Some are, but some are larger. They come in different sizes.

Pebbles generally sink faster than sand due to their higher density and larger size. Sand particles are smaller and lighter, so they tend to float or settle more slowly in water compared to denser pebbles.
Meteors come in all sizes, from grains of sand to the size of a house; but I think it's safe to say thatmost meteors are smaller than artificial satellites.
Grains of sand will move faster compared to pebbles. Sand is lighter and will easily get carried by wind, unlike pebbles, which are heavier in comparison.
Yes, pebbles and sand are denser than water, so they will sink to the bottom. Over time, they can form a mixed layer as the smaller particles settle in between the larger pebbles.
Sand is more permeable than clay and pebbles because it has larger pore spaces between particles, allowing water to flow more easily through it. Clay has smaller pore spaces, making it less permeable. Pebbles have even larger spaces between them than sand, but water can still flow more easily through sand due to its finer texture.
Sand settles faster than pebbles and clay. Sand particles have smaller size and lower density, allowing them to quickly compact and settle in a sedimentation process. Pebbles are larger and denser, while clay particles are very fine and may take longer to settle due to their tendency to remain suspended in water.
Garden soil sand is more absorbent and retains the level of moisture for a longer period of time than pebbles. Pebbles or gravel should be put at the bottom of potted plants about 1/2 - 3 inches depending on the size of the pot for drainage.
Pebbles settle faster than sand grains due to their larger size and weight. The larger surface area of the pebbles and their higher density allow them to fall more quickly through the surrounding fluid. Sand grains are smaller and less dense, resulting in slower settling rates.

Yes, silt is smaller than sand.
Pebbles sink faster than sand grains due to their larger size, weight, and density. The larger surface area of pebbles compared to sand grains experiences less resistance as they sink through the water, allowing them to fall more quickly. Sand grains, being smaller and lighter, have a larger surface area that creates more friction with the water, slowing down their sinking rate.
