• Question 1 of 5 1. Question Consider the following statements: The northward movement of the Indian plate continues till date. A part of the Western peninsular region of India is submerged beneath the sea. The river valleys in the Peninsular region are deep with high gradients. How many of the above statements is/are correct? a) Only one b) Only two c) All three d) None Correct Solution: b) Statement 3 is incorrect. Over millions of years, the Indo-Australian plate broke into many parts and the Australian plate moved towards the south-eastern direction and the Indian plate to the north. This northward movement of the Indian plate is still continuing and it has significant consequences on the physical environment of the Indian subcontinent. The Peninsula has been standing like a rigid block with the exception of some of its western coast which is submerged beneath the sea and some other parts changed due to tectonic activity without affecting the original basement. As a part of the Indo-Australian Plate, it has been subjected to various vertical movements and block faulting. The rift valleys of the Narmada, the Tapi and the Mahanadi and the Satpura block mountains are some examples of it. The Peninsula mostly consists of relict and residual mountains like the Aravali hills, the Nallamala hills, the Javadi hills, the Veliconda hills, the Palkonda range and the Mahendragiri hills, etc. The river valleys here are shallow with low gradients Incorrect Solution: b) Statement 3 is incorrect.

• Question 2 of 5 2. Question Which of the following factors contribute to the evolution of landforms on earth? Movement of magma within the earth Growth and decay of vegetation Erosion and deposition Frost action How many of the above options is/are correct? a) Only one b) Only two c) Only three d) All four Correct Solution: d) Statement 1: It causes plate movements (tectonics), results in volcanic eruptions and is therefore a significant factor in the evolution of landforms on earth. Statement 2: If Vegetation cover is high, it protects the surface from rain splash as root mass is sufficient to stabilize the materials on the slope. Even surface runoff become less effective in carving out landforms in areas where there is dense vegetation, since there is little scope for soil erosion. Statement 3: Self-explanatory. For e.g. all the plains that you are the result of active erosion and deposition by water. Statement 4: When water freezes to ice, its volume increases. Under specific circumstances, this expansion is able to displace or fracture rocks where water exist in its pores. Repeated frost action thus weathers (breaks) the rocks. In some mountains, there are permanently frozen rivers of ice. They are called glaciers. Glaciers move at a very slow rate. When they do, they erode the soil beneath them. Also, formation of glaciers and their retreat affects the soil profile of the region and thus the landforms.

• Question 3 of 5 3. Question With reference to properties of lava, consider the following statements Basic lavas are the hottest lavas and are highly fluid When Basic lava flows from a volcano, it is very explosive Acid lavas are highly viscous and cause less explosive volcanoes Acid lava are also called as felsic lava Which of the above statements is/are correct? a) 1, 4 b) 2, 3 c) 1, 2, 4 d) 3, 4 Correct Solution: a) Highly fluid ones are less viscous, hence less explosive while the acidic ones are explosive due to high viscosity.

• Acid lava are also called as felsic lava
Which of the above statements is/are correct?
• c) 1, 2, 4
Solution: a)
Highly fluid ones are less viscous, hence less explosive while the acidic ones are explosive due to high viscosity.

• Question 4 of 5 4. Question Why the eastern and western boundaries of the Pacific Ocean experience frequent earthquakes? a) Due to the presence of deep ocean trenches along these margins. b) Due to presence of high mountain stretches along the continental belts c) Due to continuous wave and current action d) Due to these margins coinciding with the plate margins. Correct Solution: d) The region in question is the Ring of Fire. The Ring of Fire is a direct result of plate tectonics/ movement and collisions of lithospheric plates Since the margins coincide with the plate margins, the continous tectonic movements cause earthquakes. This region is also prone to high volcanism. Incorrect Solution: d) The region in question is the Ring of Fire. The Ring of Fire is a direct result of plate tectonics/ movement and collisions of lithospheric plates Since the margins coincide with the plate margins, the continous tectonic movements cause earthquakes.
