When pieces of chalk are shaken in a jar with pebbles, they will break down into smaller pieces due to the abrasive action of the pebbles rubbing against them. This process is known as abrasion and will result in the chalk becoming smoother and rounder over time.

Weathering breaks down rocks into smaller pieces, erosion transports these pieces downhill, and deposition deposits these pieces in lower-lying areas. In hill country, this can result in the gradual reshaping of the landscape, leading to the formation of valleys, slopes, and terraces over time.
