They are both eroding rock particles.
boulders
Boulders settle first, followed by pebbles, then sand. This is because boulders are the heaviest and tend to settle fastest, while sand is the lightest and takes longer to settle.
boulders
Has loose soil, boulders, sand, and gravel as its parent materials. Also is very common in New England.
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.
The material left behind by a retreating glacier, including boulders, sand, clay, and silt, is known as moraine.
Sand would settle first, as it has the smallest particle size and can easily compact together. Boulders, being the largest, would settle last due to their size and weight. Pebbles would settle between sand and boulders in terms of settling time.

The boulders, sand, clay, and silt that are deposited by a glacier as it slows down and melts are called glacial till. This material is unsorted and varies in size, ranging from large boulders to fine silt. Glacial till is often found as moraines, which are accumulations of debris along the edges or at the terminus of a glacier.
