glacial erosion activity

To integrate literacy skills into these lessons, try the following: Collab… With the weight of the ice over them, these rocks can scratch deeply into the underlying bedrock making long, parallel grooves in the bedrock, called glacial striations. Glacial erosion is the erosion form that results in the largest specific sediment loads (e.g. Kasei Valles has been imaged before by the HRSC during orbit 61 from an altitude of 272 kilometres. This is a laboratory experiment and lab writeup that is situated after lectures on glacier flow and erosion. We simultaneously quantified erosion rates and sliding velocity during a 5-month period, from November2013toApril2014,overtheentireFranz Josef Glacier, New Zealand. Students model rain erosion. Of these, glacial erosion is particularly difficult to constrain, despite its critical importance in the evolution of many mountain ranges. Discover a selection of new teaching materials and resources for educators, programs, and institutions found on SERC-hosted websites. Seasonal We had access to materials such as sand, foil, cooking oil (for a lubricated bed), U-shaped valleys (half-pipes), gravel, and water and tubing. The rate at which glaciers erode landscapes is an important but poorly constrained relationship. Data collection tools were simple, such as stop watches and rulers. 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. In this study, we present a new data set of 10 Be concentrations in fluvial sediments sampled The amount of sediment piling up at the edge of the glacier provided erosion rates, whereas remote sensing allowed for simultaneous tracking of glacial motion. Glacial meltwater seeps into cracks of the underlying rock, the water freezes and pushes pieces of rock outward. They record their observations and discuss the … Long-term erosion and crustal thinning in the Alaska Range is driven predominantly by cold-climate processes (i.e. Glacial erosion FREE (2) glacial, erosion, ice, land, plucking, abrasion, freeze thaw antony pearson Glaciation OCR GCSE 9-1A £ 2.00 (0) This covers glaciation for OCR. Unit Four: Background and Introduction, Winter, and adaptations to cold and snow. This is a bowl shaped steep walled depression carved out at the valley head. Processes of erosion and deposition in glacial environments result in a unique landscape. The small boulders that glaciers transport are fond deposited throughout the floor of the valley. Join today and your membership will help ensure that this site can continue to serve geoscience educators. We support geoscience education at every level. They are also economic, political, cultural and spiritual. 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. Glacial Erosion Erosion rate, E, increases with sliding velocity, U (E~10-4 U), and ice flux. This flux is, in long-term, dictated by snow input, hence erosion would tend to increase with amount of snow, S … Zapata Faroe Islands, source: Crary by Geology Activity B: Glacial Processes 4) Explain that is the difference between plucking and abrasion. Unit Two: Background and Introduction, From Work House, Native American Plant lore and use. Glacial erosion and relief production in the Eastern Sierra Nevada, California Simon H. Brocklehurst*, Kelin X. Whipple Department of Earth, Atmospheric and Planetary Sciences, Massachusetts Institute of Technology, Cambridge This lesson meets the following content standards of the National Science Education Standards: Earth and Space Science and Science in Personal and Social Perspectives. Synthesis of prior knowledge of glacier flow and erosion to make an experimental question.

Share your experiences and modifications,, All Sedimentary Geology related materials from across Teach the Earth, Schedule of Upcoming Workshops and Webinars, More Videos, Visit : Glacial Landforms and Glacier Erosion (Melting and Calving) is an animation video for Kids (Children). Using glacier goo along with a variety of other materials, design an experiment to study glacial erosion and how it ties to glacier motion and/or water content. With the pressure of more layers of snow, the firn will, over thousands of years, become glacier ice. Students should be qualitatively familiar with glacial flow, including sliding, deformation, cross-glacier flow, and changes with depth. 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. Herman et al. Cirques result from active plucking or quarrying at … The amount of halogens and boron found in the sediments accompanies a change in erosional activity. glacial erosion) (Fig. They should discuss or list how data should be collected and analyzed and potential problems with the experiment. Cirques, arêtes and horns: A cirque is one of the most impressive topographic feature associated with a valley glacier. 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. Call for a Robust Anti-racism Plan for the Geosciences. With more than 7,000 known glaciers, Pakistan has more glacial ice than any other country outside the polar regions. Content goals: Deeper understanding of glacier motion and glacier erosion through an experiment and experimental write-up. Students should have questions that the experiment seeks to answer; they should outline materials needed and steps needed for the experiment. The drumlins are tens of metres high, a few hundred metres across, and a few kilometres long. Show terms of use for text on this page », Show terms of use for media on this page », Rachel Headley, University of Wisconsin-Parkside. It’s been established that melting ice caps and volcanic activity are linked – but what we’ve found is that erosion also plays a key role in the cycle. Corries, cwms or cirques are the starting points for a glacier. Your membership is helping to ensure that this site can continue to serve geoscience educators. 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. A block of ice filled with sand and pebbles is used to demonstrate how glaciers sculpt and transform the land. The students discuss with the teacher how scientists determine glacial flow with real glaciers. Teach the Earth the portal for Earth Education, From NAGT's On the Cutting Edge Collection, This activity was selected for the On the Cutting Edge Reviewed Teaching Collection, This activity has received positive reviews in a peer review process involving five review categories. Some experiments will work much better than others. 