It is also made of rock, rather than fine-grained particles like sand. More importantly, the Moon doesn't have any weather, which means it doesn't have any wind. Since radio waves are vibrations I thought these vibrations could cause a small quake in the moon. Moonquakes originate in the Moon's core, which is more than a 1000 kilometers down. It is very unlikely that radio waves can penetrate to this level.
Scientists use radio waves to monitor weather, national defense and space exploration.
Waves are sent to the surface, bounce off and return to the probe. The surface of the object can be tested this way. The Apollo and Luna missions brought back 382 kg of rocks and soil back to Earth. These rocks, made of breccia, basalt and anorthosite, have told us a lot about the Moon. Even today, scientists are studying these rocks.
