Making glacial connections

Transcription

1 Student task A 1.

Cut and arrange the cards below to make five sets of four connections: Five connections lateral U-shaped valley corrie truncated spur ground boulder clay flat floored freeze-thaw abrasion till arête outwash plain Lauterbrunnen terminal Matterhorn bulldozing plucking medial pyramidal peak drumlin 2. Explain each of the five connections fully Page 2 of 11

3 Student task C 1. Cut and arrange the cards below to make four sets of four connections and to leave four unconnected cards: Four connections plus Matterhorn solution drumlin flat floored Bangladesh pyramidal peak outwash plain hydrograph corrie till Mercalli U-shaped valley Lauterbrunnen freeze-thaw truncated spur abrasion plucking arête boulder clay bulldozing 2. Explain each of the four connections fully. 3. Define the terms on the four unconnected cards Page 3 of 11

4 Student task D 1. Cut and arrange the cards below to make five sets of four connections and to leave four unconnected cards: Five connections plus Matterhorn solution lateral flat floored medial pyramidal peak outwash plain hydrograph corrie till Mercalli U-shaped valley Lauterbrunnen freeze-thaw terminal abrasion plucking arête boulder clay ground Bangladesh drumlin truncated spur bulldozing 2. Explain each of the five connections fully. 3. Define the terms on the four unconnected cards Page 4 of 11

5 Student task E 1. Cut and arrange the cards below to make six sets of four connections: Six connections lateral U-shaped valley corrie truncated spur ground farming flat floored freeze-thaw arête till quarrying outwash plain Lauterbrunnen terminal Matterhorn bulldozing plucking medial drumlin forestry tourism boulder clay pyramidal peak abrasion 2. Explain each of the six connections fully Page 5 of 11

6 Student task F 1. Cut and arrange the cards below to make six sets of four connections and to leave eight unconnected cards: Six connections plus Matterhorn altitude corrie truncated spur ground farming flat floored freeze-thaw Spurn Head deciduous quarrying outwash plain Lauterbrunnen terminal meander soil plucking medial drumlin forestry tourism boulder clay pyramidal peak abrasion riprap, lateral managed retreat bulldozing U-shaped valley sheep arête till 2. Explain each connection fully Page 6 of 11

7 Suggested answers (student task A) Matterhorn pyramidal peak corrie arête Terminal Lateral Medial Ground Till Boulder clay Drumlin Outwash plain Lauterbrunnen U-shaped valley Truncated spur Flat floored The Matterhorn is a pyramidal peak in the Swiss Alps formed where corries in three adjacent valleys have eroded arêtes or knife edged ridges between them. Terminal, lateral, medial and ground are four types of moraine. Drumlins are made of till or boulder clay. Drumlins and outwash plains are depositional features of lowland glaciations. The Lauterbrunnen valley is a flat floored, U-shaped valley in Switzerland. The valley sides provide excellent examples of truncated spurs and alluvial fans. The image shows part of the 63 km long Baltoro glacier in the Karakorum mountain range of northern Pakistan. Links could be made to the pyramidal peaks of Concordia and Gasherbrum, corries, arêtes, glaciers, medial and lateral moraines etc. Anna, 2012, flic.kr/p/b7kpnr Page 7 of 11

8 Suggested answers (student task B) The connections grid on page two of the resource could be used either as an additional task after completion of the first connections grid or as a differentiated version. Matterhorn pyramidal peak corrie arête terminal lateral medial ground boulder clay till drumlin outwash plain Lauterbrunnen U-shaped valley truncated spur flat floored plucking abrasion freeze-thaw bulldozing The Matterhorn is a pyramidal peak in the Swiss Alps formed where corries in three adjacent valleys have eroded arêtes or knife edged ridges between them. Terminal, lateral, medial and ground are four types of moraine. Drumlins are made of till or boulder clay. Drumlins and outwash plains are depositional features of lowland glaciations. The Lauterbrunnen valley is a flat floored, U-shaped valley in Switzerland. The valley sides provide excellent examples of truncated spurs and alluvial fans. Plucking, abrasion, freeze-thaw and bulldozing are all processes of weathering or glacial erosion. Suggested answers (student task C) The answers are the same as for student task B, omitting the connection of the four types of moraine, but generate the four unconnected cards of Bangladesh, hydrograph, Mercalli and solution Page 8 of 11

9 Suggested answers (student task D) Connections grid D builds on the previous exercises. It introduces vocabulary that is more advanced. It could be used either as an additional task after completion of previous grid(s) or as a differentiated version, possibly for homework with the students being asked to provide illustrations/images of the terms together with a series of definitions. Matterhorn pyramidal peak arête corrie medial lateral terminal ground drumlin till boulder clay outwash plain plucking freeze-thaw bulldozing abrasion Lauterbrunnen U-shaped valley truncated spur flat floored Bangladesh Mercalli hydrograph solution The Matterhorn is a pyramidal peak in the Swiss Alps formed where corries in three adjacent valleys have eroded arêtes or knife edged ridges between them. Terminal, lateral, medial and ground are four types of moraine. Drumlins are made of till or boulder clay. Drumlins and outwash plains are depositional features of lowland glaciations. The Lauterbrunnen valley is a flat floored, U-shaped valley in Switzerland. The valley sides provide excellent examples of truncated spurs and alluvial fans. Plucking, abrasion, freeze-thaw and bulldozing are all processes of weathering or glacial erosion The four unconnected cards are: Bangladesh, hydrograph, Mercalli and solution Page 9 of 11

10 Suggested answers (student task E) Connections grid E is again a more advanced version of the previous five connections grids. It introduces four typical land uses in glaciated areas to provide six connections of four cards. No distractors are used. It could also be used either as an additional task after completion of previous grids or as a differentiated version, again possibly for homework with the students being asked to provide illustrations/images and definitions of the terms. The Matterhorn is a pyramidal peak in the Swiss Alps formed where corries in three adjacent valleys have eroded arêtes or knife edged ridges between them. Terminal, lateral, medial and ground are four types of moraine. Matterhorn pyramidal peak corrie arête terminal lateral medial ground drumlin till boulder clay outwash plain Lauterbrunnen flat floored U-shaped valley truncated spur plucking abrasion freeze-thaw bulldozing tourism farming forestry quarrying Drumlins are made of till or boulder clay. Drumlins and outwash plains are depositional features of lowland glaciations. The Lauterbrunnen valley is a flat floored, U-shaped valley in Switzerland. The valley sides provide excellent examples of truncated spurs and alluvial fans. Plucking, abrasion, freeze-thaw and bulldozing are all processes of weathering or glacial erosion Tourism, farming, forestry and quarrying are four typical land uses in glaciated areas Page 10 of 11

11 Suggested answers (student task F) Connections grid F again builds on the previous grids but uses six sets of connections and adds an additional layer of differentiation by using eight distractors. The connected answers are identical to those of student task E.

The eight unconnected cards are: altitude, Spurn Head, riprap, deciduous, soil, sheep, meander and managed retreat Page 11 of 11
