Our Changing Earth: Earth is always on the move. Some forces are building up new landforms. Other forces are waring them down. Wind, water, and ice can break large landforms into small pieces. This process is called weathering. Some changes happen quickly. Other changes happen slowly. Weathering is a slow process.
Bit By Bit: Slow changes are hard to see. Mountains might take thousands of years to wear away. Only a few small rocks might break off each year. A river can change its course over time. This would be hard to notice, since it might only move 1 inch (2.5 cm) every few years. Water can freeze in the cracks of huge rocks. Over time, ice can break the rocks apart into small pieces.
