At a brick factory along a river, stacks of identical bricks were left outside the building for shipment. A major flood destroyed the factory and washed away the bricks. Some bricks were carried several miles downstream; others were deposited close to the factory site. State two characteristics of the brick recovered far downstream that are likely to be different from the brick found near the factory site.
The rock fragments that are deposited downstream would appear smaller and rounder compared to the ones recovered near the factory site. Rocks become smaller and rounder due to the weathering and erosion that takes place when the water causes the rocks to rub against each other. As a result, the process of abrasion shapes the rocks and changes their appearance.
