#1 Which one of the following defnition is correct? 1. Block mountains: These are originated by tensile forces leading to the formation of rift valleys. They are also called as Horst Mountains. 2. Dome mountains: These are formed due to accumulation of volcanic materials. Different types of volcanic cones (e. g. cinder cones, composite cones, basic lava cones, etc.) come under this category 3. Mountains of Accumulations: These are originated by magmatic intrusions and upwarping of the crustal surface. Examples are: Normal domes, lava domes, batholithic domes, laccolithic domes, salt domes.. Select the correct answer using the codes given below
#2 Which one of the following is not the correct explanation for Plains?
#3 Consider the following statements regarding intrusive igneous rocks: 1. These are called Plutonic rocks. 2. Granite, diorite, gabbro are examples. 3. The intrusive rocks lying in a slanting direction as an off shoot are called dykes. Which of the above statements is/are correct?
#4 The process of converting unconsolidated sediments into sedimentary rocks requires which of the following?
#5 Which of the following are the reasons for the formation of metamorphic rocks? 1. High temperatures and pressures at depth cause changes in mineralogy, texture and composition. 2. Changes take place in solid state by crystallisation and chemical reactions. 3. Temperatures greater than 150°, less than 400°. Select the correct answer using the codes given below.
#6 Consider the following statements about Epeirogenic movement: 1. These are horizontal movements caused by tangential forces. 2. They cause large scale upliftment, subsidence of submergence and emergence of the land areas. 3. These movements are rather quick and widespread and fracturing and folding is produced in the rock. Which of the above statement(s) is/are correct?
#7 An earthquake is
#8 Which of the following are true with respect to sedimentary rocks? 1. the rocks are deposited in layers 2. at times the particles of rock are wholly organic in nature 3. the rocks are not crystalline 4. their structure is determined by great pressure or heat Choose the correct answer from the codes given below:
#9 Which of the following is/are matched not correctly?
#10 Which of the following are correct? 1. In the behaviour of earthquake waves, we study only three types of waves and they are ‘S’ – Surface waves, ‘L’ – Longitudinal waves and ‘P’ transverse. 2. The velocity of P – waves and S – waves increase with the depth throughout. 3. L – waves do not pass through the mantle because it is a liquid layer. 4. S – waves persists only to surface and do not penetrate deep into earth. Select the correct answer from the codes given below:
