1. Rewrite the correct statement : (1) The temperature range helps the wind in its work. Answer. Correct: The temperature range helps the wind in its work by causing mechanical weathering, which creates loose particles for wind to carry. (2) River’s work is more prominent than other agents of erosion in desert regions. Answer. Incorrect, rewrite: Wind’s work is more prominent than other agents of erosion in desert regions. (3) The work of groundwater is effective in the area with soft rocks. Answer. Correct: The work of groundwater is effective in areas with soft rocks because it can dissolve and erode them easily. (4) The work of wind is not limited like river, glacier or the sea waves and takes place everywhere. Answer. Correct: The work of wind is not limited like rivers, glaciers, or sea waves and takes place everywhere, especially in open areas. 2. Correct and rewrite the incorrect statements : (1) The ice on the lateral side of the glacier moves faster than the ice at the base. Answer. Incorrect, rewrite: The ice at the base of the glacier moves faster than the ice on the lateral side due to less friction. (2) The depositional work by rivers happens because of gentle slope, reduced speed and transported sediments. Answer. Correct: The depositional work by rivers happens because of gentle slope, reduced speed, and transported sediments. (3) A river flows at a faster speed than the glacier. Answer. Correct: A river flows at a faster speed than the glacier. (4) The speed of the glacier is more on both the banks than in the middle. Answer. Incorrect, rewrite: The speed of the glacier is more in the middle than on both the banks due to less friction. 3. Identify the wrong pair : (1) Deposition – V–shaped valley Answer. Wrong: V-shaped valleys are formed by erosion, not deposition. (2) Transport – Ripple Marks Answer. Correct: Ripple marks are linked to the transport and deposition of sand by wind or water. (3) Erosion – Mushroom Rocks Answer. Correct: Mushroom rocks are formed by the erosional work of wind. 4. Identify and name the landforms in the following diagrams : Answer. (i) V-shaped valley, (ii) Gorge (canyon), (iii) Delta. 5. Complete the following table by classifying the landforms according to their agents of erosion.(waterfall, delta, cirque, arête, barchans, moraine, pothole, mushroom rock, sinkholes, beach, pillars, lagoons) Answer. Rivers Wind Glacier Sea waves Ground Water Waterfall Barchans Cirque Beach Sinkholes Delta Mushroom rock Aretes Lagoons Pillars Pothole Moraine 6. Answer the following questions in brief. (1) List the landforms that are a result of the erosional work of the rivers. Answer. Gorges (canyons), V-shaped valleys and waterfalls are the result of the erosional work of the rivers. (i) ‘V’ Shaped Valley: (ii) Gorge: (iii) Waterfall: (2) Which agent is responsible for formation of stalactites and stalagmites and where are they formed? Answer. (3) List the landforms that are produced by the depositional work of the sea waves. Answer. Answer:The landforms like beaches, sand bar, lagoons are formed due to depositional work of the sea waves.(i) Beach: (ii) Lagoon: (iii) Sand bars: (4) Name the types of moraines. Answer. The glaciers carry sediments with them. These sediments are called moraines. Depending ond the location of the deposits, moraines can be divided into 4 types: ground moraines, lateral moraines, medial moraines and terminal moraines.
