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.
true
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 little holes that appear on a leaf which is usually a fern or mosses are calles spores. spores are very tiny singe cells.
Yes, pumice is a volcanic rock that is characterized by its light, porous texture. It forms when lava cools rapidly and gases are trapped, creating numerous tiny holes or vesicles. These holes give pumice its buoyancy, allowing it to float on water. Its unique structure makes it useful in various applications, including abrasive materials and gardening.
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.

I'd say pumice is the closest to your description.

Craters
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.

tiny holes in the skin are called pores
