Question 1 of 20
Which specific soil condition is primarily required for liquefaction to take place during an earthquake?
Question 2 of 20
Earthquakes and volcanic eruptions are dynamic geological processes primarily classified as manifestations of:
Question 3 of 20
Which of the following are categorized strictly as secondary impacts of an earthquake?
Question 4 of 20
Why is the term 'Dormant' applied to volcanoes like Mt. Kilimanjaro?
Question 5 of 20
Which of the following is an extrusive geothermal feature characterized by the intermittent discharge of naturally heated groundwater and steam?
Question 6 of 20
Assertion (A): Decompression melting requires a massive localized spike in mantle temperature to initiate magma formation. Reason (R): Decreasing the overlying pressure on solid mantle rock significantly raises its melting point, preventing liquefaction.
Question 7 of 20
Assertion (A): The Modified Mercalli Scale provides subjective and variable values for a single earthquake. Reason (R): The Mercalli scale assesses the effects and structural damage caused by the earthquake, which naturally change based on the distance from the epicenter and local soil conditions.
Question 8 of 20
Match the depth or location given in List-I to its corresponding Seismic Feature in List-II: List-I 1. Approximately 2,900 km depth 2. Beyond 103° angular distance 3. Confined solely to surface rocks List-II A. The region of the massive S-wave Shadow Zone B. The medium of propagation for Love and Rayleigh Waves C. The Gutenberg Discontinuity separating Mantle and Core Choose the correct matching option:
Question 9 of 20
Assertion (A): P-waves can successfully traverse the Earth's liquid outer core. Reason (R): P-waves operate through compressional mechanics, and liquids possess the volume elasticity necessary to support this push-pull motion. Select the correct answer:
Question 10 of 20
What geomorphic phenomenon is commonly referred to as 'rock bursts'?
Question 11 of 20
Which prominent scientific theory explains the occurrence of earthquakes as the sudden release of accumulated stress when rocks snap back to a state of equilibrium?
Question 12 of 20
In the deep, open ocean, long before interacting with continental shelves, a tsunami wave typically traverses the water at kinetic speeds approaching:
Question 13 of 20
The mathematical formula to determine the velocity of a Primary wave (Vp) incorporates K (bulk modulus), μ (shear modulus), and ρ (density). Which of the following is the correct formula?
Question 14 of 20
The "Old Faithful" in Yellowstone National Park is a prominent example of which of the following natural phenomena?
Question 15 of 20
Which of the following describes a scenario where an earthquake alters river courses or creates depressions?
Question 16 of 20
What primary geological consequence arises when a divergent boundary undergoes 'Decompression Melting'?
Question 17 of 20
In structural geology, horizontal sheets of igneous rock that have intruded perfectly between the parallel layers of existing sedimentary strata are properly termed:
Question 18 of 20
Assertion (A): Deep-sea tectonic faulting strictly leads to highly destructive events with zero geomorphic benefits. Reason (R): Faulting can cause massive displacements of the crust, occasionally lifting the seafloor to create new islands or coastal plains.
Question 19 of 20
Consider the following statements regarding Mid-Ocean Ridge Volcanoes: 1. They occur primarily at convergent plate boundaries. 2. They are responsible for the formation of new oceanic crust. Which of the statements given above is/are correct?
