It is recommended that you put sand or pebbles at the bottom of a terrarium to allow drainage when watering plants.
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.

A sand layer in a terrarium helps to improve drainage and prevent the soil from becoming waterlogged. It also acts as a barrier between the soil and charcoal layer, which helps in keeping the terrarium ecosystem healthy by reducing the risk of mold and bacteria growth at the bottom.
Silt is the smallest particle size of boulders, pebbles, sand, and silt. It is finer than sand, pebbles, and boulders, which allows it to settle at the bottom first when suspended in water and has a low settling velocity.
Pebbles settled at the bottom of the glass container due to gravity. Gravity pulls the denser pebbles downwards, causing them to sink to the bottom while displacing water or lighter materials to rise above.
The Sand Pebbles was created in 1962.
One common technique used to separate pebbles and sand is sieving. By passing a mixture of pebbles and sand through a sieve with appropriate mesh size, the smaller particles such as sand will pass through while the larger pebbles will be retained on top of the sieve.

Sand and pebbles is a heterogeneous mixture. A solution is a homogeneous mixture.

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.
