They performed geological and chemical analysis of the samples.

Moon rocks were collected from the moon by Apollo astronauts.
The astronauts collected moon rocks and moon dust.
They found craters and dust.
Not sure Apollo II did, I think it was later flights, but yes they brought rocks back. Even to day some have never been analyzed.
Apollo 11 astronauts collected moon rocks and a cloth was put to collect moon dust that stuck to it.
Yes, the Apollo 11 astronauts collected 50 basalt and breccia rocks from the lunar surface. Later missions collected more, as the first mission was short in comparison.
The astronauts walked on the moon, collected rocks, took photographs, left equipment on the moon, a flag, they got a phone call from Richard Nixon, left gold medals in honor of the 5 astronauts who died.
All of the missions that actually landed brought back moon rocks . These were the missions of Apollo 11, 12, 14, 15, 16, and 17. The Apollo 17 mission was of particular importance geologically, because one of the astronauts, Harrison Schmidt, was a geologist.
The shaking or vibration in the underground rocks of the moon is called a moonquake. Moonquakes were first discovered by the Apollo astronauts and are known to last for as long as an hour.
Because there is no known life on the moon. The rocks brought back by the Apollo astronauts showed no evidence of life in the past either.
