Holes in pebbles can form through a process known as weathering. Over time, water, wind, or other environmental factors can erode and dissolve certain minerals within the pebble, resulting in the creation of holes or pits. Additionally, biological processes, such as the growth of organisms like algae or fungi, can contribute to the formation of holes in pebbles.

First, pebbles can be the result of larger rocks breaking up. Some of these large rocks were bedrock under a huge continent. A long time ago, the continents used to be one and then drifted apart to their current locations and are still drifting to this day. During this process, the "plates" under the ground move and collide with each other to from mountains, canyons, splitting of the earth, earthquakes, continent drift, and so on. During this, big rocks hit and little rocks. Second, once they are little rocks, they may go to the ocean and smoothed by water waves, they may fall down the mountain that is getting pushed up, or they may fall wherever they fall. Some of these pebbles are exposed to the weather. The changing temperatures causes the pebble to expand and shrink, causing cracks. Ice freezing in cracks splits the rocks up. Maybe the split-up wasn't perfectly even. Thus, there are some holes. Third, as time passes, debris and dirt may fall into the cracks allowing moisture and maybe plant growth. Plant roots can push and grow bigger to push the rock apart. Fourth, the little pebble of a result may bump into other rocks. This may cause the "holes" you are referring to. If the "holes" are air holes, then that can form when the rocks melt under the ground (lava) and gasses get trapped in the middle when the rock is liquid (like bubbles in your soda). When the lava cools and hardens, there may be a gas pocket inside. Maybe you can see this bubble inside if the rock happens to be small and clear enough.

Large holes cut in rocks at the base of sea cliff?

The form of beach stones is a result of weathering out of the rock from which the stone originated and abrasion by the sea. Sea abrasion will then to make the stone roundish and smooth, thus if there is a hole in it, it is either the result of the weathering process before the stone got to the sea or a shape inherent to the rock from the start. For instance in England, many beaches are made of flint pebbles where the flint comes form the eroded chalk cliffs. The flint in the chalk is irregular in shape and naturally has holes in it due to how it formed in the rock. Thus many pebbles will have depressions and holes in them when you find them on the beach. The other possible origin for holes in pebbles (made of limestone) is the action of certain marine worms which secret acid to bore holes in rocks so that they have a home to live in. This too could be a possible reason for beach stones with holes but only if the stones are made of limestone.


How can you separate sand and pebbles?

As long as the particles of sand and pebbles are of different size, you can separate them using a sieve (sifter). The smaller sand particles will pass through the sieve whereas the pebble molecules will not. This is the process that occurs in sifters sold as children's toys.

Can you separate sand salt pebbles and iron fillings?

Sure, that's easy. First, pull out the iron filings with a magnet. Separate the pebbles by pouring the mixture through a grate, with holes large enough to allow the sand and salt to fall through, but not large enough to allow the pebbles to fall through. Finally, to separate the sand and the salt, just add water. The salt will dissolve, the sand won't. If you want to recover the salt in solid form, you can then boil away the water in the salt solution, and get your salt back. Done.
