11. Which of the following statement is correct about the Lehmann Discontinuity?
[A] The boundary between the upper crust and the lower crust
[B] The boundary between inner core and outer core
[C] The boundary between outer core and the mantle
[D] The boundary between the crust and the mantle
Show Answer
Correct Answer: B [The boundary between inner core and outer core]
Notes:
The boundary between the inner core and the outer core is called as the Lehmann Discontinuity. It is also called as the Lehmann-Bullen discontinuity.
12. Which metamorphism happens without any appreciable chemical change?
[A] Dynamic Metamorphism
[B] Thermal Metamorphism
[C] Contact Metamorphism
[D] Regional Metamorphism
Show Answer
Correct Answer: A [Dynamic Metamorphism]
Notes:
In Dynamic Metamorphism mechanical forces are dominant and it therefore does not lead to any considerable chemical change.
13. What are deep focus earthquakes also known as?
[A] Crustal earthquakes
[B] Intraplate earthquakes
[C] Both 1 & 2
[D] Neither 1 & 2
Show Answer
Correct Answer: B [Intraplate earthquakes]
Notes:
Deep focus earthquakes are earthquakes deeper than 70 km. They occur in pattern of Benioff zones. They are triggered by collision between two plates hence called as Intraplate earthquakes.
14. Which among the following is not a characteristic of Primary waves?
[A] They are similar to sound waves
[B] They are transverse waves
[C] They travel through all mediums
[D] They are first to reach the surface
Show Answer
Correct Answer: B [They are transverse waves]
Notes:
Primary waves ( P – Waves) are the first to reach the surface.
They are similar to sound waves and hence they are longitudinal waves – in which particle movement is in the same direction of wave propagation.
Secondary waves are transverse waves.
15. Which among the following is a biological environment based on a limestone plain with thin or no soil called?
[A] Alvars
[B] Lavakas
[C] Lahars
[D] Hoodoo
Show Answer
Correct Answer: A [Alvars]

16. What is the landform that descends towards a valley floor or coastline from a higher elevation ending in an inverted-V face?
[A] Truncated Spur
[B] Tor
[C] Barkhans
[D] Hogback
Show Answer
Correct Answer: A [Truncated Spur]
Notes:
Truncated spurs are erosional landforms. It is a ridge which descends towards a valley floor from a higher elevation ending in an inverted-V face.
17. What is a series of regular sinuous curves, bends, loops, turns, or windings in the channel of a river, stream, or other watercourse called?
[A] Lahars
[B] Floodplain
[C] Ox bow lake
[D] Meander
Show Answer
Correct Answer: D [Meander]
Notes:
Meander is a sinuous turn, loop or curve in the river channel. The degree of the meandering of the channel of the river or stream is measured by sinuosity
18. Which of the following nation shares the border with Albania to house, both the nations highest peak, Mount Korab?
[A] Greece
[B] Montenegro
[C] North Macedonia
[D] Kosovo
Show Answer
Correct Answer: C [North Macedonia]

[A] Monadrocks
[B] Inselbergs
[C] Tors
[D] Nunataks
Show Answer
Correct Answer: D [Nunataks]
Notes:

20. Which among the following statements is not correct about Mid Oceanic ridge?
[A] They are underwater mountain system formed by plate tectonics
[B] They are formed at convergent plate boundaries
[C] They are the longest mountain ranges of the world.
[D] They are formed due to the process of sea floor spreading
Show Answer
Correct Answer: B [They are formed at convergent plate boundaries]
Notes:
The underwater mountain system formed by plate tectonic spreading is called the Mid oceanic ridge. They are formed by plate tectonics due to the process of sea floor spreading. They are formed at divergent plate boundaries. They are the longest mountain ranges of the world.
