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.
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.
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.
boulders
The force of gravity typically settles second boulders or pebbles. When first larger boulders or rocks are placed, their weight and pressure help to stabilize and press down on the smaller boulders or pebbles, leading them to settle into place.
Silt and clay particles settle at greater fluid velocities than sand due to their smaller size and lower density. Sand particles require slower velocities to settle because they are larger and heavier.
The material left behind by a retreating glacier, including boulders, sand, clay, and silt, is known as moraine.
In this scenario, the gravel will settle out first, followed by the sand, and then the clay. Gravel has the largest grain size and weight, so it will settle out of the water column first. Sand will settle out next, followed by clay, which has the smallest grain size and weight.
They are both eroding rock particles.
ones harder then the other
Slump
Clay because it's lighter.
