Since the weight of pumice is less it will float on water for some time and then..
Splash for little rock. SPLOOSH for big rock.
After you dropped a rock in a cup of water you noticed some displacement of the water on the counter.
Air, water, rock, space. Sound travels fastest through solids like rock, followed by liquids like water, then gases like air, and space is a vacuum where sound cannot travel at all.
No, rock is not a good conductor of sound. Sound travels better through materials that are less dense and more elastic, such as air or water. Rock is a dense and rigid material that restricts the transfer of sound waves.
The displacement and velocity of a rock that is dropped from rest after 4s, is 6 km/h. This can vary depending on the speed of the rock, and the surroundings.
Sound is a vibration of some physical material. There has to be a physical material for sound to travel through, from place to place. It doesn't have to be air. Water and rock work fine.

Yes, the potential for sound is made by the energy of the impact - (sound will occur in the hammer and in the rock), BUT the sound never leaves the hammer/rock as there is no air in space though which the sound waves can propagate.
It depends what the weight reading was originally measuring. If it was measuring the weight of the experimenter and the rock they were holding, and the water is not being held by them, then the weight will decrease by the weight of the rock. If it was measuring the weight of the water into which the rock it dropped, then it will increase by the weight of the rock. If it was measuring the weight of something totally unrelated to the experiment, then dropping the rock will have no measurable effect on the reading of the weight. Context needs to be given for the weight reading for a proper answer to be given.
A rock being stuck in it
Imagine a pool of water. If you dropped a rock in the water you would cause ripples that would travel out evenly in all directions. When one of those ripples hits a wall, you can see that the ripple bounces off the wall. Sound works the same way. Sound is basically just ripples in the air (vibrations). When a sound vibration hits a wall it bounces back much like the ripples in water.
The energy in the waves is transferred into other forms, such as heat through friction with the water and surrounding materials, as well as small vertical movements of the water particles. Eventually, the energy dissipates and is no longer noticeable as waves on the surface of the water.
Sit on a rock and ponder the meaning of life.
yeah, Frankie Jonas was in camp rock 2. he was the boy with the video camera which Kevin dropped in the water :)
The heat and pressure of the water can make cracks in the rock then break the rock.

Sound can travel through water, metal, rock and air, so the atmosphere isn't strictly needed for sound transmission.
