my son found a rock in the ocean and whenever he puts water on it the water dissappears. Its weird the way it happens, I wonder if it dries up or if its absorbed into the stone.

If you have a well, it gets water from an AQUIFER, a layer of water bearing rock. So I would recommend googling aquifer for precise information on the nature of water bearing rocks.
It could also be rewarding to turn this into a science project. I don't know that I would have been inquisitive enough to think of putting water on a rock, or observant enough to notice that the water disappeared, if it happened by accident.
I think that as children, we are force fed information that stifles our curiosity, for the sake of efficiency. This is an excellent opportunity to keep this natural curiosity alive in your son.
When I listened to Feynman's autobiography, he doesn't talk so much about his education. But he talks about investigating things that people accept at face value. He does talk about picking locks as an entertainment, so you may screen this book to see if it is suitable for your child.

Not an expert on geology or anything, but I'm guessing the rock is porous, has lots of little air holes/cavities and the water is absorbed as if the rock was a sponge. MOST rocks that you find in the soil have moisture content in them. I know that in order to work with some rock in the art of flint-knapping, spear head shaping, arrowhead shaping, the rock must first be heated, baked, etc in order to remove moisture.

Is anybody know here the water absorbent rocks for the purpose of house plantation.I mean I have not enough free time to daily watering my plants.

It is either sandstone or some sort of calcium bicarbonate....ie sea shell that has been worn down. The water is absorbed into the stone and then dries out later

Yes. Many "rocks" have that property. There was a NASA email I got a week or so ago about not only getting water, but oxygen from rocks on the moon. We are even getting oil from rocks in Canada. Lava rocks, for one, are very porous. So is limestone.
