Why do scientists belive that tectonic active is not accurring on the moon.

Scientists believe that tectonic activity is not occurring on the moon. This is because the moon lacks radioactive decay. The moon is not constantly supplied heat and energy from decaying unstable isotopes like Earth. Also, Earth is heated by the original heat during its formation. Since the moon was most likely broken off from earth, it lacks this central heat.@Kb0812    Hope this helps and if your feeling generous feel free to leave a rate, thanks and brainliest because it would really help me reach expert and I would appreciate it ;)
