The physical breakdown of rock involves breaking rock down into smaller pieces through mechanical weathering processes. These processes include abrasion, frost wedging, pressure release (unloading), and organic activity.

is dissolved, worn away or broken down into smaller and smaller pieces. Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity. Mechanical weathering physically breaks up rock.

Weathering breaks down and loosens the surface minerals of rock so they can be transported away by agents of erosion such as water, wind and ice. There are two types of weathering: mechanical and chemical. Mechanical weathering is the disintegration of rock into smaller and smaller fragments.

Here are some words that are associated with small rock: stone, pebble, boulder, sedimentary, gravel, rock, soapstone, ashlar, stonemason, runestone, menhir, stonework, lodestone, stoneless, stoneware, sandstone, boulderstone, fieldstone, gritstone, tufa, logan, moonstone, krautrock, diorite, petrean, lithic, andesite.

A pebble is a clast of rock with a particle size of 4–64 mm (0.16–2.52 in) based on the Udden-Wentworth scale of sedimentology. Pebbles are generally considered larger than granules (2–4 mm (0.079–0.157 in) in diameter) and smaller than cobbles (64–256 mm (2.5–10.1 in) in diameter).

In other words, people can’t pull rocks out of the ground to take them away. The rocks that are taken away can also not be used commercially or sold, Lynch said. “But on the American River District, it’s not legal to even collect one rock,” Fischer said.

A shingle beach (also referred to as rocky beach or pebble beach) is a beach which is armoured with pebbles or small- to medium-sized cobbles (as opposed to fine sand).

The pebbles on Brighton beach are made from flint (a hard grey rock) deposited in the chalk cliffs adjacent to Brighton. Through natural erosion the flints are released from the cliffs and slowly make their way through natural process to Brighton where the groynes are in place to “capture” the pebbles.

Pieces of slate are generally found as very flat stones with rounded edges. White stones tend to stand out on a beach and they are stones which are rich in quartz. As quartz is one of the hardest minerals we have, it often remains when other softer rocks have eroded away.

Erosion is the wearing away of the land by forces such as water, wind, and ice. Erosion has helped to form many interesting features of the Earth’s surface including mountain peaks, valleys, and coastlines.

Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water. A similar process, weathering, breaks down or dissolves rock, but does not involve movement.

: the gradual destruction of something by natural forces (such as water, wind, or ice) : the process by which something is eroded or worn away.
