You are probably thinking of pumice, and igneous rock.
We call them clastic rock also referred to us the sedimentary rock.

Most Earth rock is igneous or metamorphic even though visible surface bedrock is mostly sedimentary. Of the total Earth rock volume, only a tiny fraction is sedimentary.
Yes, sand is basically tiny bits of rock that do not absorb much.
Granite is a type of rock or stone, and varies greatly in size, from as tiny as a pebble to as big as a mountain.

This type of rock is called pumice. Pumice is formed from volcanic eruptions, where the rapid cooling of lava traps gas bubbles inside the rock, creating its lightweight and porous structure.

It is because the rock is full of tiny air spaces that allow water to seep through it, so as the water seeps through the spaces it dissolves and removes material broken down by weathering. If you are doing this for a school science question, that's what textbooks are for. If not, then I can tell you are a person who enjoys to read and is a scientist.
