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.

Yes, water remains water even after dropping Alka Seltzer in it. The Alka Seltzer will dissolve in water, releasing bubbles of carbon dioxide gas, but the composition of the water itself does not change.
The water flows over a water fall
Sedimentary rock is formed by suspended solids dropping to the bottom and building layers that will compress down under the weight of water and go hard after the water source has disappeared, and the moisture has evaporated out of the silt left behind.
yes it is a physical change !
Dropping a pencil in the water will produce ripples.
No. That is you dropping a pound or two of water weight and then gaining back that and more due to the drop in your metabolism from not eating for two days.
Dropping water tables can lead to land subsidence, where the ground sinks due to the decreased water support. This can damage infrastructure and reduce water availability for communities, ecosystems, and agriculture. It can also increase the concentration of pollutants in the remaining water, impacting water quality.
Glaciers and ice caps are melting and adding water. The oceans are also warming, and warm water expands, taking up more space than cooler water. So the sea levels are not only not dropping, they are rising.
Dropping a stone into water will produce circular waves that spread outwards from the point of impact. These waves are called ripples and are a type of surface wave.
After the dropping have dffused into the water in the water in the drum dilute the concentrate and water your plants.
