Sedimentary. It makes sense. Sediment floats to the bottom of a lake or ocean and the pressure of the water compresses the material into rocks over time, sometimes trapping fossils. This happens over many years. These rocks are the types that have stripes on them.
One effective way to separate grit from small pebbles is to use a sieve or a screen with appropriately sized holes. Pour the mixture onto the sieve or screen and shake it gently so that the small pebbles remain on top while the finer grit falls through. Alternatively, you can also use water to separate them by pouring the mixture into water and allowing the grit to sink to the bottom while the pebbles float.
Pebbles can have holes due to erosion, often from being tumbled in rivers or waves which causes wear and tear on the stone, creating small crevices or holes. Additionally, some pebbles may have formed with holes naturally as a result of the rock's formation process and mineral composition.
No, pebbles are not necessarily igneous rocks by default. Pebbles can be formed from a variety of rock types, including igneous, sedimentary, and metamorphic rocks, depending on the geological processes that created them.
clay and silt
Sand-sized particles, like sand grains and small pebbles, are usually moved by saltation. These particles are lifted and carried by the wind in short, intermittent jumps before falling back to the ground.

The small pebbles are more likely to fall through the gaps between bigger pebbles than the other way around.

Small particles of sand, silt, and clay
Yes, wind erosion can pick up small particles (such as sand) and leave behind heavier particles (such as rocks or pebbles) in a process known as deflation. This selective removal of finer particles can lead to the formation of features like sand dunes.
Pebbles? I think you could call them pebbles.
In its simplest form, erosion. More specifically, the pebbles can undergo saltation or particle transport (bottom hopping) when there is little silt in the water.

Wind can skip and bounce small particles like dust and sand for short distances. Larger particles such as pebbles or rocks are less likely to be lifted and moved by the wind in this manner.
