Erosion

Real World Example

Imagine trying to keep a sandcastle intact on a busy beach as waves continuously wash over it and other beachgoers walk by. Just as the relentless movement of water and footsteps gradually dismantles and disperses the sand, erosion involves the gradual wearing away and transportation of rock by natural forces like water, wind, or ice. In both scenarios, whether it's the sandcastle on the beach or the rock in nature, the constant action of external forces breaks down and carries away material bit by bit, altering the original structure over time.
