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?
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.
