Q. With reference to marsquake, consider the following statements::
1.These are caused by shifts in Martian tectonic plates.
2.InSight Mars lander has detected the largest quake ever observed on Mars.
Which of the statements given above is/are correct?

[A] 1 only

[B] .2 only

[C] .Both 1 and 2

[D] Neither 1 nor 2

Answer: B
Notes:

Statement 1 is incorrect: On Earth, quakes are caused by shifts in tectonic plates.

However, Mars does not have tectonic plates and its crust is a giant plate. Therefore, NASA notes, ‘marsquakes’ are caused due to stresses that cause rock fractures or faults in their crust.

Statement 2 is correct: InSight Mars lander has detected the largest quake ever observed on another planet including Mars.
