacial geology or geomorphology course in a geology or Earth science major. It uses the Lakes as an example.