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. 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. 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. Using a glacier proxy, students design an experiment to connect glacial erosion with glacial flow. 16.3 Glacial Erosion Glaciers are effective agents of erosion, especially in situations where the ice is not frozen to its base and can therefore slide over the bedrock or other sediment. 6a), while fluvial conditions prevail with glacial activity limited to the summit domains in the The five categories included in the process are. 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. For this reason, we have intentionally widened the scope of the units and activities to a trans- or cross-discipline approach, and an ecosystem perspective. This activity can be used in a mid- or upper-level glacial geology or geomorphology course in a geology or Earth science major. Writing a lab report and summary that someone else could follow to recreate their experiment. The rock is then plucked out and carried away by the flowing ice of the moving glacier (Figure below)., Alignment of Learning Goals, Activities, and Assessments, Robustness (usability and dependability of all components), Completeness of the ActivitySheet web page, Short URL: 5) Compare and contrast the two types of glacial drift Glacial erosion – a matching activity Can your students match the definition to the correct glacial key word or phrase? Activity 4: Track Traces – art project with animal tracks. Use of an analog model of a glacier. Unit Seven: Background and Introduction. how glacial erosion relates to ice-sliding velocity. Specific loads exceeding 1000 t … Erosion Researchers are studying modern reefs elevated by tectonic activity to simulate the erosion that took place during the glacial periods. Activity 3: Model Glaciers – forming mini … Effects of water on glacial flow and erosion could also be covered but this is not necessary. NAGT continues to support the crucial movement and petition for the Call for a Robust Anti-racism Plan for the Geosciences. Material on this page is offered under a tackle this issue by considering the Franz Josef alpine glacier in New Zealand. Unit One: Background and Introduction, From Work House, a Native American and geologic perspective on glaciers. They rotate through stations and model each type of erosion on rocks, soils and minerals. Tes Global Ltd is registered in … When a glacier cuts t… Students choose from a variety of materials, determined what question they want their experiment or experiments to answer, design the procedure, test the … Studies in old growth forest. The students use a glacier-modeling compound made from glue, water, and detergent (“flubber”) to predict and observe glacial flow. Glacial erosion transforms the narrow and V-shaped valleys created by streams into U-shaped valleys by widening the sides and deepening the bottoms of the valleys. The process is similar … Why are they important? Activity 1: Breaking it Down – the physics of glacial erosion. We’ve highlighted lessons on glacier formation and glacial movementin past issues. Activity 2: Carving Mountains – modeling glacial landforms. For more information about the peer review process itself, please see It uses the Lakes as an example. Being able to compare glacial erosion to fluvial erosion could also be helpful. The image above is Kasei Valles, one of the largest outflow channels on Mars, and contains a lot of evidence for glacial and fluvial activity over much of the planet's history. Glacial erosion includes the loosening of rock, sediment, or soil by glacial processes, and the entrainment and subsequent transportation of this … These hands-on activities simulate glacial flow. Using a glacier proxy, students design an experiment to connect glacial erosion with glacial flow. They make it rain on the landscape and observe the erosion that occurs. Students have already used some of the materials (including the glacier goo) for a lab on glacier flow. In this erosion instructional activity, students construct a landscape out of sand and dirt in a metal pan. Students should also be familiar with the processes of abrasion and plucking/quarrying with regard to glaciers. The On the Cutting Edge website and workshop program are supported by the National Association of Geoscience Teachers (NAGT). Creative Commons license unless otherwise noted below. Gurnell & Clark, 1987; Hallet et al., 1996). Working with others to test their experiment ideas. Unit Five: Background and Introduction. 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 Join us at, The On the Cutting Edge website and workshop program are supported by the National Association of Geoscience Teachers (NAGT). Mountain glaciers leave behind unique erosional features. Upcoming registration deadlines for the NAGT Webinar Series! These lessons focus primarily on glacial erosion. Because many experiments did not end up actually working, assessment was based more on the write ups of the experiment. The scouring action of the glaciers pulverizes minerals in the rock over which the glacier passes. The Himalaya and the Alps are full of such U-shaped valleys. Excellent as a plenary or revision exercise and the answers are provided together with an extension task. Erosion by wind, nivation, frost weathering, meltwater (e.g., Thorn, 2009) will modify much of the Critical Zone environment. Just as in the K-3 activities, the 4-6 activities focus on connections as illustrated in the journey of Pluie the wolf. The connections are not just biological. Join NAGT today. Through this hands-on activity, students explore five different forms of erosion: chemical, water, wind, glacier and temperature. Glaciers erode the underlying rock by abrasion and plucking. Unit Six: Background and Introduction, Student research and climate studies in the W-GIPP. Finally, they should also include a list or discussion of further variables to test. The rate of deposition reflects the amount of halogen and boron in the deposited sediments. Unit Three: Background and Introduction, From Work House, local people, animals and their environment. Many of the activities in this section are from Work House, the Glacier Science Education and American Indian Curriculum. Glacial erosion is the process in which a glacier moves across the earth and changes the landscape.
