Show Hint
- P-4, Q-2, R-1, S-3
- P-4, Q-2, R-3, S-1
- P-3, Q-2, R-4, S-1
- P-2, Q-4, R-1, S-3
The Correct Option is A
Solution and Explanation
Step 1: Identifying the seismic discontinuities and their occurrences.
- The Conrad discontinuity is located between the lower and upper crust.
- The Mohorovičić (Moho) discontinuity is located between the crust and upper mantle.
- The Gutenberg discontinuity is located between the lower mantle and outer core.
- The Lehmann discontinuity is located between the inner and outer core.
Step 2: Analyzing the options.
(A) P-4, Q-2, R-1, S-3: Correct — This matches the seismic discontinuities with their corresponding locations in the Earth's interior.
(B) P-4, Q-2, R-3, S-1: Incorrect.
(C) P-3, Q-2, R-4, S-1: Incorrect.
(D) P-2, Q-4, R-1, S-3: Incorrect.
Step 3: Conclusion.
The correct answer is (A) P-4, Q-2, R-1, S-3, matching the seismic discontinuities with their corresponding positions in Earth's interior.

- The density contrast across which one of the following transitions in the Earth is maximum?
A magma having density of 2900 kg m\(^-3\) just reaches the surface through a two-layered crust as shown in the figure below. Assuming isostatic equilibrium, its depth of melting is .......... km. (Round off to one decimal place)
Refer to the schematic sketch given (not to scale). Assume average saturated density of oceanic crustal rocks = 3200 kg/m3, density of ocean water = 1000 kg/m3, and acceleration due to gravity = 10 m/s2. The overburden pressure at a point (P) located 2 km below seabed and 4 km below the ocean surface is ________ MPa. (Answer in integer.)
- Isostasy involves ................. continental mountain belts.
- A crustal rock is at a lithostatic pressure of 3 kbar and a temperature of 275°C. If the lithostatic pressure increases at a uniform rate of 0.3 kbar/km, and the surface temperature is 25°C, the geothermal gradient (in °C/km) is ....... (answer in one decimal place).
