Question

1. two students designed the experiment shown below to study stream erosion. a steady stream of water flows from a faucet into a tray holding sand and gravel. the water forms a channel by eroding some of the sand and gravel. how can the students increase the amount of sand and gravel being eroded? by adding coarse gravel to the tray by increasing the water temperature by increasing the tilt of the tray by reducing the amount of flowing water 13. the process that breaks rocks apart without changing their chemical composition. chemical weathering deposition erasion physical weathering

Explanation:

For the first question, increasing the tilt of the tray increases the speed and force of the water flow, leading to more erosion. Adding coarse gravel makes erosion harder, water - temperature has little impact on this type of erosion, and reducing water amount decreases erosion. For the second question, physical weathering breaks rocks apart without changing their chemical composition. Chemical weathering changes the chemical makeup, deposition is the laying down of sediment, and erosion is the movement of sediment.

Answer:

1. By increasing the tilt of the tray
2. Physical Weathering
