A rock with lots of tiny holes can float because these holes decrease its density, making it less heavy than the same amount of water it displaces. This reduced density allows the rock to overcome gravity and float on the surface of water.
The tiny holes in a rock are called vesicles. These are formed when gas bubbles that are trapped in molten lava solidify and become preserved in the rock as it cools.
Pumice has tiny air pockets to help it float in water.
true
the tiny little holes that appear on a leaf which is usually a fern or mosses are calles spores. spores are very tiny singe cells.
Tiny holes in the testa, called micropyles, act as passages for water to enter the seed for germination. They also allow for the exchange of gases during respiration in the seed.

pumice
Its porous, full of tiny holes and it floats.
It's just a disk-shaped object with LOTS of either tiny or big holes.
I'd say pumice is the closest to your description.
true
how the holes may get there is from the hot lava or magma and since it is very hot it may cause the holes i am not to sure though about my answer.When rocks are heated to melting point, bubbles of gas can get trapped in them. When the rock cools, the gas is left as a hole. Volcanic rock is chock full of holes.
Oil bearing rocks have millions of tiny holes where natural gas and oil are found.
a rock that is full of tiny, connected air spaces is PERMEABLE
A rock that can soak up water is called a porous rock. These rocks have tiny holes or spaces that allow water to be absorbed and held within them.
use lots of rock habitats and good luck ( plus patience)
