#1 About 95 per cent of active volcanoes occur at the 1. plate subduction zones 2. transform faults 3. island arcs 4. mid-oceanic ridges Choose your answer from the following codes.
#2 Arrange the following rocks in a descending order in terms of silica content. 1. Andesite 2. Granite 3. Basalt 4. Rhyolite Choose the correct answer from the codes given below:
#3 Earthquakes are important in landform studies because they can trigger catastrophic events like 1. Landslides and mudﬂows 2. Glacier surges 3. Tsunamis causing damage and shoreline changes Select the correct answer from the codes given below.
#4 Consider the following statements: 1. The radial force lead to the epeirogenetic movements in earth plates. 2. Eurasian plate is made only of the continental crust. Which of the above statements is/are correct?
#5 The heat that caused melting in the Earth’s early history was supplied from which of the following events or causes? 1. Volcanic activity 2. Radioactivity 3. A large impact event 4. Solar heating Select the correct answer using the codes given below:
#6 Metamorphic rocks are changed rocks. Which of the following rock types could be the “parent” of a metamorphic rock? 1. Sedimentary 2. Igneous 3. Metamorphic
#7 The theory of plate tectonics was not initially widely accepted because:
#8 With reference to river as an agent of gradation, consider the following statements: 1. As a river overﬂows its banks during ﬂood, it drops much of its coarser-grained load immediately, forming landforms called natural levees. 2. Particles that roll and slide along the river bottom are called bed load. 3. At a bend in a river, deposition occurs on the outside of the bend and erosion occurs on the inside of the bend. Which of the statements given above is/are correct?
#9 With reference to the development of a River Valley consider the following statements and choose the correct one. 1. In the upper course of a river there is maximum gradient of slope. In this part the river has maximum erosive capacity. There is more down cutting than lateral cutting. 2. In the middle course the erosion and the deposition capacity of the river are almost equal. In this part the river ﬂows relatively with mild velocity. 3. In the lower course, the river runs at a slow speed or is slow paced. Its chief work is deposition. Select the correct answer using the codes given below:
#10 Features not associated with coastal deposition are: 1. Spits and Bars 2. Beaches 3. Marine Dunes 4. Goes and gloups
