Praxis 5511 Practice Test Practice Question
Scientists place a seismometer on the Moon. Which of the following are the scientists probably studying?
Correct Answer: A
Rationale: Scientists using a seismometer on the Moon are primarily studying ground movement, which involves detecting and analyzing seismic waves caused by moonquakes or impacts. This data helps understand the Moon's geological activity and structure.
Option B, magnetic fields, is not relevant as the Moon has a very weak magnetic field that wouldn't be measured by a seismometer. Option C, wind speed, is also incorrect since the Moon has no significant atmosphere to produce wind. Lastly, while studying gravitational changes (Option D) is important, it typically requires different instruments, such as gravimeters, rather than a seismometer focused on ground movement.
