Attrition: Rocks and stones that the river carries knock against each other, breaking into smaller, rounder, and smoother fragments. It's like a natural rock tumbler, where rough edges get smoothed over time. Solution (or Corrosion): This is a chemical process where certain rock types, like limestone or chalk, dissolve in the river's water ...

Abrasion vs Attrition. Abrasion refers to the mechanical scraping or grinding of rocks or sediments caused by the impact of other rocks, sediment, or abrasive particles such as sand. Attrition is the process of wearing down of rocks and sediments by collision and friction between particles, forming sedimentary rocks.

Erosional processes along coastlines include: (1) the direct effects of hydraulic action, wedging, and cavitation by waves; (2) abrasion (corrasion), using sand, gravel, and larger rock fragments as tools; (3) attrition of the rock particles themselves during this abrasive action; (4) salt weathering or fretting; (5) erosion by organisms (bioerosion); and (6) …

Formation of a sand dune. Windblown sand is deposited against an obstruction: Pebble or driftwood; As more sand particles are caught, the dunes grow in size, forming rows at right angles to the prevailing wind; Over time, the ridges of the dunes will be colonized and fixed by vegetation in a process called succession
