2 Section A : Data-Response Questions Answer, both Questions 1 and 2 in the Answer Booklet. 1. Resource 1 shows 2 different features, 1A and 1B, which have been affected by weathering processes. Resource 2 shows Peltier’s model on weathering on a global scale. Resource 3 shows Strakhov’s model on basal surface of weathering on a global scale. (a) Identify and explain the weathering process which could have contributed to the feature shown in Resource 1A. [3] (b) Explain the weathering process/es which may have contributed to the weathering of the feature shown in Resource 1B. [6] (c) Explain the role-played by geology in affecting the features shown in Resources 1A and 1B. [5] (d) With the use of a diagram, account for a weathering process which functions at the region highlighted in green ( ), in Resource 2 . [5] (e) With reference to Resource 2, explain the role played by climate on the type and rates of weathering processes in the humid and arid regions. [6] (f) Suggest reasons for the depth of weathering between regions Y and Z, shown in Resource 3. [5]

3 2. Resource 4 shows the climate graph of Ho Chi Minh, Vietnam. Resource 5 shows a table with the data of 2 rivers, A and B. Resource 6 shows a part of the Saigon river (middle course), Ho Chi Minh, Vietnam. (a) Cite data from Resource 4 to describe the climate characteristics of Ho Chi Minh, Vietnam. [5] (b) With reference to Resource 5, explain which river, A or B, is more efficient. [6] (c) With reference to Resource 6, describe the dominant fluvial processes in the Saigon River. For evidence of the fluvial processes, annotate on Resource 6. Detach Resource 6 on Page 6 and Submit Resource 6 with your Answer Booklet. [5] (d) Explain why the finer sediment load such as clay (smaller than 0.002mm in diametre) requires similar velocity to be transported/entrained as coarser sediment such as gravel (4 mm to 64mm in diameter)? [3] (e) Explain why the mean velocity
